     The undersigned acknowledges receipt of the Prospectus dated [   ], 1999
(the "Prospectus") of Federal-Mogul Corporation (the "Company"), and this Letter
of Transmittal (the "Letter of Transmittal"), which together describe the
Company's offer (the "Exchange Offer") to exchange $1,000 in principal amount of
its new 7 3/8% Notes due 2006 (the "New 7 3/8% Notes") for each $1,000 in
principal amount of outstanding 7 3/8% Notes due 2006 (the "Old 7% Notes") and
$1,000 in principal amount of new 7 1/2% Notes due 2009 (the "New 7 1/2% Notes"
and together with the New 7 3/8% Notes, the "New Notes") for each $1,000 in
principal amount of outstanding 7 1/2% Notes due 2009 (the "Old 7 1/2% Notes"
and together with the Old 7 3/8% Notes, the "Old Notes"). The terms of the New
Notes are identical in all material respects (including principal amount,
interest rate and maturity) to the terms of the Old Notes for which they may be
exchanged pursuant to the Exchange Offer, except that the New Notes are freely
transferable by holders thereof (except as provided herein or in the Prospectus)
and are not subject to any covenant regarding registration under the Securities
Act of 1933, as amended (the "Securities Act").

    The undersigned has checked the appropriate boxes below and signed this
Letter of Transmittal to indicate the action the undersigned desires to take
with respect to the Exchange Offer.

     If the undersigned is not a broker-dealer, the undersigned represents that
it is not engaged in, and does not intend to engage in, a distribution of New
Notes. If the undersigned is a broker-dealer that will receive New Notes for its
own account in exchange for Old Notes that were acquired as result of market-
making activities or other trading activities, it acknowledges that it will
deliver a prospectus in connection with any resale of such New Notes; however,
by so acknowledging and by delivering a prospectus, the undersigned will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act. A broker-dealer may not participate in the Exchange Offer with respect to
Old Notes acquired other than as a result of market-making activities or other
trading activities. Any holder who is an "affiliate" of the Company or who has
an arrangement or understanding with respect to the distribution of the New
Notes to be acquired pursuant to the Exchange Offer, or any broker-dealer who
purchased Old Notes from the Company to resell pursuant to Rule 144A under the
Securities Act or any other available exemption under the Securities Act must
comply with the registration and prospectus delivery requirements under the
Securities Act.

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the above-described principal amount
of the Old Notes indicated above. Subject to, and effective upon, the acceptance
for exchange of the Old Notes tendered herewith, the undersigned hereby
exchanges, assigns and transfers to, or upon the order of, the Company all
right, title and interest in and to such Old Notes. The undersigned hereby
irrevocably constitutes and appoints the Exchange Agent the true and lawful
agent and attorney-in-fact of the undersigned (with full knowledge that said
Exchange Agent acts as the agent of the Company, in connection with the Exchange
Offer) to cause the Old Notes to be assigned, transferred and exchanged. The
undersigned represents and warrants that it has full power and authority to
tender, exchange, assign and transfer the Old Notes and to acquire New Notes
issuable upon the exchange of such tendered Old Notes, and that, when the same
are accepted for exchange, the Company will acquire good and unencumbered title
to the tendered Old Notes, free and clear of all liens, restrictions, charges
and encumbrances and not subject to any adverse claim. The undersigned also
warrants that it will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or the Company to be necessary or
desirable to complete the exchange, assignment and transfer of tendered Old
Notes or transfer ownership of such Old Notes on the account books maintained by
the book-entry transfer facility. The undersigned further agrees that acceptance
of any and all validly tendered Old Notes by the Company and the issuance of New
Notes in exchange therefor shall constitute performance in full by the Company
of its obligations under the Registration Rights Agreement (as defined in the
Prospectus) and that the Company shall have no further obligations or
liabilities thereunder except as expressly provided for in said agreement.

     The Exchange Offer is subject to certain conditions as set forth in the
Prospectus under the caption "The Exchange Offer; Registration Rights--Certain
Conditions to the Exchange Offer." The undersigned recognizes that as a result
of these conditions (which may be waived, in whole or in part, by the Company),
as more particularly set forth in the Prospectus, the Company may not be
required to exchange any of the Old Notes tendered hereby and, in such event,
the Old Notes not exchanged will be returned to the undersigned at the address
shown above. In addition, the Company may amend the Exchange Offer at any time
prior to the Expiration Date if any of the conditions set forth under "Exchange
Offer; Registration Rights--Certain Conditions to the Exchange Offer" occur.

     By tendering, each holder of Old Notes represents that the New Notes
acquired in the exchange will be obtained in the ordinary course of such
holder's business, that such holder has no arrangement with any person to
participate in the distribution of such New Notes, that such holder is not an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act and that such holder is not engaged in, and does not intend to engage in, a
distribution of the New Notes. Any holder of Old Notes using the Exchange Offer
to participate in a distribution of the New Notes (i) cannot rely on the
position of the staff of the Securities and Exchange Commission (the
"Commission") enunciated in its interpretive letter with respect to Exxon
Capital Holdings Corporation (available May 13, 1988) or similar letters and
(ii) must comply with the registration and prospectus requirements of the
Securities Act in connection with a secondary resale transaction.

     If the undersigned is not a broker-dealer, the undersigned represents that
it is not engaged in, and does not intend to engage in, a distribution of New
Notes. If the undersigned is a broker-dealer that will receive New Notes for its
own account in exchange for Old Notes that were acquired as a result of market-
making activities or other trading activities, it acknowledges that it will
deliver a prospectus in connection with any resale of such New Notes, however,
by so acknowledging and by delivering a prospectus, the undersigned will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act. A broker-dealer may not participate in the Exchange Offer with respect to
Old Notes acquired other than as a result of market-making activities or other
trading activities.

     All authority herein conferred or agreed to be conferred shall survive the
death or incapacity of the undersigned and every obligation of the undersigned
hereunder shall be binding upon the heirs, personal representatives, successors
and assigns of the undersigned. Tendered Old Notes may be withdrawn at any time
prior to the Expiration Date in accordance with the terms of this Letter of
Transmittal. See Instruction 2.

     Certificates for all New Notes delivered in exchange for tendered Old Notes
and any Old Notes delivered herewith but not exchanged, and registered in the
name of the undersigned, shall be delivered to the undersigned at the address
shown below the signature of the undersigned.

                                 INSTRUCTIONS
        FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

1.   DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES.

A holder of Old Notes may tender the same by (i) properly completing and signing
this Letter of Transmittal or a facsimile hereof (all references in the
Prospectus to the Letter of Transmittal shall be deemed to include a facsimile
thereof) and delivering the same, together with the certificate or certificates
representing the Old Notes being tendered and any required signature guarantees
and any other document required by this Letter of Transmittal, to the Exchange
Agent at its address set forth above on or prior to the Expiration Date (or
complying with the procedure for book-entry transfer described below) or (ii)
complying with the guaranteed delivery procedures described below.

     THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, THE OLD NOTES AND ANY
OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDER, AND EXCEPT
AS OTHERWISE PROVIDED BELOW, THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY
RECEIVED OR CONFIRMED BY THE EXCHANGE AGENT. IF SUCH DELIVERY IS BY MAIL, IT IS
SUGGESTED THAT REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED,
BE USED. IN ALL CASES SUFFICIENT TIME SHOULD BE ALLOWED TO PERMIT TIMELY
DELIVERY. NO OLD NOTES OR LETTERS OF TRANSMITTAL SHOULD BE SENT TO THE COMPANY.

     If tendered Old Notes are registered in the name of the signer of the
Letter of Transmittal and the New Notes to be issued in exchange therefor are to
be issued (and any untendered Old Notes are to be reissued) in the name of the
registered holder (which term, for the purposes described herein, shall include
any participant in The Depository Trust Company (also referred to as a "book-
entry transfer facility") whose name appears on a security listing as the owner
of Old Notes), the signature of such signer need not be guaranteed. In any other
case, the tendered Old Notes must be endorsed or accompanied by written
instruments of transfer in form satisfactory to the Company and duly executed by
the registered holder, and the signature on the endorsement or instrument of
transfer must be guaranteed by a bank, broker, dealer, credit union, savings
association, clearing agency or other institution (each an "Eligible
Institution") that is a member of a recognized signature guarantee medallion
program within the meaning of Rule 17Ad-15 under the Securities Exchange Act of
1934, as amended. If the New Notes and/or Old Notes not exchanged are to be
delivered to an address other than that of the registered holder appearing on
the note register for the Old Notes, the signature on the Letter of Transmittal
must be guaranteed by an Eligible Institution.

     The Exchange Agent will make a request within two business days after the
date of receipt of this Prospectus to establish accounts with respect to the Old
Notes at the book-entry transfer facility for the purpose of facilitating the
Exchange Offer, and subject to the establishment thereof, any financial
institution that is a participant in the book-entry transfer facility's system
may make book-entry delivery of Old Notes by causing such book-entry transfer
facility to transfer such Old Notes into the Exchange Agent's account with
respect to the Old Notes in accordance with the book-entry transfer facility's
procedures for such transfer. Although delivery of Old Notes may be effected
through book-entry transfer into the Exchange Agent's account at the book-entry
transfer facility, an appropriate Letter of Transmittal with any required
signature guarantee and all other required documents must in each case be
transmitted to and received or confirmed by the Exchange Agent on or prior to
the Expiration Date, or, if the guaranteed delivery procedures described below
are complied with, within the time period provided under such procedures.

     If a holder desires to accept the Exchange Offer and time will not permit a
Letter of Transmittal or Old Notes to reach the Exchange Agent before the
Expiration Date or the procedure for book-entry transfer cannot be completed on
a timely basis, a tender may be effected if the Exchange Agent has received on
or prior to the Expiration Date, a letter or facsimile transmission (receipt
confirmed by telephone and an original delivered by guaranteed overnight
courier) from an Eligible Institution setting forth the name and address of the
tendering holder, the names in which the Old Notes are registered and, if
possible, the certificate numbers of the Old Notes to be tendered, and stating
that the tender is being made thereby and guaranteeing that within three
business days after the Expiration Date, the Old Notes in proper form for
transfer (or a confirmation of book-entry transfer of such Old Notes into the
Exchange Agent's account at the book-entry transfer facility), will be delivered
by such Eligible Institution together with a properly completed and duly
executed Letter of Transmittal (and any other required documents). Unless Old
Notes being tendered by the above-described method are deposited with the
Exchange Agent within the time period set forth above (accompanied or preceded
by a properly completed Letter of Transmittal and any other required documents),
the Company may, at its option, reject the tender. Copies of the notice of
guaranteed delivery ("Notice of

                                       8


Guaranteed Delivery") which may be used by Eligible Institutions for the
purposes described in this paragraph are available from the Exchange Agent.

     A tender will be deemed to have been received as of the date when (i) the
tendering holder's properly completed and duly signed Letter of Transmittal
accompanied by the Old Notes (or a confirmation of book-entry transfer of such
Old Notes into the Exchange Agent's account at the book-entry transfer facility)
is received by the Exchange Agent, or (ii) a Notice of Guaranteed Delivery or
letter or facsimile transmission to similar effect (as provided above) from an
Eligible Institution is received by the Exchange Agent. Issuances of New Notes
in exchange for Old Notes tendered pursuant to a Notice of Guaranteed Delivery
or letter or facsimile transmission to similar effect (as provided above) by an
Eligible Institution will be made only against deposit of the Letter of
Transmittal (and any other required documents) and the tendered Old Notes.

     If the Letter of Transmittal is signed by a person or persons other than
the registered holder or holders of Old Notes, such Old Notes must be endorsed
or accompanied by appropriate powers of attorney, in either case signed exactly
as the name or names of the registered holder or holders appear on the Old
Notes.

     No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders, by execution of this Letter of Transmittal (or
facsimile thereof), shall waive any right to receive notice of the acceptance of
the Old Notes for exchange.

2.   PARTIAL TENDERS; WITHDRAWALS.

     If less than the entire principal amount of Old Notes evidenced by a
submitted certificate is tendered, the tendering holder should fill in the
principal amount tendered in the box entitled "Principal Amount Tendered." A
newly issued certificate for the principal amount of Old Notes submitted but not
tendered will be sent to such holder as soon as practicable after the Expiration
Date. All Old Notes delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise clearly indicated.

     For a withdrawal to be effective, a written notice of withdrawal sent by
facsimile transmission (receipt confirmed by telephone) or letter must be
received by the Exchange Agent at the address set forth herein prior to the
Expiration Date. Any such notice of withdrawal must (i) specify the name of the
person having tendered the Old Notes to be withdrawn (the "Depositor"), (ii)
identify the Old Notes to be withdrawn (including the certificate number or
numbers and principal amount of such Old Notes), (iii) specify the principal
amount of Old Notes to be withdrawn, (iv) include a statement that such holder
is withdrawing his election to have such Old Notes exchanged, (v) be signed by
the holder in the same manner as the original signature on the Letter of
Transmittal by which such Old Notes were tendered or as otherwise described
above (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee under the Indenture
register the transfer of such Old Notes into the name of the person withdrawing
the tender and (vi) specify the name in which any such Old Notes are to be
registered, if different from that of the Depositor. The Exchange Agent will
return the properly withdrawn Old Notes promptly following receipt of notice of
withdrawal. If Old Notes have been tendered pursuant to the procedure for book-
entry transfer, any notice of withdrawal must specify the name and number of the
account at the book-entry transfer facility to be credited with the withdrawn
Old Notes or otherwise comply with the book-entry transfer facility procedure.
All questions as to the validity of notices of withdrawals, including time of
receipt, will be determined by the Company and such determination will be final
and binding on all parties.

     Any Old Notes so withdrawn will be deemed not to have been validly tendered
for exchange for purposes of the Exchange Offer. Any Old Notes which have been
tendered for exchange but which are not exchanged for any reason will be
returned to the holder thereof without cost to such holder (or, in the case of
Old Notes tendered by book-entry transfer into the Exchange Agent's account at
the book-entry transfer facility pursuant to the book-entry transfer procedures
described above, such Old Notes will be credited to an account with such book-
entry transfer facility specified by the holder) as soon as practicable after
withdrawal, rejection of tender or termination of the Exchange Offer. Properly
withdrawn Old Notes may be retendered by following one of the procedures
described under the caption "Procedures for Tendering Old Notes" in the
Prospectus at any time on or prior to the Expiration Date.

3.   SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND
     ENDORSEMENTS; GUARANTEE OF SIGNATURES.

Old Notes tendered hereby, the signature must correspond with the name(s) as

     If any of the Old Notes tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.

     If a number of Old Notes registered in different names are tendered, it

                           IMPORTANT TAX INFORMATION

     Under U.S. Federal income tax law, a holder of Old Notes whose Old Notes
are accepted for exchange may be subject to backup withholding unless the holder
provides The Bank of New York (as payor) (the "Paying Agent"), through the
Exchange Agent, with either (i) such holder's correct taxpayer identification
number ("TIN") on Substitute Form W-9 attached hereto, certifying that the TIN
provided on Substitute Form W-9 is correct (or that such holder of Old Notes is
awaiting a TIN) and that (A) the holder of Old Notes has not been notified by
the Internal Revenue Service that he or she is subject to backup withholding as
a result of a failure to report all interest or dividends or (B) the Internal
Revenue Service has notified the holder of Old Notes that he or she is no longer
subject to backup withholding; or (ii) an adequate basis for exemption from
backup withholding. If such holder of Old Notes is an individual, the TIN is
such holder's social security number. If the Paying Agent is not provided with
the correct taxpayer identification number, the holder of Old Notes may be
subject to certain penalties imposed by the Internal Revenue Service.

     Certain holders of Old Notes (including, among others, all corporations and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements. Exempt holders of Old Notes should indicate their exempt
status on Substitute Form W-9. In order for a foreign individual to qualify as
an exempt recipient, the holder must submit a Form W-8, signed under penalties
of perjury, attesting to that individual's exempt status. A Form W-8 can be
obtained from the Paying Agent. See the enclosed "Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9" for more instructions.

     If backup withholding applies, the Paying Agent is required to withhold 31%
of any such payments made to the holder of Old Notes or other payee. Backup
withholding is not an additional tax. Rather, the tax liability of persons
subject to backup withholding will be reduced by the amount of tax withheld. If
withholding results in an overpayment of taxes, a refund may be obtained from
the Internal Revenue Service.

     The box in Part 3 of the Substitute Form W-9 may be checked if the
surrendering holder of Old Notes has not been issued a TIN and has applied for a
TIN or intends to apply for a TIN in the near future. If the box in Part 3 is
checked, the holder of Old Notes or other payee must also complete the
Certificate of Awaiting Taxpayer Identification Number below in order to avoid
backup withholding . Notwithstanding that the box in Part 3 is checked and the
Certificate of Awaiting Taxpayer Identification Number is completed, the

                                      11


Paying Agent will withhold 31% of all payments made prior to the time a properly
certified TIN is provided to the Paying Agent.

     The holder of Old Notes is required to give the Paying Agent the TIN (e.g.,
social security number or employer identification number) of the record owner of
the Old Notes. If the Old Notes are in more than one name or are not in the name
of the actual owner, consult the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for additional guidance
on which number to report.
