DETROIT -- An American Axle and Manufacturing Holdings Inc. spokeswoman said this weekend the auto parts supplier has reached a tentative agreement with the United Auto Workers that could end an 11-week strike.

Spokeswoman Renee Rogers said she doesn't have any details of the deal reached late Friday. It's not clear when the agreement will be presented to union members.

The walkout by about 3,600 workers at five factories had crippled truck and sport utility vehicle manufacturing at General Motors Corp.

The company makes axles, drive shafts and stabilizer bars for GM, Chrysler LLC, and other automakers.

GM was forced to partially or fully close more than 30 factories and lay off thousands of workers because of parts shortages. General Motors's Janesville Assembly has been running one shift a day, instead of the usual two, since the strike began.
