Don't know if this has anything to do with what you call a wobble, however on out 2000 coach with the f53 chassis, there was a problem with the Accuride wheels/rims that came with the coach.
The center pilot hole in the wheels are slightly larger than the front hub pilot guide resulting in the wheel not being perfectly centered on the hub,
Neither the lug nuts nor the stud holes in the wheels are beveled which adds to the problem of not being able to center the wheel on the hub.
At one time some company sold shims that slipped over the stud bolts for centering the wheel, but were very expensive.
If that is your problem, you would feel of a vibration more like an out-of-balance wheel, but not a wobble, anyway that was my experience. Your problem may be completely different.
I was able to get the front wheels on our coach fairly well centered by using a feeler gauge, much effort and a lot of patience.
The wheels fit OK on the rear drive hubs, it' just on the front where the problem exists.
Wishing you the best of luck getting your issue resolved..
