Note: Before the necessary replacement of CV joint boots, analyze the various restoration options. It is recommended to replace the drive shaft with a reconditioned axle shaft, which can be purchased through the exchange fund of the company's service network - this will significantly reduce the waste of time and, possibly, help save money. Regardless of the chosen recovery path. before disassembling, find out about the cost and availability of spare parts.
1. Remove the drive shaft (see subsection 12).
2. Clamp the drive shaft in a vice with fabric pads, the presence of which prevents damage to the axle shaft. Check the CV joint movement in the radial direction. The presence of excessive movement indicates wear of the hinge parts. Make sure the hinges move smoothly in all possible directions. If the boot is torn, disassemble the joint and inspect its components - they may be excessively worn due to lack of lubrication or penetration of foreign particles into the CV joint.
Note: Some models are equipped with a protective cover that is fixed to each cover on the side with the larger diameter.
Using diagonal cutters, cut the ties, then pull the casing off the boot.
Inner CV joint
3. When replacing the inner CV joint boot, follow the accompanying illustrations (see illustrations 13.3a-13.3t).
13.3a. Using diagonal nippers, cut the boot clamps (the small diameter clamp has a clamp lock: this clamp can be cut using a hand-held power tool with a grinding disc; during assembly, a standard clamp should be installed, since a special device must be used to install a clamp with a clamp lock)
13.3b. Pull the housing off the tripod
13.3s. Pull the boot towards the center of the drive shaft
13.3d. Spread the ends of the retaining ring and pull it towards the center of the drive shaft
13.3e. Pull the tripod to open the locking ring; pry up and remove the ring
13.3f. Carefully knock the tripod off the drive shaft using a copper punch (do not hit it hard to prevent the tripod from flying off, as this may cause the needle bearings to crumble
13.3g. When tightening the drive shaft tripod, it is necessary to hold the bearing with your hand in its original position; it is preferable to tape the bearing to the tripod with adhesive or fabric tape
13.3h. Pull the boot off the drive shaft together with the retaining ring
13.3i Clean all old grease from the tripod and housing, then remove each bearing one at a time
13.3j. Carefully disassemble each tripod section, clean the needle bearings in solvent and inspect the rollers, tripod, bearings and pivot housing for material wear, signs of pitting and other defects
13.3k. Apply special grease to the inside of the bearings to glue the needle bearings, then slide the outer races onto them
13.3l. Wrap the splines of the drive shaft with adhesive tape to prevent damage to the boot, then slide the smaller clamp and boot onto the drive shaft
13.3m. Pull the tripod retaining ring onto the drive shaft, moving it past the mounting groove
13.3n. Install the tripod bearings by rotating the grooves in the countersunk hole towards the end of the shaft
13.3. Install the retaining ring, then pull it towards the tripod and seat the ring in the groove
13.3p. Fill the hinge housing with half of the grease supplied with the repair kit, and place the rest in the boot
13.3q. Placing the clamp in its original location (without tightening it), install the tripod housing
13.3r. Place the boot into the housing and into the groove of the drive shaft oil seal, then adjust the length of the joint according to the specification data in this chapter
13.3s After adjusting the length of the hinge, insert a small screwdriver between the cover and the body to remove excess air (make sure that the cover is not deformed)...
13.3t... then secure the clamp using a special tool (which is freely available)
Outer CV joint
4. When replacing the outer CV joint boot, follow the accompanying illustrations (see illustrations 13.4a-13.4r).
13.4a. Using diagonal nippers, cut the cover clamps (the small diameter clamp has a clamp lock; this clamp can be cut using a hand-held power tool with a grinding disc; during assembly, a standard clamp should be installed, since a special device must be used to install a clamp with a clamp lock)
13.4b Spread the ends of the inner snap ring, then pull the CV joint off the drive shaft
13.4s. Press the inner race in sufficiently to remove, turn the race with your fingers, gently tap it and the separator using a hammer and brass punch
13.4d. Pry the balls out of the separator one by one
13.4e. Rotate the inner race and separator 90°, then align the separator windows (A) with the grooves in the housing (B) and, turning the inner race and separator upwards, remove the elements from the housing
13.4f. Align the grooves of the inner race with the windows of the separator, then turn the inner race and remove it from the separator
13.4g. After cleaning the elements in solvent, inspect the grooves and depressions of the inner race for signs of pitting and material wear
13.4h Inspect the separator for cracks, signs of pitting and material wear; the presence of polished spots on the working surfaces is not a defect
13.4i Rotate the inner race and separator 90°, then place the elements into the housing
13.4j. Turn the elements by gently striking them with a hammer and brass punch...
13.4k...then press all the balls into the separator windows one by one
13.4l. Using needle-nose pliers, place a new retaining ring into the groove...
13.4m...then shrink the ring using special pliers
13.4n. Put grease into the spline hole of the hinge, then insert the wooden cylinder into it (the diameter of which is slightly smaller than the diameter of the drive shaft) and push the grease into the joint; perform the operation until the joint is filled with grease
13.4o. Install the smaller clamp and boot onto the drive shaft, then pack the boot with grease...
13.4p....so that its level reaches the end of the drive shaft
13.4q. Place the CV joint on the drive shaft, aligning the splines, then using a soft-faced hammer, tap the joint onto the shaft until the retaining ring fits into the groove
13.4r. Place the inner end of the cover into the groove and install the clamp, then do the same on the other end of the cover; tighten the clamps using a special tool (see illustration 13.3t)
