Doug Thompson Posted March 24, 2009 Share Posted March 24, 2009 I have long been told that on the rear wheel bearing/driveshaft assembly if the dust shield thingy rotates freely then the assembly should not be used, is this true ??

mikeyb Posted March 24, 2009 Share Posted March 24, 2009 dunno about "should not be used" Doug, but I've always used that criteria to identify a bearing with too much endfloat! Depends how are your others are by comparison! Link to comment Share on other sites More sharing options...
MarkDeTriomphe Posted March 24, 2009 Share Posted March 24, 2009 Mr Witor claims that the shaft and more often than not the hub itself will not be salvageable when this has happened. I've never pulled one apart myself to see. I also met someone who supplies reconditioned hubs who didn't seem to concerned about the state of the hub provide for exchange. Personally, I have fitted shafts in this condition to keep me going in an emergency and not noticed any nasty noises or movement - but I tend to believe Chris and would not spend any money trying to recondition a shaft where the shield does rotate.

thescrapman Posted March 24, 2009 Share Posted March 24, 2009 I applied a variant in that theory..If the shield rotates, and teh 2 nuts are still locked together, bearing worn out.I had a rotating shield, and unlocked nuts, so tweaked the inner nut tight, locked the outer one in place, and did the RBRR.And 5k since.CheersColin Link to comment Share on other sites More sharing options...
Doug Thompson Posted March 25, 2009 Author Share Posted March 25, 2009 bearings seem okay ,turn nicely no funny noises ,no slack okay I won't throw them awayCheers Doug Link to comment Share on other sites More sharing options...
tonypy2 Posted March 26, 2009 Share Posted March 26, 2009 I've stripped and rebuilt several hubs, the spinning dust shield is usually a sign that the adjusting nut has been overtightened causing the inner race to turn on the stub axle, often this leads to a groove being worn, rendering the stub axle scrap. Often mechanics just tighten the adjusting nut to remove any excessive end float without carefully checking it with a dial gauge, this may get the car through the MOT but is asking for trouble in the long run.
