Well had both bearings done today and I pleased to say that that horrendous noise has now finally gone!! So in the end it wasn't the tyres afterall!#
The only thing I noticed though when driving it home from the garage is there seems to be a slight bit of grinding noise coming from the brake area? As if the brake pads are catching the disc with each rotation. Is this normal after having bearings changed? I wondered if after the brakes have been messed with they might need bedding in again over time?
Thanks
