I have had a steering wheel shimmy since the fall (40,000km's on truck). Previously it seemed to come and go once the suspension was unloaded (on a hoist lift). Now it is there all the time. Thought it was my 20" tires, so the 17" factories were put back on, same problem. Dealer balanced them and replaced one due to excessive road force. Still a problem. Dealer replaced intermediate steering shaft, hubs, axles, still shakes between 80-120km/hr. Truck was in the dealer for two weeks and they called me Friday to pick it up as they can't do anything further. They are now putting it in the hands of GM engineering to come back with a resolution. Anyone have any other ideas or had a similar issue?
