Why is the rear end making a whining noise

The whining noise could be for many reasons. Narrowing the possibilities depends on when the noise occurs. If it happens only while decelerating at any or all speeds is most likely caused by bad pinion bearings or loose pinion bearing preload. If it happens during acceleration over a small or large speed range is usually caused by worn ring and pinion gears.

One cheap thing to check is the fluid level in the differential. If low, topping off the lube may help for a while.

Noise in rear end

Provided that this is a rear-wheel drive vehicle, there are a number of things which can make noise when you accelerate. Most are due to excess clearance in moving parts. This means some parts are worn out.

On the outside, the U-joint next to the rear differential can be worn and make noise. Inside the differential, usually a pinion bearing(carrier bearing) can make a noise like a whine or growl depending on the gap.

Now in the axle tube, the axle shafts have a bearing on each wheel. Like any bearing, when they wear out, noise usually indicates failure.

When Torque is applied on acceleration, the parts shift creating noise. If you have a Limited Slip Differential, there are clutch plates which have a material which can wear out. These types of rear ends also need a special Additive to make the parts work. Sometimes you get a clatter when the additive is low.

Have the U-joint checked first as it is the only external part to check. The rest will need disassembly.

Please rate my info.

Two weeks ago I had my mechanic fix the leaking rear differential pinion seal. I am now noticing a loud whinning coming from the rear of the truck. When I take truck out of gear while rolling (above...

When a pinion seal leaks gear oil, dirt usually gets inside the gear case. The first bearing to get damaged is at the front of the pinion shaft. It's a standard practice to inspect it [ if any damage is noted, then investigate further ] when replacing the seal and change the gear lube as it's usually contaimiated. Another item is the tightness of the retaining nut on the front of the shaft which sets the pre-load on the pinion bearings, if this is set too tight it will cause the bearings to fail.
Sometimes the seal is just replaced without looking at anything, you should ask your mechanic.
Chances are there's a bearing failing, it will or has caused extensive damage. You Should have it checked ASAP.

2004 Dodge Ram with 129K ran differential low on fluid and it has a whining noise. Filled with fluid but the noise is still there and seems to be getting louder. What is making the noise in your opinion...

Could be pinion bearings, differential side bearings, axle bearings, ring and pinion mating, or any combination of the above. Very complicated stuff. Leave it to a pro.

Whine from rear differential when accelerating. the whine stops when I take my foot off the gas pedal.

when was the last time this was a replacement differential oil with additive MIGHT quieten this down.........however, this might be unlikely if the vehicle was not regularly serviced......if it only occurs whilst acceleratin this indicates wear on the main wheel/pinion......this COULD be an expensive repair....

Rear axel whining noise like a bearing when your accelerating an d just cruising at normal speeds on highway

This is due to internal wear in the differential and should be looked at by a technician you trust before it gets too bad and leaves you stranded.

1996 Audi A4 Quattro has a noisy rear differential

It's the wheel bearing. Guaranteed. Just replaced mine. Go to Audiworld tech articles for step by step instructions on how to test the wheel bearings. They must have been put in wrong last time or they just went out again.

Axcel rear noisy

Your carrier bearings and possibly the pinion bearings are the source if the noise is a low pitched grumble or gravelly noise that starts just about 20 mph and up. If it is louder when quickly changing lanes to the left, it is probably the right wheel bearing, and if it is louder when changing lanes to the right, it is the left wheel bearing. If it is a whine that is really annoying at 45-65 mph, your ring and pinion are probably worn beyond their design specification limit. If your U-joints are OK, but you can hear a loud clunk from the rear when you get on and off the throttle, you definitely have play in your ring and pinion. Have the cover removed and you can sheck this easily. I have worked on several Jeep Grand Cherokee differentials, and the ring an pinion has needed replacing on them all. A few had bad bearings, too. You should probably replace the bearings and the ring and pinion, because the labor is nearly the same and the parts are just a bit more. If you look through the forums on the www you will find many people that replaced the bearings to fix the grumble, only to finish the job and find out they also have the whine.
