Delphi control arm engineering comes to your BMW's rear suspension with the Delphi Suspension Control Arm and Ball Joint Assembly (TC2954). It installs as a direct-fit replacement for the rear left position on a wide range of BMW cars, including the 2008-2010 BMW 528i and 2008-2010 BMW 535i, locating the wheel while the integrated ball joint allows the controlled movement your suspension and steering need.
- OE-validated testing: Delphi applies its OE expertise to the aftermarket line, testing parts below -40°C and above 120°C and through 720 hours of salt spray, with dimensional and material analysis for close OE-to-aftermarket compatibility.
- Inspected to match OE: Each control arm undergoes 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
- Precision ball stud: The ball studs are machined to micron tolerances for durability and smooth joint operation.
- Robot-welded, corrosion-protected: Robot welding gives consistent quality, and anti-corrosion protection is applied to each part for corrosion prevention and enhanced appearance.
Worn suspension components can show up as clunking or knocking over bumps, loose or wandering steering, and uneven tire wear; if a failed rear left control arm or its ball joint is the cause, this assembly replaces it. Inspect the matching side and related suspension parts, and have an alignment performed after installation.

Frequently Asked Questions
Is TC2954 the right BMW 528i control arm for a 2008-2010 BMW 528i?
Yes, TC2954 is a direct-fit replacement for the rear left position on the 2008-2010 BMW 528i, plus the 2009-2010 BMW 528i xDrive and many other BMW models. Check the "Vehicles it fits" section to confirm your year and model.
What position on the vehicle does TC2954 cover?
It is cataloged for the rear left suspension position. Confirm the exact corner against the "Vehicles it fits" section for your specific BMW.
What are the signs my control arm or ball joint needs replacing?
Common signs include clunking or knocking over bumps, loose or wandering steering, and uneven tire wear. Have the cause diagnosed, since these symptoms can come from other suspension parts too.
Is this a complete control arm and ball joint assembly?
Yes, TC2954 combines the control arm with an integrated ball joint whose ball stud is machined to micron tolerances, so you replace both as a single unit.
What testing does this control arm go through?
Delphi validates its parts with 100% crack and ultrasonic flaw detection, temperature testing from below -40°C to over 120°C, and 720 hours of salt spray for OE-level compatibility.
