Fitting a new CV boot - The stretch type

My car failed its MOT for the first time ever. It was nothing serious, just a split CV boot (outer driveshaft gaiter).

Usually to replace such a cheap component means having to take apart the CV joint, and that is a tiresome thing to have to do. I had heard about split gaiters - where you wrap it around the CV joint and glue it. But I was unable to locate one. However, after searching the internet, I came across the stretchable CV boot idea and decided to give it a try.

The boot kit is made by a company called Bailcast and consists of the boot, a sachet of grease and the metal clips to secure the boot. The cone for fitting, seen on the right, was purchased separately but it is reusable. (My local Unipart/Partco had them all in stock)

After dismantling and the front suspension assy. and removing the strut. The old, torn gaiter was cut off and the CV joint cleaned up.

The new boot was turned inside-out and the outside of the fitting cone and the inside of the now inverted boot were liberally lubricated - There is a spray made for this, but standard silicon spray is what I used. It is just as effective and much cheaper.

Now came the clever bit. The thin end of the cone was inserted into the wide end of the boot. Then the cone was placed, wide end down, over the handle of a broom. The boot was then pulled, sharply, down over the cone. This was a lot easier than I expected. The boot stretched with very little resistance.

The cone was placed over the CV joint and the boot was pushed off the end of the cone...

...and onto the driveshaft.

The boot was turned back the correct way round and the thin end fastened to the driveshaft, using the metal fastener supplied. The joint was then packed with grease.

The other end of the boot was then fixed and the job was done.

In all I was very impressed with the ease of this system. The purist will say that the CV joint should be stripped and cleaned but if you do not have the tools, facilities, time or inclination to do that, then this is an ideal solution for a quick and relatively painless fix.
