  Q: How to replace a universal joint on GMC Envoy?

  A: First support the propeller shaft horizontally by securing one yoke with a clamp while protecting the Slip Yoke sealing surface during this process. Use a gentle tap on the yoke followed by plier removal of the Universal Joint retaining ring. After securing the propeller shaft at proper level position on the press select the right socket format to maintain the Universal Joint area beyond the j 9522-3 (U-Joint Bearing Separator). Use the j 9522-3 (U-Joint Bearing Separator) with the press to remove the universal bearing from the yoke. Place the j 9522-5 (U-Joint Bearing Spacer Remover) onto the Universal Joint before using both tools alongside the press to fully remove it. Repetition of the procedure for separating the Universal Joint requires turning the propeller shaft before continuing with the second Universal Joint. A damaged Slip Yoke requires replacement together with a new Universal Joint. Then extract both items - Slip Yoke from the propeller shaft and retaining ring from the Slip Yoke. A combination of tools j 9522-3 (U-Joint Bearing Separator) and j 9522-5 (U-Joint Bearing Spacer Remover) with a press enables technicians to extract the universal bearing from the yoke while removing the spider from the Slip Yoke before thoroughly cleaning both components. Install universal bearings into the propeller shaft's yoke then position the Universal Joint spider until it reaches full seat depth before pressing it to the yoke's plane. First install the yoke retaining ring then turn the propeller shaft while you repeat these steps for its opposing universal bearing. Test the Universal Joint for free movement before installation. Slight tapping of the yoke helps position the bearing correctly against the retaining ring. Please install two more universal bearings before securing everything with electrical tape during propeller shaft assembly. When installing universal spiders in slip yokes personnel must first fully seat one spider before pressing the bearings into the yoke until it maintains a level position. After installing the retaining ring into the Slip Yoke users must rotate it before repeating the installation sequence for the other bearing. Consolidate by positioning the Slip Yoke inside the propeller shaft then center the universal spider within the bearing. Press the bearing into the yoke then install the retaining ring inside the propeller shaft yoke. Use a rotating motion on the propeller shaft to repeat the universal bearing installation while verifying free movement of the Universal Joint through careful yoke tapping if required.
