My T370 single axle box truck pulls hard to the right even after wheel alignment, mechanics can't seem to solve problem. No dragging brake, wheel bearings, tie-rod ends, steering box and pump all good. Steering won't naturally center itself at any speed.
You have to hold the steering wheel slightly to the left to stay straight. When you let go of it, the steering wheel goes to center then truck pulls hard to the right.
What could do that?
