ok this is doing my nut in ive had the ff tracking done twice in the past month and each time after about 2week the steering wheel starts to move from centre to the left how the hell is this possible i watched them lock the steering in the centre before adjusting so how ,,they said it was 4 degrees out and adjusted accordingly someone PLEASE explain how this is possible [i know its not fairies or my sons removing the steering wheel as im in sniper mode at night through my front window]

note to self..use a reputable garage ; computer tracked drives like a real one
