Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC1346
Delphi TC7983 front left lower control arm with ball joint for the 2016-2017 Subaru Crosstrek and other vehicles links the wheel to the chassis and carries the ball joint that lets it pivot. It is also called a control arm and ball joint assembly.
A clunk over bumps or uneven tire wear can mean a worn arm or ball joint, though other suspension parts can produce them too. With the engine off, look at the tires and the arm for wear or cracks; a shop can test joint play. Control arms are normally replaced as a pair, but this listing is one front left arm; the front right is a separate part.
This control arm fits the 2016-2017 Subaru Crosstrek and the 2013-2015 Subaru XV Crosstrek, and each takes one in the front left lower position.
