The Medium Duty U-Joint Puller delivers the brute strength needed to remove even the most seized U-joints in just minutes—without hammering, torching, or risky vice-and-socket methods. Ideal for servicing medium-duty trucks, school buses, farm vehicles, and light industrial equipment, this tool is built to handle the toughest jobs while protecting surrounding components. Precision-cast from high-grade steel, each puller is designed for a universal fit and unmatched durability. Proprietary manufacturing and treatment processes ensure the threads hold strong, even under extreme conditions common to seized U-joint applications. Applications: Compatible with Class 3–5 trucks and equipment including Ram 3500/5500, Chevrolet 3500/5500, Ford F-350/550, Isuzu NPR, and more. Fits U-joints with bearing cups from 1.25″ to 1.7″ O.D. Compatible with Spicer SPL 90 & 100 Series. Notes: Not compatible with Double Cardan joints. For those applications, use the Automotive C-Frame Socket Press. Use caution when working with flange-style yokes if bearing cups are severely seized.
