• Q: How to replace the front wheel drive shaft inner CV joint and seal on 2002 GMC Envoy?

  A: Use side cutters to detach the boot clamp before starting the wheel drive shaft inner joint and seal exchange. A hand grinder should be used to cut through the swage ring while you carefully discard the tripot housing and trilobal tripot bushing from the halfshaft bar. After complete cleaning of the housing and spider assembly discard the tripot bushing. The transmission sealing surface should receive treatment using a 3M cloth with 320 grit abrasiveness or its equivalent to remove corrosion while the housing and spider assembly dries. The necessary manipulations for assembling the tripot spider require gentle movements to keep the tripot balls and needle rollers in place. Cut a piece of tripot boot to fit on the halfshaft bar until snap ring pliers (J 8059) apply the proper tension to the spacer rings so assembly removal can begin. Operate a wire brush to clean the halfshaft bar while you inspect all components for damage. Replace any broken parts with proper replacement items from the kit. First position the new swage clamp on the boot neck before applying swaging pressure while placing the new small swage clamp and boot into their final position on the halfshaft bar. Swage the clamp using J 41048 swage clamp tool (J 41048) by aligning both swage clamp halves onto the boot neck in the halfshaft bar's groove. Manually tighten bolts until they become snug but confirm there are no dangerous indentations on the boot. When using a ratchet wrench to tighten the bolts do 180-degree turns until every side bottoms out then relax tension between the dies for separation. Deformities in the swage clamp require the tool (J 41048) for re-swaging the clamp. Before installing the convolute retainer verify the swage clamp's "lip" integrity by checking the assembly position as improper installation may damage the boot. Before installation place the convolute retainer over the boot while keeping four convolutions inside while making sure rings completely engage their seating positions. Place the spacer ring and spider assembly on the halfshaft bar before setting the other spacer ring into its groove on the bar's end while ensuring complete insertion. Apply pre-measured kit grease to fill the boot and housing before putting the large retaining clamp onto the boot. Set the housing along with its new trilobal tripot bushing above the spider assembly before boot installation onto the bushing. Complete the inboard stroke setup by tightening the large retaining clamp to the housing with drive axle seal clamp pliers (J 35566) and removing the convolute retainer from the boot .
