Outer CV Joint Boot, Front

To service and repair the constant velocity joint boot, the following tools are essential for the exercise: j 8059 snap ring pliers (Parallel Jaw), j 35910 drive axle seal clamp pliers, and j 41048 drive axle swage ring clamp. To begin with, de-clip the swage ring from the halfshaft bar using a hand grinder without damaging the halfshaft bar. Finally, remove the big seal holding clamp from the tripot joint and side cutters and toss it out. Disengage the inboard seal from the trilobal tripot bushing of the large diameter and move the seal away from the joint on the halfshaft bar. Take off the tripot joint spider and the halfshaft bar housings. Spread the spacer ring using j 8059 and remove the spacer ring, spider, and tripot boot and discard the boot and rings. Use a wire brush to clean the halfshaft bar from rust in the boot mounting area and check out the needle rollers, needle bearings, and trunnion and replace damaged parts with the necessary kit. When installing use a vise for attachment to eared clamp: put the new small swage ring or eared clamp on the small end of the joint seal and slide it onto the halfshaft bar. Using the small end of the joint seal push it into the joint seal groove on the halfshaft bar. For swage ring installation, mount the j 41048 onto a vise, position the inboard end of the halfshaft assembly into the tool, align the top of the seal neck on the bottom die, and position the top half of j 41048 onto the lower half. Check for pinch points on the halfshaft inboard seal, insert the bolts and tighten by hand only. After that, install the halfshaft inboard seal, the halfshaft bar, and swage ring and tightening each bolt j 41048 180 degrees at a time using a ratchet wrench alternately between each bolt until both sides are bottomed. Crimp the eared clamp using j 35910 torque wrench, and a breaker bar. If available, fit the spacer ring into the groove of halfshaft bar with j 8059 and slide the tripot joint spider assembly along the halfshaft bar as far as possible. Add roughly half of the grease from the service kit into the great from the service kit into the halfshaft inboard seal while retaining the rest of it to pack the housing, leaving that trilobal tripot bushing straight on the side of the housing. Mount the trilobal tripot bushing to the housing, apply the larger new seal retaining clamp to the halfshaft inboard seal, and slide the housing over the tripot joint spider assembly to the halfshaft bar. Slide the large diameter of the halfshaft inboard seal over the tripot bushing and align the lip of the seal in the groove. Mount the joint assembly at the correct vehicle dimension of 106 mm (4.00 inch) while carefully inserting a smooth flat blunt tool between the large seal opening and the trilobal tripot bushing to even out the pressure and withdraw the tool as well as it. Reposition the halfshaft inboard seal, tripot housing, and grip the large seal retaining clamp while latching and experiencing a tool with skid ejector j35910 (if need be add the breaker bar and note wrench assist), crank down the seal retaining clamp with j 35910 to 176 n.m (130 lb ft). Make sure the gap dimension on the clamp ear and tighten until 2.6 mm (0.102 in) dimensional gap reached and fully stroke the joint varied number times to disperse the grease.

To replace the rear wheel drive shaft outer joint as well as the wheel drive shaft boot, remove the wheel sock drive shaft from the vehicle and install onto a soft jawed vice in such a way that the inboard or outboard boot technique does not get damaged, causing a reduction in the sealing surface and the wear off. If the wheel drive shaft has a low-profile boot clamp, remove and throw away the outer boot clamp and inner boot clamp from CV-joint boot then remove CV joint boot from the CV-joint house. For the shafts with the ear type boot clamp, remove the outer boot clamp and inner boot clamp before lifting off the CV joint boot from the CV joint housing . Using hammer and piece of wood to unscrew the CV joint from the wheel drive shaft and later use the J 8059 to remove the retaining ring from the wheel drive shaft and also take the CV joint boot from it. Specialize in inspecting the CV joint by laying the boot and clamp on the wheel drive shaft without crimping, with the boot being seated in the groove at the wheel drive shaft. Install the retaining ring on the wheel drive shaft using J8059 so as to not exceed 1.8mm (0.07 in) if the vehicles have X88, otherwise 2.6mm (0.10 in) if the vehicles have Z88/W49/WDA. Close J 35910 boot clamp until the gap is of the stipulated dimensions. Mount the CV joint on the wheel drive shaft using a block of wood and hammer and into the CV boot inject half the lubricant and the other half to the inside of CV Joint, removing excess lubricant. In case the wheel drive has an ear type clamp, close it using J 35910 until the gap measures 1.9mm (0.07 in) for the vehicles with X88 into ensuring the locking tabs get securely implemented. Lastly, close the boot clamp with CH 48894, then rotate the CV joint in a circular motion 4 to 5 times to spread the lubricants, pull the vise apart from the wheel drive shaft and replace the latter.

A technician needs three specific tools to repair the constant velocity joint boot: j 41048 drive axle swage ring clamp, j 8059 snap ring pliers and j 35910 drive axle seal clamp pliers. For constant velocity joint boot service and repair technicians need j 41048 drive axle swage ring clamp (J 41048) along with j 8059 snap ring pliers (J 8059) and j 35910 drive axle seal clamp pliers (J 35910). Cut the large retaining seal clamp from the cv joint with a side cutter before discarding it while maintaining care not to damage the wheel drive shaft inboard boot. A hand grinder will help you cut through the swage ring before you can detach the halfshaft outboard seal from the cv joint outer race. Move the seal off from the cv joint and clean away the grease from the cv joint's inner race facing. Use the j 8059 to expand the race retaining ring's ears before extracting the cv joint assembly off the halfshaft bar. Use a brass drift to lightly strike and swivel the cv joint cage so you can extract the chrome alloy balls before disposal. A thorough cleaning process with solvent removes contaminants from inner and outer race assemblies and.cv joint cage and chrome alloy balls. After drying all components, inspect for any signs of unusual wear, cracks, or damage which requires replacement of broken parts. Clean the halfshaft bar using a wire brush until all rust presence is eliminated from the seal mounting area. Begin by mounting the halfshaft into a vise before installing the new swage ring or eared clamp onto the outboard seal's neck and sliding the outboard seal onto the halfshaft bar. Installation of swage rings starts with placing the halfshaft's outboard end inside j 41048 before bolting the ring into proper alignment. Use the j 35910 to crimp the eared clamp to 136 n.m (100 lb ft) while performing gap dimension verification. Using grease lightly coat the ball grooves on both inner and outer races then fit the inner race into its cage and line it up to the outer race. Place chrome balls into position then drain grease into the cv joint space until reaching the retaining ring location at the bottom of the halfshaft bar. Apply the large seal retaining clamp to the outboard cv joint outer race using the j 35910 tool then tighten the clamp to 174 n.m (130 lb ft) while maintaining the specified gap requirement.

Place half of the lubricant in the CV joint boot and the other half in the CV joint.

Remove the small seal clamp from the wheel drive shaft bar using side cutters and discard it.

Remove the tripot spider from the wheel drive shaft.

Use J 8059 to remove the retaining ring from the wheel drive shaft.

Move the CV joint in a circular motion 4 to 5 times to distribute the lubricant, then remove the wheel drive shaft from the vise and reinstall it.

Use a flat-bladed tool to remove the boot retaining clamp.

Measure the distance from the rear of the boot to the front of the boot clamp (a).

Install the inner tripot retaining ring.

First, remove the wheel drive shaft from the vehicle and secure it in a soft jawed vise.

Mark the tripot spider position on the wheel drive shaft bar before disassembly.

Place half of the lubricant inside the CV boot and the other half in the CV joint, removing any excess lubricant.

The gap should measure 1.90 mm (0.070 in) using J 8059 (Snap Ring Pliers).

Rotate the housing in a circular motion.
