The AGM Uni-Ball Tool lets you replace worn uni-balls, also known as spherical bearings, without removing the suspension or steering component from the vehicle. Instead of pulling large components off the car, fighting them in a shop press, or beating on expensive parts with a hammer and punch, the Uni-Ball Tool gives you a compact, controlled way to press the worn bearing out and install the new one. After removing the retaining C-clip, the tool uses a piston, cup, ACME-thread bolt, load-bearing washer, and nut to pull the worn uni-ball out of the component and into the receiving cup. To install the new uni-ball, flip the cup and piston positions and press the replacement bearing back into place. Built for race teams, fabricators, repair shops, and serious DIYers, each Uni-Ball Tool is made from high-strength steel for repeated service in the shop, garage, or alongside the race course.
