Do CAM SKILLS, do just the bearings then? I think if you order them from perfect run you have to buy the complete hub which costs £150 a piece before shipping import duty e.t.c.
You can tell when the bearings shot when, with the wheel of the ground, spin the wheel you hear/feel a grinding noise(not being the brake pads). My bearings got play in it. so with a tighten it might sort that out but i've been driving on it so might just re-new anyway for piece of mind.
