Hi, welcome to Just answer! My name is XXXXX XXXXX i will help with your question
Are you looking to replace the inner or outer joint?
yes , the shaft is off the vehiclr
Ok, there are different types of cv joint attachment, if you look where the splined section of the shaft enters into the back of the CV joint, there is usually a circlip, you need to spread the circlip open then knock the CV joint off, if there is no circlip, its just a case of holding the shaft and giving the back of the CV joint a good hard knock with a soft mallet. Ideally you need to put the shaft in a vice, or find some way of holding the shaft securely while you knock the joint off. they can take a few hits sometimes, be sure not to hit the bearing cage in the back of the joint, try to hit the outer edge of the joint but don't be afraid to give it a hard smack.
If there is no circlip, and the joint doesn't move after a few hard smacks, you have the one part shaft, which has the CV Joint fixed to the shaft and cannot be removed, if you have this type and only need to replace the boot you need to cut the old boot off, then use a stretchy boot and cone, the cone fits over the shaft, you can stretch the CV Boot on over the cone and onto the shaft, then fill with grease and fit the clips.
do you mean at the gearbox end, because at the outer end the shaft splays out to 3 fingers, that you would never get the new boot over, bare in mind , I am an ex mechanic myself
Yes if it comes to replacing the boot with a stretchy boot you need to put it over which ever end it will fit, it should stretch over the entire CV Joint without any problems if a cone is used.
have tried with force to separate the gearbox end from the shaft and have now damaged the inner boot and it still wont come apart, will be easier to get a second hand shaft, hopefully with decent boots on it, thanks for your help
No problem, you are correct in saying its easier to get a new shaft, if you don't have a flexi boot kit, its easier to just get a reconditioned shaft, then send your old shaft back under the exchange program.
