Anyone have any DIY suggestions on how to replace two torn CV boots? Parts purchase? Tips? Special tools?

Can I ask what is CV boot?

Would this help? http://www.youtube.com/watch?v=JZoa1hTM74U

CV is for "constant velocity" joint. There are two for each driveshaft, with rubber boots to contain the oil and keep the dirt out.

Astoria makes a boot called Flexx which can be stretched over the joint, using a special tool (either a very strong cone, or an air-powered spreader).

Thank you Matt.

I think I post some experience when I was replacing the boot few years ago, but it is probably in the forum archives. Just like the video shows -all it takes to separate joint from the axle is a good swing with right hammer. I did it without removing the axle from the car, and since I was saving the joint -I used brass punch what added some difficulty, but it worked.

Thanks Kajtek1. I will be saving the joint as well. Recommend any parts supplier?

When I did the joint, the dealers "didn't do the boots" (gladly offering you $1200 axle) and I had to get it from aftermarkets.
Have seen somebody posting here a supplier at later time.

Off topic but I'm going through this with my Toyota right now. An Indy found a leaking CV boot on it today and their fix is to replace a 1/2 axle. Remanufactured part is $99.50 with $150 labor.

Just to add, this is the 2nd go around for these. Both 1/2 axles had leaking boots at around 75,000 miles on the car. It now has 117,000+ and the 3rd is shot. What I don't know without further research is how many years it has been since the other failures. Not that I'll add to this OT, but it's something I'm curious about.
