U-Joint Puller is made of high-quality heavy-duty carbon steel, and its surface is black anodized to prevent rust and impact. Fits 1 to 1.25 inches (approximately 2.5 to 3.2 cm) U joint bearing cups, suitable for almost all 1-3 category trucks and machinery. The heavy-duty universal joint puller eliminates the danger of vise and sleeve or hammering, and will not damage the drive shaft, fork, joint or bearing seat. The design of an impact wrench can provide the greatest strength for drive disassembly, with a capacity of about 7 tons. If the bearing is difficult to disassemble, you can heat the bearing or add lubricating fluid around the bearing before dismounting.
