rear differential replacement

The average replacement cost for a whole rear differential is between $1000 and $4000. Luckily, you can just repair it or replace it with a used differential, which will decrease the costs a lot. Most differential repairs will cost between $200 and $400 to repair.

Is it worth it to replace rear differential?

The truth is that sometimes replacing your rear differential will end up costing more than your car is actually worth. But that doesn’t mean you’re at a total loss. You can still junk a car with broken or faulty parts—and walk away with cash for it.

Can you drive with a broken rear differential?

You can still drive your vehicle with a bad rear differential, but it can cause severe damages. The problem may increase to the point of stopping you in the middle of nowhere. And, if you are asking about driving with a total broken differential, no, don’t do it unless you want to damage the entire drivetrain system.

How hard is it to replace a rear differential?

A complete rear differential replacement includes replacing the housing, gears, bearings, and seals. The average time it takes a certified mechanic to perform a differential rebuild at a shop is usually three to five hours. A rebuild on a commercial vehicle by someone without prior experience could take much longer.

What happens if my rear differential goes out?

Without it, you’d be dragging your outside wheel along the pavement whenever you turn. Typically, when the gears wear out – or the bearings fail – the differential will start to howl. You’ll hear something that sounds like a deep whistling sound that goes up and down in pitch as you go faster and slower.

What causes rear differential damage?

The leading cause of a differential failing is due to using the wrong lubricant type and specialty lubricants. Water can also be a culprit to a differential failing as it can enter through the vent or seals. This often happens when driving in high water.

How often should I change my rear differential fluid?

How often do I need to replace the differential fluid? Most manufacturers recommend that the differential fluid be changed every 30,000 to 60,000 miles. It is a messy job, and should be done by a licensed mechanic.

Does differential affect transmission?

When the differential doesn’t perform well, it creates metal-on-metal friction that wears down surfaces. The resulting heat weakens gears and can cause component failure and transmission problems. A bad differential makes the car harder to control turning corners, and that can be dangerous.

How do you know when your differential is bad?

Here are the most common bad differential symptoms to look out for:
Your vehicle is quickly going through oil.Difficulty steering.A loud front differential noise, such as the grinding of gears, clunking, or a “howling” sound.Rear differential noises. Extensive and inexplicable wear and tear on your tires.

Can a car run without the differential?

If there was no differential on the axle, both wheels would revolve at the same speed. Therefore, they would have tendency to cover the same distance as each other, which would result in tendency to go in a straight line. A car with rear wheel drive would push the front wheels, with their tyres skidding helplessly.

How long does it take to install a new differential?

On average, replacing a front differential is about a 3 hour job plus the cost of parts of course. More advanced types of differentials will also affect price.

How much does it cost to have a rear end rebuild?

Depending on the make and model of your car, as well as its condition, expect to spend between $1,500 to $4,000. The other factor is if you buy a new rear-diff or a used/rebuilt one. A used or rebuilt one will help you save money, but it won’t have the same warranty as a new one.

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 long can you drive with a noisy differential?

How long can you drive with a failing or noisy differential? You can drive with a bad differential, but not for too long. But generally, you can use it for a period between ten days to ten years.
