Right I had wheel wobble and a humming sound coming from the o/s/f wheel. So I changed discs and pads from tps (the old ones was rotten) I checked the wheel bearing for any play and there's non, there's no stickiness in the calliper either. No dodgy wear on tyres either. I did get it tracked for piece of mind and still no joy. So I'm stumped and no it isn't gearbox or drive shafts either. If anyone could shine sum light for me I would be grateful

try putting front wheels on back and back wheels on front ... will eliminate tyres / wheels.... are tyres on correct way? all directional arrows facing right way etc ...
