I have a 2000 Dodge Ram 1500 2-wheel drive that I bought about 6 months ago. Seems like something is always going wrong with it. My current problem is that I have noticed a whining or whrrring sound coming from what I believe is the back underside area of the truck. It does not make the sound when it is in park and idling with the accelerator pressed, only when it is in motion. Furthermore, the sound pitch increases as the accelerator is pressed, then dies down when I start to brake. It sounds almost similar to an emergency vehicle siren. If anyone has any ideas, I would sure appreciate them. I do a lot of work on this truck myself and am better-than-average mechanically, but this one has me baffled. Thanks in advance!

a whine noise coming from the rear differential that changes with the throttle is gear whine. pinion bearings can make a noise that changes with throttle but is is closer to a growl. basically, the contact pattern on the gears is incorrect. it could be from wear, incorrect assembly, (backlash) or metal debris from failed bearings. it could also be low on fluid causing the wear, but once the noise starts, filling it back up will never stop the noise. the noise was probably there long before you bought it and is now loud enough that you noticed it. the differential will have to be dissasembled and inspected, most likely all bearings and the gears will have to be replaced. being a 9 year old truck, if it has limited slip, the clutches may need to be replaced now too. sorry

Sounds more like a diff problem. A wheel bearing is possible if the sound changes when your turning or cornering. Get the truck in the air and put it in gear and listen for the noise. If its towards the wheels it is a good bet you have a wheel bearing problem. More towards the center and it could be a axel bearing. See if you have any lateral or vertical play in the wheel. If not pull the wheels off and inspect the brakes to see if you have any diff oil getting past the axel seal. From there you should be able to pin point the source of the noise.

Sounds like the differential, pull the drain plug and check for metal in the grease. Could also be a dry u joint. crawl under and shake the drive-shaft, if there is any play in the u joints replace them right away

I agree with Sprinkle, it's your U-joint. Jordan has a point, but usually brakes (shoes that is) make a "shussh" sound, like a gentle rubbing.

rear end; aka differential. Might just need to be topped off with the proper lubricant. See your owners manual.

your brakes might not fully be disengaged. you can go to a local shop and have it checked out if you cant do it yourself and it shouldnt be expensive to have fixed. that sound like the problem

if the noise is on accel. it sounds like pinion bearings.
