- Front end service tool set built with robust 45# steel for high strength and deformation resistance, able to withstand high intensity extrusion. The forcing bolts have a black oxide finish to resist rust. Grease the bolts before use for smooth operation and thread protection, and grease again after use for better preservation. - This ball joint puller kit includes 1x ball joint separator, 1x tie rod end and ball joint remover, 1x conical pitman arm puller, 1x pitman arm and tie rod end puller, 1x pitman arm puller, and all 5 tools are organized in a red blow molding case for easy storage and transport. The tools use C-shape, jaw shape and teardrop shape designs to seat on the ball joint position tightly and provide effective grip to fix the pullers. - To use, select the compatible puller for your ball joint, insert the puller into the ball joint opening, align the bolt with the ball joint, and turn the bolt with the appropriate size ratchet wrench to squeeze the ball joint out. These ball joint pullers can easily remove stubborn ball joints, pitman arms, idler arms, tie rod ends, steering linkages and steering boxes on the front suspension and steering system, without damaging boots, sleeves or other parts.
