Delphi Lateral Arm P/N:TC4687
Keep your BMW's rear suspension tracking true with the Delphi Lateral Arm TC8845. This rear left lower rearward lateral arm drops in as a direct-fit replacement for the 2018-2024 BMW X3 and 2019-2025 BMW X4 (all engines), linking the rear wheel carrier to the chassis to locate the wheel and control side-to-side movement while allowing the suspension to travel over bumps.
Worn bushings or a bent arm can show up as clunking or knocking from the rear, imprecise handling, or uneven tire wear. If a failed lateral arm is the cause, this replaces it — diagnose the source first, and have the wheel alignment checked after installation. This listing is for one arm for the rear left lower rearward position; each side uses its own part. Country of origin: Turkey.
