Tesla recently replaced the low power switchpack - when I got the car back the steering wheel pointed a bit to the left to go straight ahead. Not the first time. When they replaced the low power switchpack last year I got the car back with the steering wheel pointed left to go straight ahead. Booked to go back in to Tesla next week. Here is where things get interesting... I jacked the car up (one side at a time) to swap the rear wheels out and to check the front + rear brakes. Front wheels removed and put back. Jumped in the car - now the steering is straight! There is no play in the steering. Are there any components that could resettle when the weight is taken off the suspension and lock down when weight is reapplied?
