I just had some new rims put on today, and as I am unlocking the old rims I notice grease all over the front right wheel. This is the 4th or 5th time in less than 3 years that I have had a torn boot. I believe it has always been the outer boot and it has happened on both sides. My uncle who has been a vw mechanic for over 30 years now replaced not only the boot but the cv joints on both sides only recently, so I know there is no problem with them, but those damn boots just keep ripping and we can't figure out why. Does anybody have any ideas? Because I am fresh out of them.
