Keep the front suspension tight and precisely located with the Delphi control arm and Ball Joint Assembly (P/N: TC5524). This front left assembly combines the control arm and its integral ball joint into one direct-fit unit for the 2001-2005 BMW 325xi and 2001-2005 BMW 330xi — see the Buyer's Guide tab for engine-level fitment. It locates the wheel, allows suspension travel, and provides the pivot for steering and ride motion.
Signs the original may need replacing include steering wander, uneven tire wear, and clunking or knocking from the front suspension over bumps. This is a front left assembly, sold individually; replacing both sides together is recommended.
