Hello Mr Joe.
You will get a kind of grinding sound when a CV joint is contaminated
with dirt, and a much louder noise, banging, clonking, and scraping if
the joint had broken apart in it's housing.
Looks to me like the Outer CV joint would cost you £68 GBP
(euro-car-parts), plus £13 for a new gaitor, and then £40 for me to
fit it for you!
The main cost involved (judging by the way you spell tire/tyre), would
be bringing the car to England so I can do it for you!
I recently had a gaitor split on my V70, and I was pleasantly
surprised at how easily all the suspension components came apart. The
driveshaft is held into the gearbox by a circlip, retaining it in
position when you remove all the other suspension parts, and therefore
you don't lose all the gearbox oil. This is unlike most other cars I
have worked on, and saves lots of work (draining and re-filling
gearbox, plus carefully removing/storing the driveshaft).
Anyway, I removed the assembly from the car, washed the CV joint to
remove any dust which may have ingressed, and re-assembled. I don't
know how long the Gaitor had been split for, because I only noticed it
when giving my alloys their 6 monthly remove/clean/polish.
Anyway, money can be saved by doing the job yourself, but I'd estimate
a dealer would charge at least 2 hours time, and the joint would cost
about £120 or more.
The main hub nut on the end of the driveshaft will be VERY tight, and
you'll need a substantial socket/handle to remove it. A 1/2 inch drive
socket bar would simply bend. I used a 3/4 inch drive bar, and had bo
problem. Just remove the nut with the roadwheel still on, and the
brakes firmly applied by an assistant.
Hope this helps.
