Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS30121
Locate the front wheel and let it pivot through every steering and suspension movement with the Mevotech Supreme control arm CMS101547, a front right (passenger-side) lower control arm and ball joint assembly engineered in-house with application-specific upgrades. It installs as a direct-fit replacement for the 2016-2024 BMW X1, 2018-2024 BMW X2, 2016-2024 MINI Cooper Clubman, 2017-2024 MINI Cooper Countryman, 2021-2024 BMW 228i Gran Coupe, 2020-2024 BMW 228i xDrive Gran Coupe and 2020-2024 BMW M235i xDrive Gran Coupe — see the Buyer's Guide tab for the full list and engine coverage.
Built for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks, this unit combines the arm and its ball joint into one bolt-in piece, so replacing it renews both at once. Searching for a BMW X1 lower arm, or the same part for the X2, MINI Cooper Clubman or Countryman? CMS101547 covers those applications. Sold individually as the front right lower unit; order the corresponding left-side arm to service both corners as a matched pair.

Is this a Bmw X1 control arm replacement?
Yes — CMS101547 is listed for the 2016-2024 BMW X1 as the front right lower arm, and also fits the X2, MINI Cooper Clubman and Countryman, plus select 228i and M235i models. Check the Buyer's Guide tab.
Which side and position is this Mevotech Supreme lower control arm?
It's the front right (passenger-side) lower control arm. Order the left-side unit separately if you're servicing both corners of the front suspension.
What does this control arm with ball joint do?
It locates the front wheel and lets it pivot through steering and suspension travel, with the ball joint providing the pivoting connection between the arm and the steering knuckle.
Does this Mevotech Supreme suspension control arm include the ball joint?
Yes. The ball joint is integrated into this one bolt-in assembly, so replacing the arm renews both the arm and the ball joint at the same time.
What are signs this part may need replacing?
Clunking or knocking over bumps, steering wander, looseness, or uneven tire wear can be signs. Have the cause diagnosed first, since these symptoms can have other sources.
