Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC3622
Delphi TC6331 front right lower control arm with ball joint for the 2008-2009 Chevrolet Trailblazer and other vehicles connects the wheel to the frame and moves with suspension travel. The ball joint is built into the arm, so this control arm and ball joint assembly replaces both in one piece.
A clunk over bumps, loose or wandering steering, or uneven tire wear can go with a worn lower arm or ball joint, though other suspension parts can produce similar symptoms. Before replacing it, look the arm over with the engine off for cracks, a torn ball joint boot or leaking grease, and leave play testing to a shop.
It fits as a control arm for the 2008-2009 Chevrolet Trailblazer, the 2008-2009 GMC Envoy and the 2008 Isuzu Ascender. This listing is one arm for the front right side, which takes one; the front left is a separate part, and the two sides are normally replaced together.
