  Q: How to replace the front CV Boot and CV Joint on the drive axle's inner joint on Chevrolet Astro?

  A: The replacement of the front drive axle's drive shaft inner joint and boot requires specific tools: you will need snap ring pliers (J 8059) together with the small seal clamp tool (J 35910) and large seal clamp tool (J 35566). Snap ring pliers (J 8059), small seal clamp tool (J 35910), and large seal clamp tool (J 35566). Use side cutters to unlock the large boot clamp from the tripot boot before separating the tripot housing and bushing from the halfshaft bar. Always clean grease from the tripot assembly roller bearings and housing. Apply 320 grit 3m cloth to degrease the housing and bushing before wiping down the transmission booting surface and letting everything dry. Remove the small boot clamp from the halfshaft bar end of the tripot boot while gently handling the tripot spider assembly to stop the tripot balls and needle rollers from separating. Insert the tripot boot onto the halfshaft bar before opening the spider spacer ring using the snap ring pliers. After positioning the spider spacer ring and tripot spider assembly on the halfshaft bar you will reach the retaining ring which should be taken out with the other components. Clean the halfshaft bar with a wire brush until all rust in the boot mounting area disappears while checking the needle rollers and needle bearings and trunnion for any signs of wear or damage. When assembling the joint boot clamp must be placed on the small end of the joint boot before installing the tripot boot and small boot clamp onto the halfshaft bar using the small seal clamp tool and breaker bar with torque wrench set to 136 nm (100 ft./lbs.). Assemble the joint so the convolute retainer maintains its correct position which prevents boot damage. Assemble the convolute retainer first before inserting the first spacer ring and tripot spider assembly making sure the counterbore faces the halfshaft bar end. After installing the second spacer ring in the halfshaft bar groove push the spider assembly back to expose the counterbore that covers the retaining ring. After seating the spider spacer ring completely in the groove, apply pre-measured kit grease to both the tripot boot and housing before placing the large retaining clamp onto the boot. Food the housing over the spider assembly before attaching the boot to the housing while verifying inboard stroke position. Secure the large retaining clamp and boot to the housing with the large seal clamp tool at 176 nm (130 ft. Lbs.) torque while confirming clamp ear gap measurement. After completing the process remove the convolute retainer from the boot.
