What causes the CV joint boot to tear?

I have to change the whole drive shaft of the fron passenger site because of the boot. What is the cause? How can it be prevented?What causes the CV joint boot to tear?
The CV joint will inevitably tear. It's made out of rubber. When rubber gets wet - then dries, it will begin to degrade. Plus turning left/right (even though the boot is formed into an %26quot;accordian%26quot;) will slowly work at breaking down the rubber boot. Eventually - like all things made from rubber, it will become brittle and crack.

It's unfortunate that when they go you typically need to replace the whole front axel-shaft. But - it happens. I've heard that if your replace CV joints before they crack - they can replace the boot on-axel. However I've never had it done myself.

I guess CV joint damage prevention would consist of: Not driving on wet/salty roads, putting a rubber-stabilizer on the outside of the boot (although I think they already do this), re-apply said stabilizer regularly, make the boot of a more durable material, only drive in straight lines, drive in warm weather (where rubber is most maliable).What causes the CV joint boot to tear?
possibly hit something in the road or someone has damaged it while working under the car. BUT BESIDES THAT THEY DO GET OLDWhat causes the CV joint boot to tear?
heat dirt old age rubbing something

dont have to replace whole axle but just not knowing how long its been bad and how much dirt as got on joints is a good thing to do

but can just buy a cover boot and replace that sometimes all need to do is remove the tire

not a hard job to do at home with most cars just a few nuts or bolts axle pop out with a few good tugs cant really stop it just have to keep a eye on repairs they all go badWhat causes the CV joint boot to tear?
just wear and it dries out. you might try what i do. i spray silicone spray on my boots. it repels water and keeps them soft so they don,t dry out. i did that for years.
