Quick facts
- Part: Delphi TC446 trailing arm
- Also called: suspension trailing arm
- Fits: 1989-1995 BMW 525i and other vehicles
- Position: Rear
- Condition: New
A clunk from the rear over bumps, uneven rear tire wear or a rear wheel that no longer holds its alignment can come from a worn trailing arm. These signs alone do not prove the arm is the problem, since a tired shock absorber can cause similar symptoms.

Both rear arms are normally replaced together, and this listing is one arm. The vehicles it fits include the 1989-1995 BMW 525i, which takes two, along with the 1994-1995 BMW 530i and the 1994-1995 BMW 540i. If your BMW is not named here, look it up in the Vehicles it fits section.
