I've started to notice a whiring or whining noise, sort of like a gear or bearing noise, maybe tire noise, at low speeds (30 mph and below). (If it were tire noise I think I'd have noticed it a long time ago.)It is speed dependent and seems to be more noticable on decel, although I may just not be able to hear it over he engine on acceleration. It is not noticable at higher speeds, like 40+. I tried coasting with the transfer case in neutral and the trans in park and the engine off, which should stop just about everything except the axles. No change. No change when turning, either (wheel bearings). If I had to guess, I'd guess it's coming from the rear and it is present on accel also.
I've heard similar noises in a lot of other higher mileage trucks, but they weren't mine so I never sweated it. My mileage is about 135,000
Should I sweat it?
(Update. I'm almost certain it's present under acceleration also. Seems to be unaffected by load, too. Only thing I haven't tried is going 20 mph backwards...)
