I finished fixing my rear wheel wobble by replacing the rear bearings, and now I have had a little time to play. The front right wheel starts to hop or shake really badly at about 30 mph. I wouldn't think that this would be wheel balancing at these speeds. The tires and wheels I have on there are brand new. I'm just not sure what would cause it.

There is some play in the steering linkage. I have the joints to replace it, but that's tomorrow's job. I wouldn't think this would have much affect on the wobble though.

Thanks!

 

what is the toe in/out set at right now? that could also be a factor

 

I have no idea. I guess that's another question I need to ask...

okay here goes:

How do I set the toe? Not how, because that seems obvious, but how do I want it set, or how do I know where it is set.

 

I am not 100% sure what it should be at...I am sure if you do a search you will be able to find something to tell you how it should be set...and also the tires might be causing it too...are they the same tires you had on before? or a different brand/type

 

The tires and wheels are brand new, so I don't think that's the problem. I assume that they don't balance ATV tires. They are 26" BigHorns on Aluminum ITPs.

 

Big horns are more agressive right?? if that is the case then it could be the tires themselves...if you upgrade to the more agressive tires you will get more bite to the sides...causing it to jerk

 

What kind of machine are you working on here? How old is it?

 

The machine is a 96 Sportsman 500.

I don't feel like it could be the tread as it only seems to do it on one side. I guess I should swap the tire to the other side and try again.

 

Here are a few of ideas. Worn out springs. Worn out struts. Bad bearings. One hub staying engaged. On a unit that old it could be any or all of these things. (As well as others.)

 

hey thumper, didn't you just have the rear axle apart? check the alignment of the u-joints. if they are out of line this will cause exactly what you are describing, it'll be the rear but feels like the front. the joints must line up exactly or the timing of the axles are off and the joints wont bend correctly.
