            STATEMENT UNDER OATH OF PRINCIPAL EXECUTIVE OFFICER AND
                PRINCIPAL FINANCIAL OFFICER REGARDING FACTS AND
                 CIRCUMSTANCES RELATING TO EXCHANGE ACT FILINGS


         I, Larry D. Yost, Chairman of the Board and Chief Executive Officer of
ArvinMeritor, Inc., state and attest that:

         (1)      To the best of my knowledge, based upon a review of the
                  covered reports of ArvinMeritor, Inc., and except as corrected
                  or supplemented in a subsequent covered report:

                  -      no covered report contained an untrue statement of a
                         material fact as of the end of the period covered by
                         such report (or in the case of a report on Form 8-K or
                         definitive proxy materials, as of the date on which it
                         was filed); and

                  -      no covered report omitted to state a material fact
                         necessary to make the statements in the covered report,
                         in light of the circumstances under which they were
                         made, not misleading as of the end of the period
                         covered by such report (or in the case of a report on
                         Form 8-K or definitive proxy materials, as of the date
                         on which it was filed).

         (2)      I have reviewed the contents of this statement with
                  ArvinMeritor, Inc.'s audit committee.

         (3)      In this statement under oath, each of the following, if filed
                  on or before the date of this statement, is a "covered
                  report":

                  -      ArvinMeritor, Inc.'s Annual Report on Form 10-K for the
                         fiscal year ended September 30, 2001;

                  -      all reports on Form 10-Q, all reports on Form 8-K and
                         all definitive proxy materials of ArvinMeritor, Inc.
                         filed with the Securities and Exchange Commission
                         subsequent to the filing of the Form 10-K identified
                         above; and

                  -      any amendments to any of the foregoing.
