If a SUSPENSIA control arm review pointed you here, the SUSPENSIA Control Arm and Ball Joint Assembly X21CJ0770 pairs the lower control arm with its ball joint in one direct-fit unit for the 1998-2003 Jaguar XJ8, 1998-2003 Jaguar Vanden Plas, and 1998-2003 Jaguar XJR. It installs in the front left lower rearward position, locating the wheel and letting the steering knuckle pivot through suspension travel.
This control arm and ball joint assembly combines the arm with its integrated ball joint, so worn pivot components are renewed together.
Signs this part may need replacing include clunking on acceleration or over bumps, imprecise steering, or a cracked ball-joint boot. Diagnose the cause before ordering to confirm the arm is the source. This listing covers one assembly for the driver-side lower rearward location.
