The ball joint is the pivot that links the upper control arm to the steering knuckle, which lets the suspension travel and the wheel steer. Mevotech engineers its Supreme Parts in-house, with application-specific upgrades aimed at durability and performance. It builds Supreme ball joints for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks. Its Labor Saver designs and hardware are intended to make installation quicker and easier.
- Superior toughness: sintered bearings are designed for longer-lasting performance.
- Hardware included: a part-specific castle nut and cotter pin secure the joint to the vehicle, and a 90-degree SAE grease fitting makes servicing simple.
- Fit and function: a thicker, stronger flange helps prevent deformation during installation.
- Tighter grip: knurling gives a snugger fit between connecting points and helps resist distortion and corrosion.
Signs that a ball joint may need replacing include clunking over bumps, wandering or loose steering, uneven tire wear and play in the joint. Diagnose the cause before replacing, and follow the vehicle service information for installation and torque specifications.
