Predator 90 rear wheel wobble
I just purchased my son a 2006 predator 90, and noticed the rear wheels wobble. I can shake them side to side by hand with the machine on the ground. Im new to this bike so i dont know for sure but im assuming this isnt normal. ive googled it for hours and cant seem to find where anyone else has had this problem. Any help is greatly appreciated.
Thanks.

If it's not a hub problem or axle problem, then probably worn rear housing bearings and seals. You don't have to pay high prices for these bearings if you can get the universal off them and check your local auto supply/bearing house or even online. Same for the seals. Items#6,7.

Thanks. I was hoping you would see this post. from the reading i have done it seems you know these quads. I put the bike on stands and it seems the hub is loose to the axle. If i tighten the castle nut all the way down it is better, however it is way past where the cotter pin would keep the castle nut from backing off. Any ideas there? I would rather someone with experience tell me where to start than A: take it to a shop, B: start buying parts un-necessarily. I just bought this bike last night and have until 4/12 to make it right for my little ones birthday.

Another question if i may. I rode the bike around before i bought it (didnt notice the wheel wobble until i got home but oh well), runs great however up until about 1/8 to a 1/4 throttle it just revs up and doesnt move. After 1/4 ish throttle it catches and takes off. I wasnt expecting it and it chirped the tires. I have to admit i havent pulled the plug or taken the carb off to check it yet since little man is here this weekend but will tomorrow while he is in school. Anything else you can think of that i would need to check or is this normal? I know on the four strokes i have (had) that would not be normal. Two strokes= whole new ball game for me so i apologize if these are stupid questions.
Thanks for the help thus far.

On the hub you might try to add another washer and see if you can tighten the hub nut up enough and still be able to line up the cotter key. The hesitation could be carb related or worn belt or clutches. Easiest to check the carb first.Just take it off and blow out the carb jets and see if it helps. Again the manual can help you on a lot of maintenance/repairs.

Hub splines are softer than axle splines. That's why I mentioned trying to add another washer behind the hub nut to see if it helps snug the hub up better..If hub splines are really worn,then replacing them might be best.Not cheap,about 50 bucks each from here..Dirt Cheap Yamaha, Polaris, Suzuki & Kawasaki OEM Parts & Accessories – Cycle Parts Warehouse Plus you can check Partzilla,etc.

Thank you for letting me pick your brain, until inget to download the manual youre my only hope lol. With the bike on or off thengrpund the splines seem good (rotating wheel front to back on machine). The wherl wobbles side to side almost like the hub is too big for the axle. Should i try putting a washer inboard of the hub so that the cotter pin still lines up witg the axle key? And is the washer thats there supposed to be on the outboard side of the rim?
