What is the latest on this issue? I have done all the usual, balance, rotation, shocks etc.
Is there a fix?

'94 4wd XLT

 

What speeds does it happen at? If they'll let you, watch when the spin balance the wheels. Might have bent rims or out of round tires or something. Sometimes the tire people don't pay much attention except to put weights where the computer says.

 

It happens at about 50 mph and above. I would think that if it was balance, it would change with rotation. But it always seems to come from the front passenger side. Last night driving home in the rain it seemed almost totally disappear. ????????????

 

I had the same prob- I replaced shocks and radius arm bushings. no more shimmy. drives great.

 

Radius arms, are they the ones that extend at an angle to the frame?

 

yes those are the ones, extendinding rearward from just below the shocks. there are many postings here on this topic. the bushings get old and crack and need to be replaced. job can be done yerself and can cost 800 + at a garage.
