REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To ArvinMeritor, Inc., Hourly Employees Savings Plan and Participants:

We have audited the accompanying statements of net assets available for benefits
of ArvinMeritor, Inc. Hourly Employees Savings (the "Plan") as of December 31,
2003 and 2002 and the related statement of changes in net assets available for
benefits for the year ended December 31, 2003. These financial statements are
the responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of December 31,
2003 and 2002 and the changes in net assets available for benefits for the year
ended December 31, 2003 in conformity with accounting principles generally
accepted in the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The accompanying supplemental schedules,
"Form 5500, Part IV, Schedule H, Line 4i - Schedule of Assets (Held at End of
Year) and Line 4j - Schedule of Reportable Transactions", as of December 31,
2003 are presented for the purpose of additional analysis and are not a required
part of the basic financial statements, but are supplementary information
required by the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974. The
supplemental schedules are the responsibility of the Plan's management. Such
supplemental schedules have been subjected to the auditing procedures applied in
our audits of the basic financial statements and, in our opinion, are fairly
stated in all material respects when considered in relation to the basic
financial statements taken as a whole.

HOURLY EMPLOYEES SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 2003 AND 2002

1. DESCRIPTION OF THE PLAN

      The following general description of the ArvinMeritor, Inc., Hourly
Employees Savings Plan (the "Plan") is provided for general information purposes
only. Participants should refer to the Plan document for complete information.

      General - The Plan is a defined contribution retirement savings plan
covering all eligible hourly employees of ArvinMeritor, Inc (the "Company"). The
Plan is administered by the Company's Employee Benefit Plan Committee and the
Plan Administrator. The trustee for the Plan assets is T. Rowe Price Trust
Company. The Plan is subject to the provisions of the Employee Retirement Income
Security Act of 1974.

      Effective October 1, 2002, the employer matching account held under the
Plan was converted into an employee stock ownership plan (ESOP). As a result,
when participants accounts receive cash dividends on ArvinMeritor stock they
have the option of reinvesting the dividend in ArvinMeritor stock or receiving
the dividend as a cash distribution. In addition, the conversion to an ESOP
allows participants who have attained either age 55 with 10 years of vesting
service or age 60, the right to transfer funds out of company stock and into one
of the other investment options under the Plan.

      Effective January 1, 2002 the plan was amended to allow participants who
are over age 50 by the end of the plan year to make additional pre-tax
contributions up to the limits prescribed under recent changes to the Internal
Revenue Code.

      On April 1, 2003, total assets related to Roll Coater Retirement and
Savings Plan for Bargining Unit Associates of $1,756,959 were transferred into
the Plan, in connection with a merger of the plans. These amounts have been
included in net transfers on the Statement of Changes in Net Assets Available
for Benefits.

      Effective May 1, 2003, hourly employees of the Kenton, Ohio facility
became eligible for participation in the Plan.

      Contributions and Vesting - Eligible employees may elect to contribute up
to 20% of pay, both before and after tax or a combination of both. The
participants are immediately eligible for company matching contributions.
Matching contributions and participant contributions are immediately vested. The
Company's match calculation varies by location within the Plan. All Company
match contributions are payable in Company stock, except for a joint venture
whereby the contribution match for employees is made in cash.

      Plan Withdrawals - Amounts contributed may be withdrawn by, or distributed
to, a participant only upon (1) termination of employment or (2) attaining the
age of 59 1/2. Withdrawals prior to attaining age 59 1/2 are not permitted
except in the event of retirement,


                                       4


disability or as a hardship distribution. Certain income tax penalities may
apply to withdrawals or distributions prior to age 59 1/2.

      Payment of Benefits - On termination of service due to death, disability,
retirement or other, a participant generally receives an amount equal to the
value of the participant's vested interest in their account in a lump-sum
amount. For termination of service due to other reasons, a participant may
receive the value of the vested interest in their account as a lump-sum
distribution.

      Loans to Participants - A participant may obtain a loan in an amount as
defined by the Plan document (not less than $1,000 and not greater than the
lesser of $50,000 or 50% of the participant's vested account balance) from the
balance of his/her account. Interest is charged at a rate that is comparable to
rates charged by commercial lending institutions. The loans are repaid through
payroll deductions generally over periods not to exceed 60 months. Payments of
principal and interest are reinvested into the participants' current investment
options. Participants may have only one outstanding loan at a time.

      Participant Accounts - Each participant's account is credited with the
participant's contribution and an allocation of the Company's contribution and
Plan earnings and charged with an allocation of administrative expenses.
Allocations are based on a participant's earnings or account balances as
defined. The benefit to which a participant is entitled is the benefit that can
be provided from the participant's vested account.

      Plan Termination - Although the Company has not expressed any intent to
terminate the Plan, it reserves the right to do so at any time.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Basis of Accounting - The financial statements of the Plan are prepared
under the accrual method of accounting.

      Investment Valuation - Investments, other than benefit-responsive
investment contracts, are stated at fair value as measured by readily available
market prices. The T. Rowe Price Stable Value Common Trust Fund is comprised of
individual investment contracts, including synthetic investment contracts and
are stated at contract value. The investment contracts are nontransferable, but
provide for benefit-responsive withdrawals by plan participants at contract
value. Benefit-responsive withdrawals are provided for on a proportional basis
by the issuers of the investment contracts. The trustee's valuation committee
primarily considers factors such as the benefit responsiveness of the investment
contract and the ability of the parties to the investment contract to perform in
accordance with the terms of the contract. Generally, contract value
approximates fair value (contributions made plus interest accrued at the
contract rate, less withdrawals and fees). If, however, an event has occurred
that may impair the ability of the contract issuer to perform in accordance with
the contract terms, fair value may be less than contract value.

      Security Transactions and Investment Income - Purchases and sales of
securities are reported on trade date basis. Dividends are recorded on the
ex-dividend date and interest income is recorded on the accrual basis.


                                        5


      Plan Expenses - Administrative expenses of the Plan are paid by either the
Company or the Plan, as provided by the Plan document.

      Use of Estimates - The preparation of financial statements in conformity
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and changes therein, and disclosure of
contingent assets and liabilities. Actual results could differ from those
estimates. The Plan utilizes various investments, which are exposed to various
risks such as interest rate, foreign currency, credit, and overall market
volatility. Due to the level of risk associated with certain investment
securities, it is reasonably possible that changes in the values of investment
securities will occur in the near term and that such changes could materially
affect the amounts reported in the Statement of Net Assets Available for
Benefits.

3. INVESTMENTS

5. TAX STATUS

      The Internal Revenue Service determined and informed the Company by a
letter dated July 15, 2002, that the Plan was designed in accordance with
applicable sections of the Internal Revenue Code ("IRC"). The Plan has been
amended since receiving the determination letter, however, the Company and the
Plan administrator believe that the Plan is designed and is currently being
operated in compliance with the applicable sections of the Code and as a result,
no provision for income taxes has been included in the Plan's Financial
Statements.

6. RELATED PARTY TRANSACTIONS

      Plan investments are shares of mutual funds managed by T. Rowe Price. T.
Rowe Price is the trustee as defined by the Plan and, therefore, these
transactions qualify as party-in-interest transactions.

7. SUBSEQUENT EVENT

      Effective January 1, 2004, the Company added five new retirement fund
options to the Plan. The new retirement Fund options include the following
funds: T. Rowe Price Retirement Income Fund, T. Rowe Price Retirement 2010 Fund,
T. Rowe Price Retirement 2020 Fund, T. Rowe Price Retirement 2030 Fund and T.
Rowe Price Retirement 2040 Fund. These new options are a fund of funds which
