  Q: How to replace the universal joint with a nylon injected ring on Chevrolet Astro?

  A: You need the j 9522-3 u joint bearing separator and j 9522-5 u joint bearing spacer remover to replace the Universal Joint with a nylon injected ring. Only clamp one yoke and position the shaft horizontally to replace the Universal Joint without damaging the slip surface or shaft deformation. Place the shaft on the press with its ends resting flat in position. Apply marks on the propeller shaft to show which side fits at the transfer case end or rear axle and front axle end. Fix the Universal Joint onto the lower yoke so that this smaller part rests securely on the 30 mm (1/8 inch) socket. The u joint bearing separator tool j 9522-3 can separate the plastic retainer ring to let you press the lower bearing cup out from the yoke ear. Push the u joint bearing spacer remover (J 9522-5) between the seal and bearing cup of the cross. Then push the bearing cup out. Turn the propeller shaft to push the other bearing cup out while disassembling the cross from the yoke and taking off all Universal Joint pieces. When you replace the rear axle's front Universal Joint you will follow same cup bearing removal steps inside the Slip Yoke. Search for broken plastic inside retaining ring grooves and damaged parts in bearing cup bores before cleaning away sheared plastic scraps from these areas. Before installation coat each needle bearing in new Universal Joint journals with thin chassis grease and take out the bearing from the opposite journal part. Turn the yoke ear down and insert the cross into the half-bearing cup so that the trunnion moves without restrictions. Place the bearing cup into the yoke until it meets the surface and set the other bearing cup in place making sure trunnion parts match. Halt the pressing process to inspect the joint parts. Insert the bearing retainer into each yoke section until clear space appears at its groove then press it firmly into position using chassis grease when needed. Strike the yoke gently with a dead blow hammer when the retainer fails to engage. Finally, install the propeller shaft.
