Should warrant checkers have a list of the type of wheel bearings in vehicles?
I have a Fiat Uno and the rear wheel bearings are sealed ones. They are secured with a 160 lb ft torque nut which is staked. Does that affect how much play is safe when there is no noise for the bearing?
I read sealed bearings should have no play, but adjustable ones can have some. Therefore should the warrant checkers know which are which?
I have been struggling to measure the play which seems to be about
0.25mm or 0.3 mm at the rim. I mean to measure it better, but at the moment I feel that the wheel with the lesser play was rejected, the other said to be marginal. But maybe both are unsafe for sealed bearings? They do not have noise or roughness but without the brake drum on they do not continue to spin.
