Had all my wheel alignment done yesterday.
Got told one of my rear bearings has play (Was brand new 6 months ago, the mechanic who did it is going to call me back monday)
And my rear wheels have a 12mm Step up.

Now we looked at the rear beam and couldnt see anything bent or out of place, all the bushes are in good working order.

Could a dodgey bearing cause 12mm of step up?
The car has never been in an accident, although looks like it's been driven through a war zone

Anyone got any advice on what to check?
Wheel alignment was done about 8/9 months ago last and the rear beam was fine then.

Bailes.
