How serious is a differential leak?

The differential fluid lubricates the ring and pinion gears which transfer power from the driveshaft to the wheel axle. If your vehicle experiences differential fluid leaks, the fluid lubricating these gears will run low and as a result, the gears can be seriously damaged.

What to do if rear differential is leaking?

Different oil leak repairs include: Rear differential gasket replacement. The rear differential cover is typically silicone or rubber and can deteriorate and leak. It’s the easiest to repair – all that’s required is removing the rear differential cover, cleaning the sealing surface, and resealing the cover.

How much does it cost to fix a leaking differential?

Most specialists would put the repair cost somewhere between $200 – $400 for fixing an oil seal, leaking differential gasket, or lashing, and between $1000 – $2,000 if differential housing work is needed (such or replacing the ring and pinion gears).

Can you drive with a damaged differential?

Driving with a bad differential can also result in further damage to other close components of your car. Therefore, it would be best not to drive with a bad differential; instead, get an auto mechanic to fix the problem before driving your vehicle again.

Is it safe to drive with a rear differential leak?

Depending on the amount of oil seeping through the gasket, this may leave noticeable traces of oil on the undersides of the differential housing. A seeping differential will usually be okay to drive for a while, however, it will eventually progress into a full on leak as time goes on.

How much does a rear differential rebuild cost?

If new gears are needed the price can be at least $1,500. Going to the worst-case scenario, if the differential is beyond repair, you’ll need the component to be replaced altogether. You can expect a rear differential replacement to cost up to $4,000.

Can a vehicle run without 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 replace a rear differential?

three to five hours
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.

How can you tell if the differential is bad?

Symptoms Of A Bad Rear Differential
  1. Vibrations. A bad differential can cause vibrations that increase in intensity as you speed up and reduce as you slow down. …
  2. Grinding Gears. Grinding gears is another significant sign that your differential is failing and that the gears are wearing themselves out. …
  3. Whining Noises.

Why differential is needed for safe operation of a vehicle?

The differential is a system that allows the drive wheels to turn at different speeds, which is required when the car is negotiating a turn. In a turn, the outside wheel must travel farther, which means it must travel faster than the inside wheels.

What is the main purpose of differential?

A differential works with the transmission to deliver power from the engine to the axle that turns the wheels. It also helps your vehicle turn properly. In order for your vehicle to turn, the outside wheels must turn faster than the inside wheels.

Do front wheel drive cars have differential fluid?

Rear-wheel drive vehicles use a rear differential but no front differential. A front-wheel drive vehicle will use a transaxle, which is part of the transmission. Rear differential fluid is used for rear-wheel drive cars. Trucks use the same fluid in both the inter-axle differential and the rear differential.

Can you turn without a differential?

Without a differential, two wheels on an axle will want to spin at the exact same speed. During a turn, the inside wheel will “scrub” by spinning over the surface of the asphalt while making sporadic contact. In a best-case scenario, the vehicle can turn while losing minimal tire tread to scrubbing.

Is the differential part of the transmission?

The differential is a set of gears that transmits engine power to the wheels, while allowing them to turn at different speeds on turns. With front-wheel-drive (FWD), the differential is alongside the transmission inside a housing, and the unit is called a transaxle.

How often should I change diff fluid?

The recommendation of most car manufacturers is that you change your rear differential fluid about every 30,000 miles to 60,000 miles. Look at the owner’s manual of your car to find the exact mileage amount. This interval gets shorter the harder you drive your vehicle.
