What happens when a rear differential fails?
If you find sidewall or outer tire wear on the rear wheels, it's a good indication that your differential might be failing. The differential allows the tires to spin at different rates during cornering, and when it fails, the gears grind, causing the tires to turn at the same rate, which wears out the tires.
Is it worth fixing rear differential?

How to tell if rear diff is going out?
Vibrations While Accelerating. If rear-diff problems go untreated, it may damage other components of the drivetrain, like the universal joins. When these become worn, you may notice excessive vibrations (especially while accelerating). This is one of the earliest symptoms that suggest your diff is going out.
What does it mean when diff fluid is leaking?
If the diff fluid is leaking, there’s likely a worn seal that needs to be replaced. When this happens, you may notice a gray or brown liquid under the rear of your car.
What is a limited slip diff?
A limited-slip diff acts just like an open one, under normal conditions. However, where a limited-slip diff takes things a step further, is that it can limit the amount of power it sends should a wheel lose traction. Meanings it not only provides better stability but increases safety as well.
Why does my differential blow out?
Tire Damage. Since the differential helps keep your tires rotating at optimal speeds, if it’s not working, you may notice inside tire wear. This will most likely lead to a blowout eventually if the tire threads sustain too much damage.

Rear Differential Leak
The rear differential leaks of your vehicle could occur in some of its parts. Rear differential leaking can come from the pinion seal, where it is connected to the driveshaft. But it could also come from the rear differential cover or at the axle seals.
How Important Is the Rear Differential?
The rear differential performs an important role in the efficient operation of your car. It has a set of mechanisms that are connected to the driveshaft. Also, the rear differential transfers the engine’s power to the rear wheels of your car.
More on Rear Differential
For vehicles with rear-wheel drives, the differential is located at the rear. You can find inside the differential housing a thick dark fluid that acts as the lubricant of the differential gears. For front-wheel drive vehicles, the differential is usually a part of the transmission housing. It uses the same fluid used by the transmission.
Causes of Differential Leaks
So, if you notice traces of oil underneath your car directly under the differential, you have to know why it is there. If you don’t have enough fluid in the differential, your car will not run smoothly. But why will this fluid leak from the differential?
How to Fix Differential Leaks
If you discover fluid leaks in your differential, it is not the end of your rear differential. However, fixing this kind of problem is not usually a DIY project. Professional mechanics usually perform them. Here are the steps:

What happens when you corner a car?
When you corner in your car, the right and left wheels take different paths. The inside wheels require a smaller turning radius, meaning fewer revolutions are needed. Without a differential, the tires would need to spin at the same speeds, even though they need to be on different paths.
What is a drive wheel?
Driven wheels are the ones that receive engine torque to drive the vehicle. Both front- and rear-wheel drive vehicles use two drive wheels. These will have a single differential. On a front-wheel drive vehicle, there is a transaxle. This single unit combines the transmission with the differential.
