Delphi Suspension Control Arm P/N:TC8623
Delphi TC9041 front left lower control arm for the 2018 Buick LaCrosse links the front left wheel to the body and lets the suspension move. It is also listed as a suspension control arm.
A clunk over bumps, uneven front tire wear or a wandering feel in the steering can mean a lower control arm or its ball joint is worn. These signs alone do not prove the arm is at fault, since a worn sway bar link can make a similar noise.
This control arm is a direct-fit replacement for the 2018 Buick LaCrosse. This listing is one arm for the front left; the front right is a separate part, and both sides are normally replaced together.
