Question about 1992 GMC Sierra
Howling sound in right, rear wheel area. Lifted wheel and spun. Growling noise from within. Checked diff. for oil and was up to specs. Suspect wheel bearing if there is one at the wheel on the axle. Just don't know why it would go out with it being under costant lube. Truck does have 126K miles though! If it is bearing, is it too diff to replace? Have done many things in my life including rebuilds, but not anything to this baby yet.
It sounds like you know what you are talking about so you probably already had a look inside the brake drum for worn shoes and broken springs ect.........If you haven't do so.As for the bearing.....there is one but it requires dis assembly of the reared.if you haven't done one of these,get someone who knows how to..there are too many little things to know and its easy to damage the diff from improper dis and re assembly(then you're lookin at big bucks) If you feel confident you can do this though get a step by step manual to ensure you know all of the procedures
hope this helps.........Good Luck!
