Answer 1

what and where is the CV joint?

Lets first talk about a "U" joint. A U joint is basically a cross or "X" shaped center piece held in two "U" shaped arms. (I'm not explaining this well, but you see U joints every where. Anywhere you've got turning shafts like steering linkages and drive shafts you'll find U joints) U joints are cheap and strong but they have a draw back. As the operation angle gets greater they actually speed up and slow down as they rotate. Hence they are NOT a "constant velocity" joint. This would causes major handling issues for full time 4wd and fwd cars. (Imagine if you turned a corner and the wheels started speeding up and slowing down of their own accord. Talk about screwed up handling )

A constant velocity (CV) joint is used anywhere the smooth delivery of power is needed.

I don't know the specific details of your jeep but there are only 4 places that could have CV joints. They are the front and rear drive shafts and the front steering knuckles. If your jeep has them on the drive shaft they may or may-not be covered in rubber boots. If it has CV joints in the steering knuckles they will be in a rubber boot.

Answer 2

If you look under you Loredo you will see a bar that goes to the wheel and it has a big rubber cap on it..well that rubber cap is the CV joint .there is one at the wheel that is called the outter CVjoint and the one comming from the transmission is called the Inner CV joint..and if you have an all wheel drive then you will have one of these shafts at every wheel..A CV shaft is just a drive shaft with without a U-Joint ..it's made to turn at high speed at all angles..the reason for the big rubber boot covering the Joint is that it's full of grease and if this boot splits or cracks then the grease gets pushed out when you are driving ..so once the grease is all gone then your joint will be "dry" and you will start to notice a clunking sound when you turn...it's very easy to change these shafts your self..all you have to do is remove the tire and then remove the big nut that hold the shaft ..then drop the bottom ball joint and pull the hub away and then the CV shaft will drop out from the wheel assembly and then just pull it out of the tansmission..and then just do the steps backwards to put everything back together..just try and get a torque wrench to put that nut back on the new shaft because it should be torqued to atleast 175 to 180 ft lbs ..if you need any more help don't be shy to ask for it..

Answer 3

okay first dont listen to any one else about this topic the cvjoint not u joint is located in the front of your car if you want to replace them this is the process. unbolt the five lug nuts, remove tire. second geta 34 or 36 mm socket cant quite remeber. take the cotter pin out of the axle nut (the biggest nut) then use the 346mm socket and impact gun as these should be torqued to 175lbs of pressure (make sure you retorque them to that when reinstalling). alternate way is to have a friend hold the brakes and loosen the nut with a breaker bar. then use a 7/16 wrench or socket (again maybe different size) to unbolt the disc brake caliper, slide it off then the rotor. now there will be three bolts going through the hub assembly( the part that the tire mounts to and spins) the will start from the back and thread in the front you will be able to see the ends of them in the front.they will be 13mm thats for sure they are also the 12point bolt heads meaning you will need to use the round end of a wrench or a 12point socket. remove these then pull the hub off will probably be stuck so knock it off but dont hurt it. then pull the front axle out the black boot is protecting the cvjoint which does mean constant velocity joint. you can get a new one at advance auto parts for like 80 bucks. then reassemble and dont forget to torque the big nut to 175lbs. any other questions email me at [e-mail]

Answer 4

I don't know what a JGC Loredo is, but i'll assume you mean a Jeep Laredo. The CV, or constant velocity joints are under the car where the axles meet the hubs. They have a ribbed rubber boot to protect them.

Answer 5

Hi there ,
I am not familiar with the Quadratrac, however a CV joint is a constant velocity joint and is usually found attached to a drive shaft. It allows the drive shaft to move through differing angles while maintaining drive. It usually has a rubber boot around it which is filled with grease to keep it lubricated. So, to sum up, the CV is the bendy bit on the drive shaft!!

Hope this helps.

Answer 6

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. They are mainly used in front wheel drive and all wheel drive cars. However, rear wheel drive cars with independent rear suspensions typically use CV joints at the ends of the rear axle halfshafts. Audi Quattros use them for all four half-axles and on the front-to-rear driveshaft (propeller shaft) as well, for a total of ten CV joints.

Answer 7

these joints are just inboard of the front wheels/brakes. the joint allows the drive power to be sent to the front wheels as the wheel moves up and down and as it turns left and right. the rubber boots split open and spill the grease every once in a while,and as long as you get the boot fixed in a few days, no real damage is done to the joint. about 175 bucks a side. let it go too long and it gets real $$$$$$

Answer 8

CV (constant Velocity) joints are typically at at least one end of a axle connecting a drive hub to the differential. In your case (all-wheel drive) there could easily be four (4) or more.
