What does the 'CV' in CV joints stand for?

Answer 1

constant velocity- the joints in the front drive axles of front wheel drive vehicles have a type of joint that allows the axle, or as it is called, half-shaft, to rotate at a constant and equal speed throughout it's range of motion.

It all depends on your skill level.I personally would consider it a 2 but i have been working on cars for about 11 yrs. I'll give you a quick runthrough of how to do it. Most people end up removing more parts than necessary. Star of course with lifting the car and securing it with a stand and remove the wheel. next you will need to remove the axle nut. this is the nut right in the center of the rotor. put some lube on before you remove the nut and the after try and spray some on the splines of the axle the tend to like to get stuck in there. next you need to remove the lower ball joint nut. some imports have bolts on the bottom of the control arm that secure the ball joint to the control arm if you car has this it makes it alot easier. if not remove the nut and put a prybar somewhere on the lower control arm. while putting a litttle pressure on the control arm take a hammer and hit the metal on the spindle around where the ball joint goes into the spindle. do not hit the treads of the ball joint. doing this will pop the ball joint loosse from the spindle. i wouldnot recommend useing a ball joint speperator or a pickle fork because these tools damage the balljoint dust boot and your ball joint will wear out faster. once the ball joint is loose pry it down and pullout on the spindle and the axle should fit out and be hanging free on the out joint. now you should be ready to pop the axle out of the tranny using the prybar. be cautious not to damage the seal . the axle should come out relatively easy. once out you can put in your new axle by sliding in the axle and lining up the threads be sure to get it in straight. you will not be able to just push it in. the esiest way to get it in is to find a metal pipe that will fit over the splines f the axle and tap it in with a hammer. DO NOT HIT THE AXLE DIRECTLY this will damage the threads and you will not have a good day:) once this is popped in just put it all back in in reverse order and you done. if you use this methos you will not have to remove brakes or struts or many other parts tha alot of people do. good luck.

Answer 3

CV - Constant Velocity

quoting from wikipedia - "Constant Velocity Joints (aka homokinetic or CV joints) allow a rotating shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play."
