May seem like a silly question, but would it be better to change both sides a the same time? I can't work out which side the noise is coming from, it's just resonating around the whole cabin from the back end.
I fitted our spare tyre the other week after getting a puncture. I was astonished how noisey the car was. It was hummingreally loudlylike a wheelbearing. After getting the punctured tyre fixed i swapped it back and now the noise has gone. Its amazing how much noise crap tyres make.
