I found a good cv joint with boot on ebay for only $100.00, I dont know where you got the $300 figure from....so if I need the whole cv joint replaced I guess Im only going to end up paying $100.00 plus labor if I cant figure it out.......thats all I need right?

 

wouldnt that make him pull to the left if the right spins faster than the left?

my guess is the opposite, the left randomly engages and goes faster and since the left wheel is spinning faster it would go right

 

The $300.00 figure probably came from the fact that to buy a new cv joint from the dealer it's around $270.00 just for the part. CV joint When I replaced mine I had the polaris manual with me and that really helped. Just do a search for cv and there's all kinds of info already posted on this.

 

yes wally is correct, its 270 from a dealer. some may charge more so u may see 300$, was a quick est.

 

my daughters starting doing the jerking motion to the right today during a poker run. I put it in 4x4 and took it out but didn't seem to make a difference..any suggestions?

 

a broken retention spring in the hub can cause unwanted engagement. may also be part of the problem.

 

First remove the plug from the hub and check the magnet on it for filings, hopefully it is clean or just has very fine wear stuck to it that you can't feel between your fingers.

Or even a stretched retention spring. Check the oil in both hubs and change it if its at all dark. If that don't cure it pull the rf hub apart and check the Hilliard rollers, roller retention spring and the cam inside the rollers. Look for rust, flat spots pitting or other nasty looking problems. Everything has to be in good shape shape.

Also don't stretch the spring to get the rollers out slid the cam out of the inside then carefully remove the rollers

Finally it could be a magnetized armature plate, @ $9 from leaving the AWD on a lot over several years.
All this is assuming that there is no issue with the cv joints on the rh side.
Here is a link to a manual on the older machines.
