It may be low of lube or a bearing may be defective. Have it inspected by a professional.
wheel bearing, gearbox or wind noise Supercharger?
The noise is due to bad gears or bearings in your rear differential.
gears kicking, lots of whining noise??
Normally a whining noise in the back end means the differential is shot
From the rear it could be the differential, however those front differentials are notorious for making noise. That whining noise derives from the viscous coupler, and is normal. Bring it to a dealer, not some crappy backyard mechanic. And have a certified Toyota TECHNICIAN inspect the front an rear differential, transmission, and wheel bearings (but those typically hum when bad), I almost gurantee you just hear the viscous coupler noise.
I had a friend with the same noise his rear rotors were glazed over he got them cut and it went away. Don't know about the differential but the calipers may also be dragging witch is causing it to work harder
Can be a rear differential problem. May be Low of lube or gears are worn. Can also be a transmission problem.
sounds like the alternator belt is loose, check it out and let me know.
Gas Lid not tight is the reason my eng. Light keeps coming on
It may be the Idler pulley. I used to have a 96 Breeze with a 2.0L 4cyl that made a whining noise. I thought something might be seriously wrong, but then i discovered it was just the Idler pulley making noise. I changed it-- no more noise.
Hard to tell without hearing it. With engine running, open the hood and try to determine the area where the noise is coming from then repost info.
Whining noise near belts had pulleys adjusted any idea what is causing this
