Default Help wandering steering belt car.

Have a TRF 419 belt car, and it wants to wander under power and off power, kinda like a torque steer, have rebuilt all shocks, checked everything for binding, replaced the servo and horn, reset ride height, set shock shaft travel equal, tried different receiver, checked all screws.

Check the bearings. Had one starting to seize on me one time that exhibited the same behavior

Bearing shimming differences, and maybe an overtightened wheel nut...

I rebuilt all the bearings, and properly torqued the wheel nuts, everything is free and true.

I guess you have a tweak issue then or left/right weight balance issue if the car comes off good on a hudy setup station...

Sounds like you have a twisted chassis.

With all the different types of plastics for cars, you might want to make sure the plastic compounds for all your a-arms are the same. Not familiar with the 419, so this might not be the issue.

No I don't have a set up board, bought it used, had two other used chassis with it, maybe the guy was a big crasher, and tweaked them all, that could be why he was selling it so cheap.

You might need to tear it down and check for bent bulkheads, hinge pins etc if that's the case.

I already rebuilt 90 % of the car, haven't seen anything to the naked eye that's obvious to me.

He gave me 2 other chassis, maybe I should try one of them, what do I look for on a bare chassis just to lay perfectly flat on a glass table?

No the cars steering wanders on and off power in different directions, all my other cars work fine in the same conditions, yeah I thought it might have been the crown in the middle of the street too.
