Item 8.01.        Other Events.

         As described in Part I, Item 3. Legal Proceedings in the Annual Report
on Form 10-K of ArvinMeritor, Inc. ("ArvinMeritor" or the "company") for the
fiscal year ended October 2, 2005 ("Form 10-K"), three separate class action
lawsuits were filed in the United States District Court for the Eastern District
of Michigan ("District Court") against ArvinMeritor as a result of modifications
made by the company to its retiree health benefits. The lawsuits allege that the
changes breach the terms of various collective bargaining agreements entered
into with the United Auto Workers ("UAW") and the United Steel Workers at former
facilities that have either been closed or sold, and allege a companion claim
restating these claims and seeking to bring them under the Employee Retirement
Income Security Act of 1974.

         On December 22, 2005, the District Court issued an order granting a
motion by the UAW for a preliminary injunction. The order enjoins the company
from implementing the changes to retiree health benefits that had been scheduled
to become effective on January 1, 2006, and orders the company to reinstate and
resume paying the full cost of health benefits for the UAW retirees at the
levels existing prior to the changes implemented in 2003 and 2005. We are
currently studying the order and analyzing its impact on ArvinMeritor. (See the
information in the Form 10-K under the headings "- Overview" and "- Critical
Accounting Policies - Retiree Medical" in Part II, Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operations, and
Note 19 of the Notes to Consolidated Financial Statements in Part II, Item 8.
Financial Statements and Supplementary Data, for information with respect to the
changes made to the company's retiree health benefits and the related accounting
and financial impacts.) The company intends to file an appeal with the United
States Court of Appeals for the Sixth Circuit.
