car was just in having both of them torn
seems kind of odd to have them both go (last service at the indy was about 10k mi or so)
since I never get under the car to look at things (live in urban environment with nary enough room in the shared garage to park, only know conceptually)

do these things hang down below other points of the car?

Our new garage has a pretty steep curb cut, maybe they are scraping the ground/curb/street going in and out of the garage?

If you bottom the car going in and out (i wouldn't of course, but the ms may..)
Can the cv boot hit the ground?

Do they just wear and age over time?

Recently did a 2200mi road trip from SF to Whislter,BC and back
Mostly highway miles, with a few miles of dirt roads (fairly smooth)

Also wondering if the heat from the car could cause the damage

TIA

cv boots go over time.
a dry, hot environment makes them deteriorate faster.
usually, they go somewhere in the mileage range of 120k to 150k on the cars that ive had.

knowing your mileage on the car will help us determine if the failure is premature or not.

in answer to your other questions, the cv boots dont normally come anywhere close to hitting the ground.
they are high enough to miss most anything you could drive over

we moved recently and have a new garage and was wondering the poor curb/"rockcrawling-like" entry into the garage could have caused this
I its possible to scrape the car, but I havent so far that im aware

They just wear out. Our passenger side went at 54k then the drivers side at 56k.

The are simple rubber pieces. There can be cracks in them that won't show for a year or so becaus no one will look that closely. A bad CV boot won't be noticed untill you hear CVJoints clicking or grease starts coming out of the boot leaving a grease marks on the underbody. This is when they get replaced.

Age, heat, movement, is what tears CV boots. Nothing is hitting them.

I've had them go 10-15k after being replaced. Their lifespan is hit and miss. They will go, and they will probably go several times.

Mine both went at the same time at 53k. I thought it was early, but dry in Colorado and apparently not.

longevity options:

SPRAY on silicon spray all around the BOOTS or use the Audi type of brake fluid and rub on the boot.

Both will lube and seal the rubber from the outside elements.

is it a bad strategy to leave a torn CV boot until the CV joint fails and than just replace with a new raxles axle?

I believe that I can cheaper change the entire axle myself rather than paying the dealer $200+ for a new boot
