I don't want to sound the profit of doom here Rob but.... the damage might have already been done simply by winding such a huge force on the relatively small taper rollers
Well as this thread has been here there and everywhere
Result from me
NOT wheel bearings
Just a bit of adjustment reqd to the taper rollers
Just to check I'd done it right I dropped in at CLARKES BMW ( bham)
all correct and done
At 22,500miles even they were suprised it had 'worn'
So I've completed the service, got a new front tyre to fit
All's well for this year now
Cheers all
