ITEM 5.  OTHER EVENTS AND REGULATION FD DISCLOSURE.

         As discussed under Item 2. "Management's Discussion and Analysis of
Financial Condition and Results of Operations - Liquidity" in ArvinMeritor's
Quarterly Report on Form 10-Q for the quarterly period ended March 30, 2003
(Form 10-Q), Standard & Poor's (S&P) placed ArvinMeritor on negative credit
watch in the second quarter of fiscal year 2003, indicating that ArvinMeritor's
credit rating was under review.

         On May 20, 2003, S&P lowered the rating for ArvinMeritor's long-term
debt and senior unsecured debt to BB+ from BBB- and withdrew the rating on
ArvinMeritor's short-term debt.

         As discussed in Note 14 of the Notes to Consolidated Financial
Statements in the Form 10-Q, ArvinMeritor has two unsecured credit facilities
maturing on June 27, 2005 that provide for up to $1.15 billion of revolving
borrowings. Borrowings under these facilities are subject to interest based on
quoted LIBOR rates plus a margin, and a facility fee, both of which are based on
ArvinMeritor's credit rating. As a result of the downgrading by S&P, the
applicable margin over the LIBOR rate increased to 115 basis points from 105
basis points, and the facility fee increased to 22.5 basis points from 20 basis
points. At March 31, 2003, ArvinMeritor had no borrowings outstanding under
these credit facilities.

         Pursuant to the requirements of the Securities Exchange Act of 1934,
