2436.0. "CV joints" by MUGGER::HUGHESS () Tue Aug 01 1995 13:30

Can anyone out there provide me with information surrounding The CV joint.

I have two cars one 5 years old and one 9 Years old, both I've been told 
have damaged CV joints, The 5 year old one makes a clicking noise when full 
lock is on turning to the left. The 9 year old car is making a disconcerting 
crunching sound whenever I have the wheel slightly turned to the left.
However, the noise on the 9 year old car can disappear for days on end. 

My questions.

What is the cost of replacing the CV joint, does it need replacing or can it 
be repaired?

I'm I endangering my life, pedestrians and other road users, driving with 
damaged CV joints. I know it is a test on the MOT to check CV boots.

What happens when the CV joint fails, will I lose steering.

	One more question How do you damage CV joints. Is it the way I drive or am I just unlucky to have two go at the same time?

	�What is the cost of replacing the CV joint, does it need replacing or can it �be repaired? The cost is (if you are prepared to do it yourself) somewhere between �70 and �150 pounds depending on the make of the vehicle. And no, you can't repair them. �I'm I endangering my life, pedestrians and other road users, driving with �damaged CV joints. I know it is a test on the MOT to check CV boots. Driving with a defective vehicle should always be viewed as endangering other road users etc,... �What happens when the CV joint fails, will I lose steering. When it fails completely, you will lose some degree of control, dependng on how it fails. CV joints usually fail because of a damaged boot which allows dirt and grit etc, into the joint causing excessive wear. Clive

	I'd disagree with .-1 in that the only control you loose is the ability to move forward. The CV joints are (you have 2 or even 4 ) in the driveshaft from the engine to the drive wheels. it allows the wheels to move up and down and turn whilst the engine stays where it is, whilst still transferring drive to the wheels. Hard driving, and racing takeoffs are contributory to it breaking down. A split boot could be caused by anything, but once it happens dirt can enter and start to cause wear in the joint unless it's caught quickly. It will NOT affect your steering, or your breaking ability. Just all of a sudden you'll be able to rev as much as you like in gear, with the clutch out and not go anywhere. Richard There are full Constant Velocity joints at the junction of the driveshaft with the wheels, often there are also similar flexible joints at the other end of the driveshaft where it enters the differential at the back of the engine (unless it's a Saab 95 in which case it's in front of the engine!).
