If it's bearings, which it probably is. Make sure the garage (if not, yourself) do the rear bearings up to the right torque settings on a Corsa B (There's guides on here), mine were over done (to the Corsa C settings) from a garage, I had the rear wheel lock up on me!
Not sure about how specific the Corsa C ones need doing up, but the B needs to be pretty spot on.
P.S. <<<<< might be worth putting what Corsa you drive in your Profile <<<<<
