Mevotech Supreme CMS501277 front right lower control arm with ball joint for the 2020-2024 Cadillac CT4 and other vehicles connects the front right steering knuckle to the chassis and pivots on its press-in ball joint. As a control arm and ball joint assembly, it comes with rubber bushings and is built to meet OE specifications or better.
A clunk over bumps, loose or wandering steering or uneven front tire wear can mean a worn lower control arm or ball joint. Other suspension parts can give similar signs, so with the engine off, first look for cracked or split rubber at the bushings and ball joint, and leave play testing to a shop.
It fits as a control arm for the 2020-2024 Cadillac CT4, the 2013-2019 Cadillac ATS and the 2017 Cadillac CTS. This listing is one arm for the front right, which takes one; the front left is a separate part ordered on its own, and the two sides are normally replaced together.
