This front left lower control arm and ball joint assembly is a direct-fit replacement for the 2017-2025 Cadillac XT5 and the 2017-2023 GMC Acadia (see the Buyer's Guide tab for full engine details).

Backed by Mevotech's extensive in-house and third-party durability testing. Sold individually — this listing covers the front left lower unit.

Does it include the ball joint?
Yes. It is a complete control arm and ball joint assembly, so the ball joint comes pre-installed in the arm — no separate joint to press in.
Is a grease fitting included?
Yes, an SAE grease fitting is included so the ball joint can be re-lubricated during service.
What are common signs this part needs replacing?
Clunking or knocking over bumps, loose or wandering steering, vibration, and uneven front tire wear. Have the cause diagnosed, since these symptoms can come from other suspension parts too.
