Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC6664
Delphi TC7630 front left lower control arm with ball joint for the 2015-2022 Ford Mustang connects the steering knuckle to the frame. This control arm and ball joint assembly replaces the arm and the joint in one piece.
A clunk over bumps, wandering steering or uneven front tire wear can mean this arm or its ball joint is worn, though a worn sway bar end link or tie rod end can produce similar symptoms.
This is a direct-fit replacement for the 2015-2022 Ford Mustang, which takes one on the front left. The front right side is a separate part ordered separately, and the two sides are normally replaced together.
