  Q: How to replace the universal joints (Nylon Injected Ring Type) on GMC C3500?

  A: To install the new universal joints, set the propeller shaft on a press table, make marks for connecting to the transmission and rear axle and then remove the shaft to measure the distance between the joints. Rest the lower ear of the Universal Joint in a (30 mm) 1 1/8 inch socket. Shear the plastic retaining ring on the bearing cup using the j9522-3 and push the lower bearing cup out of the yoke ear. Should the bearing cup remain attached, remove the cross and put j9522-5 between the seal and the bearing cup. Twist the propeller shaft counterclockwise to eject the bearing cup on the other side and disassemble the cross from the yoke; throw out all the Universal Joint parts since they cannot be put back together. Get rid of all the loose parts from the yoke and if getting a new front Universal Joint, eliminate the bearing cups from the Slip Yoke in the same manner. Make sure the grooves and bores of the retaining rings and bearings are free of anything that could hinder new bearing placement, then clear out the bearing cup grooves of sheared plastic. Before installation, unclip the bearing cups from the universal joints, grease the needle bearings and put one bearing cup halfway into the yoke's side. Align the yoke ear at a downward angle, place the cross to lower its trunnion into the bearing cup and press the bearing cup against the yoke ear. Put on the top bearing cup about halfway and make sure the trunnions are aligned, then press the cup into the yoke and check if the trunnions still move smoothly. Press the bearing until it is completely inside the yoke and stop if there is any tightening, since this could mean the parts are not perfectly aligned. After that, insert the bearing retainer into the groove and keep pressing until both retainers click into their places with some help from the chassis grease.
