when i put in the bearings on my car the left rear axle went out crooked so i just stuck 1 bearing and a bushing, also the uneven suspension but i sanded down one side so they would be even. i also tryed centering my servo and checking if anything was wrong with the differential and checked the whole drivetrain. never tried the electronics tho. but if its just from the stoopid wheel on the controller thats a total mind blower
anyways ill check my controller
