What are the signs of a bad rear differential?

What Are The Symptoms of a Bad Rear Differential?

• Difficulty in handling. As the differential is the element which helps handle your vehicle in a turn, once it starts to wear out, precision is not something that will be on your side anymore.
• Tire damage.
• Vibrations.
• Whining Noises.
• Gear Grinding.

What causes a rear differential to go bad?

The first and most common is loss of differential oil which can cause gears inside the differential housing to break, grind, or even block the rear wheels. However, differentials can fail if they are pushed too hard which means that you have performed numerous burnouts, drag racing, and so on.

What does a failing differential sound like?

The most common sound of a failed differential is a whining noise. This is often due to poor lubrication within the differential, meaning there is a good chance that the differential fluid is leaking. If you spot a reddish fluid under the differential, there is certainly a leak.

How do you fix a rear differential noise?

How to fix a noisy differential: Replacing the differential fluid may stop the sound, or replacing a pinion or side seal may solve the problem. However, once the noise gets bad, rebuilding or replacing the differential may be the best way to fix the noise.

How much does it cost to rebuild a rear end?

A typical rear differential repair costs anywhere between $200 and $400. These typical repairs would include your bearing, seals, and fluid changes. Of course, when a gear change is required, that’s when things get pricey. $1,500 is just the minimum you can expect to pay for new gears.

Why is my rear end humming?

A humming noise is often caused by an incorrectly installed ring and pinion gear that needs to be adjusted. Incorrect installation of the ring and pinion gear prevents proper tooth contact and can cause rapid tooth wear and gear failure. Humming noise can also be due to worn out bearings, which need to be replaced.

How much does it cost to replace a differential?

The cost to replace a rear differential ranges from $200 to $400. However, if repairs included changing the gears, the price can jump significantly up to $1500 to $4500. Your vehicle’s rear differential is responsible for controlling the rotation of your wheels.

How long can you drive with a bad differential?

A rear differential service consists of removing the rear differential cover, cleaning any old fluid from inside the differential case, resealing the cover, and adding clean fluid. After a rear differential fluid change, most vehicles will go 20,000 to 40,000 miles before it’s due again.

What happens if you don’t change differential fluid?

If this fluid isn’t changed in the manufacturer-prescribed intervals, then it can get dirty and thick, which could damage the differential over time.

Can you drive with a bad rear differential?

Technically, you can drive with a bad differential, but it is not wise. The problem may get worse, to the point where it leaves you stranded somewhere. It can also cause damage to other surrounding components. It is smartest and safest not to drive with a bad differential.

What happens if you dont change differential oil?

Differential Fluid Change: What happens if you don’t change differential fluid? Differentials deal with moving parts that involve metal to metal contact that produces heat from friction. The said contact can also wear down its surfaces and eventually weakens its gears that can lead to failure.

How long can you drive with a bad rear differential?

After a rear differential fluid change, most vehicles will go 20,000 to 40,000 miles before it’s due again.
