Hello,

With the previous three new cars I've owned, all front-wheel drive, I
drove them well past 100K mi. with each of them. But with all of
them, I've had to replace the CV joints for the same reason: the boots
dry out and crack, the grease comes out, and the dirt gets in.

Now, with my relatively new car, I wish to be able to avoid or prevent
that from happening again, so I did some research on CV joint
maintenance, and everything I've read talked about what to do when the
boots crack. Nothing about how to prolong their life or prevent those
boots from cracking.

The cost of the parts really isn't a problem, but you guys probably
know, it's a very labour intensive and time consuming repaire.

What's rather preplexing to me is that I read often how some people
who've put on >150K mi. on their previous cars, some having owned
about 5 or 6 different cars in the past and even living in northeast,
and never had a CV joint problem due to the boots cracking or failing,
let alone the CV joints itself going bad.

So, my question is, does anyone have a time proven or a definitive way
to prevent the boots from failing? I read how some would liberally
apply silicone spray on the CV boots and other boots everytime they
changed the oil. Would that be a good way to prolong the life of or
prevent the boots from cracking prematurely?

Any other suggestions or insight into this would be greatly
aprpciated. Thanks for your time and courtesy.
