Default Question About CV Boot / CV Joint

OK, this is about my GFs Mazda 626, hence why it is in this forum.

I recently took her car to the dealership and had it aligned. They called
to tell me it was done and all, but mentioned that a CV boot had split open
and was leaking grease. They didn't tell me which one nor did the paperwork they gave me when I picked up the car. So I have no clue which one is split.

Anyways, when I crawl under the car, what should I be looking for ?
And if a boot is split and leaking, how long until the CV joint will fail ?
This is one part of the car I know nothing about. Any help would be great !!
Thanks !!

You want to look up front at the two half-shafts that each connect the engine to a wheel. At each end, they will have a rubber boot covering the CV joint to keep all its good grease packing in and to keep dirt/junk out so it doesn't get in and trash the gearing. So, look for a rubber cover over the end of a half-shaft with a split in it and grease trailing out of the split.
If there is still grease inside that doesn't seem contaminated with dirt/junk, just replacing the boot and repacking the grease may be OK even for the medium/long term. If the split has been there for thousands of miles and the inside is pretty much empty/contaminated, you're better off replacing the half-shaft now. My guess is that replacing the half-shaft will be $300-500 including labor. Repacking/replacing only the boot will be more like $100-150 if you use an aftermarket boot that doesn't require the half-shaft to be removed in order to install the boot. However, you may have to go to a non-dealer mechanic to get something like that installed.
You and/or the mechanic will have to decide if the joint is too contaminated to take a chance on the boot-only repair.
The good news is that if the CV joint fails, you will know in advance by a clicking noise when turning, so you will be able to drive (not tow!) the car to have the half-shaft replaced.

Bad Ass info there man, I appreciate it !!

So what would happen if the CV Joint were to fail ?
Would that JUST result in a clicking while turning noise, or
could it be something disasterous at 50 mph ?? Again...thanks !!

You'll lose all forward propulsion and the piece dangling out of the transmission will beat the **** out of anything it can reach.

Get it replaced now or as soon as you start hearing a metallic ticking coming from it. You really don't want to wait for it to come apart.

I am gonna call and get it fixed tom. or Tues. day.
I looked and it's the passenger side front CV Boot.
It looks like it was slit with an x-acto knife or something, but
there is grease everywhere. I'm just gonna get a remanaufactured axel for
it so it will repace the CV boots on both sides. I looked around online and
saw that would be about 200 something for that, so it's not too bad.
Thanks for all the info man !!

if the cv joint is not clicking why not have just the boot replaced for about athrid of the price? the outside boot is the one that typicaly splits cause of all the twisting the front wheels have to do. should take a good mech. 1 t0 1 1/2 hours to do
