Hi RaceFan3
My TC3 have a same problem , I also change all new steering parts but no help. However, after I change all of the suspension arm mounts then my TC3 no problem and run very straight . And then I found the front F-2 arm mount left hand side hing pin hole can't hold tighten the inner hing pin . It will be changed the L/R wheelbase not balance and cause the car to veer.
