Restore tight, controlled steering and smooth suspension travel with the Delphi ball joint TC5284, a direct-fit front suspension ball joint for the 2011-2015 BMW X3 and 2015-2018 BMW X4. A ball joint links the control arm to the steering knuckle, letting the suspension move up and down while the wheel steers — worn units can bring clunking over bumps, loose or wandering steering, and uneven tire wear, all signs this part may need replacing. See the Buyer's Guide tab for engine-level fitment.
Delphi applies its OE expertise to its aftermarket steering portfolio, with parts tested to withstand temperatures below -40°C and over 120°C plus 720 hours of salt spray, and extensive dimensional and material analysis for compatibility between the OE and aftermarket part.
