Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC1579
Delphi TC9161 front left lower control arm with ball joint for the 2011-2018 Volkswagen Jetta links the wheel to the body and lets it pivot. This control arm and ball joint assembly is sold as one arm.
A clunk over bumps, loose steering feel or uneven tire wear can mean the ball joint or arm is worn. A tired strut or other suspension parts can give similar symptoms, so first look the arm over with the engine off for cracks, bends and heavy rust.
This front left lower control arm is a direct-fit replacement for the 2011-2018 Volkswagen Jetta, which takes one on this side. The front right is a separate part, and both sides of the front axle are normally replaced at the same time.
