This suspension ball joint is the pivoting connection between the lower control arm and the steering knuckle, letting the front wheels steer while the suspension travels. Mevotech Supreme parts are engineered in-house with application-specific upgrades aimed at durability and performance for high-usage commercial vehicles, SUVs, fleets and working trucks.

• Superior toughness: sintered bearings for longer-lasting performance.
• Simple to service: includes a 90-degree SAE grease fitting.
• Exceptional fit: a thicker, stronger flange helps prevent deformation during installation.
• Tighter grip: knurling promotes a snugger fit between connecting points and helps resist distortion and corrosion.
• Faster fit: a part-specific locking nut is provided to speed up installation.

If a worn front lower ball joint is the cause of clunking, wander or uneven tire wear, this replaces it.
