- Tested to withstand temperatures below -40 degrees C and over 120 degrees C, and exposed to 720 hours of salt spray
- 100% crack detection and ultrasonic flaw detection, so the materials match OE specifications
- Ball studs machined to micron tolerances for durability and smooth joint operation
- Robot welding for consistent performance and quality
- Anti-corrosion protection applied to each part
A worn control arm or ball joint can show up as a clunk over bumps, wandering steering or uneven tire wear, but worn bushings, shocks or alignment problems can produce those symptoms too. With the engine off, start by looking for a cracked or bent arm, a torn ball joint boot or heavy rust, and leave any further testing to a shop. This listing is one control arm and ball joint assembly, the left side is a separate part, and both sides are normally replaced together.
The arm is listed for a wide range of BMW models, including the 2019-2025 BMW X7 and the 2020-2025 BMW X6, and each takes one. If your BMW is not named here, look it up on the Buyer's Guide tab.
