i was doing some work on my sportsman and noticed some wobble with the rear tires. I took the rear apart as far as i could go . I noticed there is a bearing and i have no ideal how to change the bearing. is there special tools and does the cv joint have to come out to ????

 

What makes you think that the bearing is bad? Usually a wobble (as the wheel is turning), without the noise of a bad bearing, indicates that something is bent. Just a thought...

 

I think wobble was the wrong word to use. when i had it on a lift is when i noticed the play (aka wobble) with the rear. its like the lug nuts are loose but they are not.

 

I replaced mine at about 3000 miles i had about a 1/2 inch of play in out at the top of the wheel. but even new bearings have a little play in them it definatly made the bike feel tighter on the road after i replaced them. as far as replacement the are like front brngs on a front drive car u must remove snap ring and press them out and then press them back in mine was extremely tight going back in. if ur not conf in replacing at least take the hubs off the bike and take them to a shop to just have brngs pressed that will save you some labor money
