What does a failing rear differential sound like?
A whine during deceleration may mean there is a bad or loose pinion bearing. A howl during acceleration may indicate the same problem. Rumble or whining sounds only at speeds greater than 20 mph could be a sign of a worn carrier bearing. The sound may change while cornering.
What sound does a bad rear differential make?
Regular clunking every few feet can also be an indicator of a broken pinion gear and/or chipped and damaged ring gear. Overly worn out bearings tend to make a howling noise when they do not properly support the gears. Rumbling while turning, on the other hand, is a sign of bad wheel bearings.
Does the differential affect the transmission?
Your vehicle's differential is a critical part of its drivetrain. Positioned midway between the driving wheels, it works with your transmission to get the car moving.
Can I drive without a differential?
If there was no differential on the axle, both wheels would revolve at the same speed.

Can you drive a 4WD truck without a front or rear driveshaft? Yes, this is possible, if you drive a traditional 4WD with a lockable center differential. Remove the damaged drive shaft and lock the center differential. This will allow the transfer box to transfer power to the front or rear driveshaft.
What happens when a rear differential locks up?
A locking rear differential, once engaged, does not allow both wheels to spin freely. By ensuring that both wheels spin at the same rate, and applying unequal torque to each tire on the axle, the risk of losing traction or spinning out decreases dramatically.

A well-functioning differential ensures that your vehicle corners the way it was intended. If it is failing, it is going to change the cornering ability and create an unstable drive.
Why does my differential make a humming noise?
When the differential wears down, the gears can start to grind. This condition can also create a humming noise from the gear grinding. As you accelerate, the humming grind will get louder. If caught early enough, a simple fluid change might be all that is needed.
What does it mean when a differential is leaking fluid?
The most common symptom associated with a defective differential is a whining sound. In many cases, it simply means that the differential components might not be properly lubricated. It could also mean that the differential is leaking fluid, which will lead to premature wear.
Do four wheel drive vehicles have a front differential?
In addition, the front and rear differentials will split that torque further between the left and right wheels on that axle. Typically, a four-wheel-drive vehicle will have a front and rear differential. However, instead of using a center differential, most of these vehicles contain a transfer case in its place.

Why do you need to lubricate your rear differential?
Just like any components in your car that grinds against each other, lubrication is very important for your rear differential. The gears inside the differential are bathed in gear oil, reducing friction between the gears which in turn prevents overheating. Similar to your engine’s oil, the oil will break down over time, and they will collect metal filings from the gears. As a result, they lose lubricity and increases friction between the gears. When this happens, it could cause more damage to your differential and your car if left unserviced.
What does it mean when a rear differential makes a whining noise?
Whirring or whining noises. A rear differential that’s in need of service (or repairs) will make loud whining noises. The noise is high-pitched and tend to appear at speeds above 15mph, and it might vary depending on the speeds and load that’s put onto the differential.
What is the role of a rear differential?
In a nutshell, the rear differential’s role is to transfer power from your transmission (or transfer case if you have an all-wheel or four-wheel drive vehicle) onto your rear wheels. More importantly, the rear differential contains a set of gears that allows your rear wheels to rotate at different speeds.
Why is my differential leaking?
Leaking differentials can also be caused by leaky side seals. The side seals are there to stop the fluid from leaking onto the rear brakes, which can be dangerous. Repairing the side seals is more time-consuming and challenging, as you will need to remove the axle shafts that connects the differential onto the wheels.

How does a differential work?
The differential receives engine power from the driveshaft and splits the power input between two axle shafts, which drive the wheels on an axle. On a rear-wheel drive, there’s one differential on the rear, and on a four-wheel-drive vehicle, there is a front differential and a rear differential. An all-wheel-drive vehicle is a little different.
How long do differentials last?
One of the more common failures is simple wear and tear, though in normal use, and with scheduled maintenance, a differential can last as long as the vehicle.
