Richard:



It sounds like you have a shimmy problem rather than a wheel balance problem. This can be about 15 causes, and maybe more.



1. Maybe the number one cause of shimmies in Ts are loose tie rods.



2. Perhaps the number two causes is a worn pitman arm.



Other Causes



loose kings pins, loose front wheel bearings, bolts not tight on the bracket that holds the steering shaft to frame (that one took me almost two years to find one time), bent radius rod, loose radius rod, loose bolts in the firewall to steering tube, Loose gear case in steering tube, worn steering gear box and or gears and improper toe in.
