i have a 2000 polaris scrambler 500 4x4 that is completely stock. maybe someone can help me figure this out. last week i was sliding around in 2wd in the snow and the 4x4 right hub locked in. i didnt know what to do so i just put in 4x4 and left it there. the next day i was riding it in 2wd again the same hug locked in when i was at a very high rear wheel spin and is shattered a u-joint and bent the yoke. i got the new parts and i dont want to put it together until i find out whats wrong. can somebody please help me with this problem.

 

I have a 2001 scrambler 500, I last month i had the same problem then you. You have to change the spring and the plate with 3 pins in your right hub. After that everything will be fine.

 

Is that it because i have been told that it could be low fluid too. Because when i took it apart there was no fluid in it. That was just the way i got it. When i took it apart all the springs and pins were in perfect shape.

 

If you had NO fluid in it, then that right there could have caused the hub to engage

 

yeah that was your problem im almost 100% positive after hearing that u had no fluid in it... make sure you have the right ammount of fluid in it i think they take 4 Oz not that much and its real cheap also... sence this problem youve had i would check the fluid at least once a week

 

Does anybody know if the u-joint that is open and the u-joint that is in the boot on the axle are the same size or is different, beause i ordered my parts and got them and the u-joint is to big for the yoke coming of the differential. And does anybody know were somebody sells really cheap u-joints. If somebody knows please tell me becuase i cant wait any longer to ride this beast![img]i/expressions/face-icon-small-smile.gif[/img]

 

i dont think there is a u joint in the boot i think thats a CV joint

 

it is thank you for all your help.

 

Polaris uses industry standard parts for their bearing and u-joints. If you take the old one down to an auto parts store, they should be able to match it up.
