BMW 33213421367 Interior Repair Kit Bellows

When fixing a CV boot, always centre around a complete boot repair kit that involves the boot, clamps, special lubricants and another circlip. First you have to take out the drive axle. Remove the boot clamp on the front or the rear of the inner CV boot, then slid back the inner boot and unbolt the inner CV joint housing. Pop out the circlip which retains the triple roller bearing and thereby, expel the triple roller bearing. Slide the boot off the drive axle and split the inner boot adapter from the boot. Tape off and clean the old lubricant from the axle splines and also the splines of the triple roller bearing. To install the new inner CV joint boot follow the instructions given below:- Firstly, put the boot adapter into the boot then slide both the retaining clamps and boot over the drive axle, use the clamp pliers to ensure that the small end of the boot is sealed tightly against of the drive axle. Insert the triple roller bearing with the flat side of the joint towards the retaining circlip and then put back the inner CV joint circlip and fill the triple roller bearing and boot with new CV joint grease. Place the triple roller bearing into the inner CV joint housing and tight the boot connection with the supplied clamp of the boot kit. The rest of the procedure is the opposite of the removal, and at last, fill the differential oil.

When replacing a CV boot, use a complete boot repair kit available from an authorized BMW dealer parts department, which includes a new boot, clamping bands, special lubricant, and a new CV joint shaft circlip. Begin by removing the drive axle and placing it in a shop vice with aluminum jaws. Release the boot clamps from both ends of the outer CV boot, cut off the boot, and discard it. Use a soft-faced hammer to pound the outer CV joint off the drive axle, then pry the spring clip off the drive axle splines with a flat blade screwdriver. Clean the old lubricant off the axle splines and inspect the CV joint for galling, pitting, and other signs of wear or physical damage, noting that polished surfaces or visible ball tracks alone are not necessarily cause for replacement, while discoloration indicates a lack of lubrication. Place the new clamping bands and CV boot over the drive axle, replace the spring clip on the splined end, and pack the joint with fresh CV joint grease. Tap the CV joint onto the splined end of the drive axle until the spring clip snaps audibly into place, then use clamp pliers to secure the retaining clamp tightly, sealing the large end of the boot against the CV joint. Before installing the small boot clamp, flex the CV joint as far over as it will go and insert a small screwdriver between the boot and axle shaft to eliminate any air. With the outer boot full of grease and air removed, secure the small end of the boot on the CV joint by pinching the clamp with pliers. The remainder of the installation follows the reverse order of removal, and it is important to check the differential oil level afterward.
