We talked the other day about wheel bearings. I thought you were asking about the front bearings. The rears, I believe are from a Merkur Scorpio. I have not heard pf anyone having problems with these. I have over 10,000 miles on mine and have had no problems at all. Hope this helps. The fronts are from the Ford Fiesta and many of the guys in England have complained of a weak spindle/bearing package on the front. GTD Racing and probably others have an upgraded, heavier duty front spindle/bearing package. The main complaint seems to be that flex in the smaller front spindle allows "knock back" of the front brake pads under hard cornering.
