Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMK80354
Restore a tight, controlled front end with the Mevotech Supreme Suspension Control Arm and Ball Joint Assembly CMS501157. This front left lower control arm ships with the ball joint pre-assembled and drops in as a direct-fit replacement for the 2003-2005 Saturn Ion (see the Buyer's Guide tab for engine-level detail). It locates the lower suspension, pivots with the wheel travel, and provides the steering-knuckle pivot point through its integrated ball joint.
Signs this part may need replacing include clunking over the front suspension on acceleration or braking, uneven tire wear, wandering steering, or a loose, imprecise feel. If a worn front left lower control arm or ball joint is the cause, this assembly replaces both.
