Cognito 11-25 Chevrolet Silverado 2500 Alpha Ball Joint w/ Press-In Style Upper Control ArmWith a heavy duty design, this is still a joint and thus still a wear item. Being a press in ball joint, you would think it will be a pain to freshen up, but the Alpha Ball Joint is rebuildable and simple to do with a rebuild kit. The ease of rebuilding stems from the corrosion resistant zinc plated housing of the ball joint remaining in the control arm. The ball joint can be rebuilt in the control arm without even having to remove the control arm
