I need to know how to tell the diff. between a cv joint & a u joint. I asked the Polaris shop, & "all they can say is bring it in". Thanks for reading.

 

While I'm no expert on this subject I can tell you the a C/V joint has a boot over it and is usually located next to the wheel. A U-joint is exposed, also called a knuckle sometimes, and may have a grease zert attached to it. These are usually located closer to the middle of the atv. Some atv's have C/V joints all over and some have u-joints. The easiest way to tell is if there is a rubber boot covering up the joint. Hope this helps.

 

This is a copy and paste from the www.trustmymechanic.com

Constant Velocity (CV) joints are shafts that connect the transmission to the wheels with knuckle joints on either end of the shaft. The shafts provide the power to turn the wheels by linking the transmission to the wheel. CV boots are made of pliable rubber to cover the CV joint. Torn CV boots allow grease meant to lubricate the joint to escape, and allows dirt and debris to enter inside the joint. A worn CV joint usually produces a clicking noise from the wheel area on hard turns.

Drive Shaft and U-Joints -The drive shaft links the transmission to the rear differential to provide power to turn the wheels. Most drive shafts have two or three U-joints connecting the shaft to the transmission and rear differential. Some U-joints be greased

 

Thanks, I thought it had cv joints, now I know. Do you know where I can find them a a lower price than the Polaris shop wants?

 

Check this out. The part below the link is a copy of the email that I sent the guy. I meant to ask how much for the front axle which only has one cv joint.

Does the $169 include rebuilding the inner and outer cv joints (on rear of sportsman) with new cage, *****, race, boot, etc. or is that price per joint?

Yes the inner and outer on one axle.
