My moto 4 did that. When the wheels are off the ground you can move the wheel side to side and the bushings were shot in the a-arms. When you spin the wheel does it spin easily or does it spin roughly? Your bearings might need replaced if the wheel spins rough.

 

i have checked the a-arms and they do not move side to side. And the wheels spin fine. So should i get new wheel bearings?

 

Did you tighten the hub? If that is not the problem i dont have a clue.

 

could be the alignment. my bars used to shake at high speed. turns out it was toed-in more than an inch! I took delivery of it new that way. a tape measure and a few wrenches and you are set.

point the wheels straight ahead and measure from one point on the front of the tire to the same point on the other tire.
then measure again at the back of the tire, and compare the numbers. it should be neutral or maybe toe-in [front of tires closer than back of tires] by a very small amount, mybe 1/8 inch.

it only takes a minute to check and if thats ok then you know youll need to look at bearings and hubs. try and do the simple stuff first.. [img]i/expressions/face-icon-small-wink.gif[/img]

 

Is it only at high speed?

Are you running slime in your tyres?

 

when i have the front end lifted up i can move the tires side to side a tad bit. No i am not running slime or any thing in my tires. Could it be the bearings are going bad?

 

its your hub dood

 

Side to side is hub nut is loose. Tighten it. If it was the bearing it would have a woble and or grind to it.

 

i tightedn it till i couldent turn it no more and it still moves right to left a little is the hub nut the one that is in the middle of the rim? cuz thats the one i tightend

 

yup thats it alright. what year is it? if its an early model or even a 2000 it could be ur bearings or bushings
