  Q: How to replace the inner CV Joint and seal on GMC Savana 2500?

  A:

  You need a wheel drive shaft and two clamps: large clamp " and small clamp " before replacement. Use a side cutter or any suitable tool to cut off those pieces. Start by removing the tripot housing from the wheel drive shaft then push the tripot seal toward the outboard end. The tripot seal requires the tool J 8059 Snap Ring Pliers (J 8059) to remove its spider snap ring after which the entire assembly of spider, tripot bushing, tripot seal and spider snap ring needs disposal. Scrape the rust off the wheel drive shaft bar using a wire brush across the areas that will support the seal. To install the system place new clamps (4, 7) on the tripot seal before installing the seal over the wheel drive shaft. Finish by fitting the tripot bushing into the installed seal. Secure the new spider snap ring on the shaft through the J 8059 Snap Ring Pliers (J 8059) application. After you put the tripot housing over the spider assembly, check its bushing seat before inserting the tripot seal's small end into the wheel drive shaft's groove. Use J 43218 Clamp Pliers - Narrow Jaw (J 43218) to squeeze the small clamp until dimension (A) reaches 0.5-1.6 mm (0.02-0.06 in), then apply service kit grease into the joint and seal cavity. Prior to reinstalling the wheel drive shaft seat the large end of the tripot seal into the groove on the tripot bushing and check the joint stroke position to set dimension (A) to 176 mm (6.92 in) while venting the joint to remove trapped air before securing the clamp with J 46588 Axle Seal Crimp Tool (J 46588).

  Q: How to service and repair the CV Boot and CV Joint on GMC Savana 2500?

  A:

  Begin constant velocity joint boot maintenance and repair by removing the wheel drive shaft through correct procedures. Set the wheel drive shaft on top of a bench vise then cover its Axle Shaft with a shop towel. Use side cutters to remove the large seal clamp and small seal clamp then throw away these clamps. Move the seal behind the joint face by separating it from the joint outer race at the large end. Use an assistant to maintain the joint housing while an operator removes the outer joint from the wheel drive shaft bar after cleaning grease from the joint inner race cage and balls. First place a wood block between the seal and joint face at the joint area before hitting the block with a hammer to compress the Axle Shaft retaining ring until the outer joint detaches. The maintenance process requires wheel drive shaft bar operators to first remove both the retaining ring and seal. Begin installation by placing the large clamp and the small clamp on the seal before placing the seal onto the wheel drive shaft bar and adding the retaining ring. After using service kit grease to fill the outer joint you should position it at a horizontal angle while connecting inner race splines to Axle Shaft splines. Compress the Axle Shaft retaining ring using a flat-bladed screwdriver or equivalent tool to push the ring groove into the wheel drive shaft's open end while you fully press the outer joint onto the Axle Shaft. Work your way around the retaining ring until it becomes fully compressed. Use a wood block to protect the outer joint threaded shaft end while you hammer it until complete onto the wheel drive shaft bar. The mating groove in the wheel drive shaft bar must receive the small end of the seal before aligning the stepped surfaces of the Axle Shaft with its inner race. Begin by applying clamp pliers (J 43218) to compress the small clamp. Maintain compression until dimension (A) reaches 0.5-1.6 mm (0.02-0.06 in). After venting the joint, finish by securing the large clamp using clamp pliers (J 43218) until dimension (A) stands at 0.5-1.6 mm (0.02-0.06 in). Programming of the wheel drive shaft must be the final stage of the installation process.
