I recently took my Quest to get an oil change and the mechanic told me that I
had to change the fuel filter. But when I got home and checked the "check-
up" page he gave me of a mini inspection they did to the car --- the paper
said that my CV boot was leaking and that both axles would have to be changed.
(The mechanic didn't tell me that there was a problem with the CV boot, he
just mentioned the fuel filter.)

Anyway, what is the CV boot and how important is it to get the leak fixed? I
am going on a trip this weekend and I want to know if I am going to have any
problems with the car. If anyone can help me out, I would greatly appreciate
it.

Thanks a lot.

Which CV boot? Left or right, inner or outer? Be careful of a ripoff! A
split/leaking CV boot or boots does not automatically mean that the CV joint
is bad and that you need axle replacement. Read up on CV joints and boots
WBMA.

CV constant velocity.

The CV boots are rubber parts that cover the internals of the joints in
the drive axles, those which transfer power from the transmission to the
front wheels. There are two boots per axle (one on each end) and one
axle per wheel. If the boots are torn, they will allow the grease to
leak and the dirt to go in the cv joints. If unattended, a torn boot
will lead to cv joint damage. You can tell if they are good just by
looking at them and making sure that they are not torn, i.e. they are
not leaking grease.

Good luck

bmelend,

Think more along the lines of CV Bootie - For front wheel drive
vehicles, you must not only be able to turn the axels to spin the tires
and "Pull" the car, but you must also be able to steer. The CV Joint,
or Constant Velocity Joint allows you to do both - kind of like your
shoulder - rotator cuff. This joint must remain lubricated with a
special thick grease (You have heard of Axel Grease, of course) and the
bottie holds it in.

Start your car and turn your wheels hard to one side or the other and
shut it off, make sure it is in park and and/or has the emergency brake
(Manual Tran) applied and then look inside of your front wheels - Look
for a black rubber bootie that appears somewhat like a plunger head.
They should last for a long time, but things wear differently depending
on usage, humidity and a number of environmental and hazardous
elements.

Regardless, it should not be very expensive to change out now - the
expense comes if you ignore them and let all the fluid leak and the
joints inside locks up, or just as bad, break up.

Do a quick Google or Ask on CV Joints...plenty of info...

I have a 1999 Quest and at 105K my CV boots started to leak.
I had them replaced by my local mechanic. Price per boot was
about $115 (or so), plus labor.

Ahem... some people say you get torn CV boots by taking your vehicle to
get the oil changed...

LoL, I am one of those...

I was asking for some tire replacement underwarranty. 100% the boot was
good, I had replaced it less than 2 weeks before. After they had the
car on the lift, they agreed to the tire replacement but informed me
that I had a boot torn, no grease found anywhere but inside the boot.
When I saw which one was torn, they got another claim in their hands.

Thanks for everyone's replies! It sure did help. I decided to get them
looked at and make sure I take care of the problem before it is too late.

Hmmm. If they can't get money out of one pocket, they'll try your other
pocket.

You said "another claim." You took 'em to court? If I understood
correctly, well, good for you!

I swear, the things they'll do... My previous car, I bought 4 tires
during a "Free Lifetime Rotate & Balance" special. The second time in
there, "Steve" showed me condensation inside the wheel cylinder boots --
drops of actual *water*! Oooh! When I declined a brake rebuild Steve
cross-threaded one of the lugs -- only one -- with the impact wrench
badly enough to stretch it. I kept it as a souvenir.

My GF took her VW Passat to the dealer. They told her she needed new
tie rod ends. Tie rods are fine, there's one torn tie rod boot.
