I have always had a slight whine from what l thought was the diff at very slow speeds.. more noticeable when from cold.. l changed the diff oil blah blah but no different.. l even wondered if it might be normal for a LSD? Anyway, since fitting 20mm spacers to the rear hubs yesterday l think the noise has got a lot quieter.. so now l'm wondering whether if it might be a noisy wheel bearing and not the diff as the leverage on the bearings will have changed? Anyone have any thoughts..
