drive tire wear/ shimmying/ rear stabilizer bars

Shimmy's are caused by out of round or out of balance tires typically at 55 mph. Drive tires create a shake you generally feel in the seat, steer tires create a shimmy in the steering wheel. Usually worn spring and torque rod bushings do not create a sustained shimmy. If they are that bad to contribute to a shimmy or shake they are easy to see by eye.

 

If you mean the transverse torque arms, the bars that are perpendicular to the frame, very little actually. Those bars are only to keep the axle properly spaced side to side. The actual alignment is made by axle orientation front to rear. The side to side spacing is called tandem lateral offset. Worn bushings will contribute to wear, but not that significant. The axles would have more movement during turning due to side forces, but would generally ride centered once travelling straight ahead. Do you have any pictures of this tire wear?

 

ur pictures should be ok for uploading, following their formatting rules. ur a new user, just keep working at...i'd like to view them

 

??? pictures, im getting the impression you lost interest in your subject matter by not uploading pictures.

 

Have you had the wheel bearings checked for play?
