Detailed Description

Mevotech Supreme Parts are engineered in-house with application-specific upgrades for durability and consistent performance in high-use passenger vehicles, SUVs, fleets, and working trucks.

Common Problems This Part Addresses

• Front-end clunking or popping from a worn upper control arm joint

• Uneven tire wear caused by loose or deteriorated suspension components
• Steering wander or reduced front-end stability
• Cracked bushings or damaged dust boot on the original assembly

Installation Notes and Tips

Confirm vehicle year, model, and front left upper position before installation. Inspect adjacent suspension parts, alignment settings, and fasteners during service. Because the assembly includes a threaded ball joint stud, castle nut, cotter pin, and mounting hardware, installation is streamlined compared with rebuilding the original arm. After replacement, a professional alignment is recommended.
