Right failed MOT today only a new number plate bulb needed and 2 rear wheel bearings. The tester said that bearings seemed fine and there was no noise just exsessive play. So suggested i just tighten then up a bit. Can this be done. Im getting new bulbs in the week for a re test on thursday. Can the rear wheel bearings just be tightened up then as i will do that 1 night this week.
