Mevotech engineers its Supreme parts in-house, with application-specific upgrades aimed at added durability and performance. It builds its Supreme ball joints for high-usage passenger vehicles, SUVs and fleets. Across the line, Mevotech's Labor Saver™ designs, tools and hardware are intended to make installations faster and easier.
As a suspension ball joint, it acts as a pivot point between the steering knuckle and the suspension, which lets the wheel steer and move through suspension travel. Signs a ball joint may need replacing include clunking over bumps, loose or wandering steering, excessive play in the joint and uneven tire wear. Other components can cause the same symptoms, so diagnose the cause before replacing.
