Shimmy & Shake
Posted by Tim on June 9, 2006
I recently had new radial tires & rims (10R22.5) installed on my medium duty truck. The truck shakes @ 70 through 90 KMH only when loaded. The cab skakes up & down, but the steering wheel does’tseem to be affected as when you have out of balance tires on a smaller vehicle. Would this problem be caused by…out of balanced tires on the front or rear axle?
Without seeing or driving the truck, I would be inclined to think that your problem is not tire or wheel related if the shimmy and shake only happens with the truck is loaded. Since you are not feeling anything in the steering wheel, it is pretty obvious that the problem is somewhere in the rear of the vehicle. Loading the vehicle would change the angle of the driveline. I wonder if there is a problem there?
