What happens when your differential goes out?
Typically, the differential will start giving strange noises when it goes out, or when the bearing fails. You will hear a whirring noise, whining noise, a growling noise, or howling noise. The noise will increase or decrease as you accelerate or decelerate the vehicle. Sometimes, you may not hear the noise when you step on the throttle panel.
How do I know if my rear differential is bad?
Typically, the differential will start giving strange noises when it goes out, or when the bearing fails. You will hear a whirring noise, whining noise, a growling noise, or howling noise. The noise will increase or decrease as you accelerate or decelerate the vehicle.
Is it possible to avoid a stock differential failure?
Constant stress to the axles is a problem. Especially when running wider tires and doing tighter turns. Sadly, this might not be avoidable, but it mostly depends on your driving style and your car. A stock differential failure is rare, especially if it is being maintained properly.
Is a compromised differential affecting your safety?
Many common problems with differentials can snowball into major headaches if you don’t deal with them in a timely manner. More importantly, a compromised differential can negatively impact your safety when you’re behind the wheel by making it difficult to turn.
Can you drive with a bad differential?
You can still drive your vehicle with a bad rear differential, but it can cause severe damage. 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.

Is it worth fixing a 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.
What happens if you drive with a bad rear differential?
Can You Drive With A Bad Rear Differential? Yes, you can drive with a bad rear differential as long as the issue does not cause one wheel to spin faster than the other. If this is the case, then your car will not be able to move in a straight line and you will have to pull over and call for assistance.
How much does it cost to fix a differential?
Most differential repairs will cost between $200 and $400 to repair. Of course, this depends on the severity of the defect and what parts need to be replaced. For a rebuilt differential, you might need to spend between $400 and $1,000. On the other hand, replacing a differential costs $1,000 to $2,000 on average.
How much does it cost to replace a rear differential?
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 rear differential cause transmission problems?
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 long does it take to replace a rear differential?
three to five hoursRear differential bearing replacement. There are side bearings and a pinion bearing which can pit or deteriorate, causing your rear differential noise. These bearings are part of a rear differential overhaul, taking three to five hours to complete.
How long do differentials last?
The oil needs to be changed every 30,000 to 50,000 miles, unless your owner's manual states otherwise. The differential is a part in your vehicle that compensates for the difference the inner wheel and the outer wheels travel when you turn a corner.
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.
What causes differential failure?
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.
Can a differential be repaired?
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 does a bad rear differential sound like?
Clunking, rumble, or howl when cornering: This may indicate a problem with the spider, or side gear. Depending on how extreme the sound, it could mean there has been a leak of lubricant, a worn spider gear, or even a broken gear.
What causes rear differential to go out?
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.
What does a bad rear end sound like?
A knocking or clicking sound may be due to the splines on the axle shafts being worn out, in which case the defective shaft has to be replaced. Another reason for this may be chipped teeth on one or more of the gears in the differential. Again, they'll need to be replaced.
Can a rear differential be repaired?
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.
Why does my differential fail?
You might notice an oil puddle under your vehicle or oil spots on the differential housing because the wrong oil type can cause leaks. Or you might perceive a burning smell while driving.
What happens if your differential is worn out?
Handling your vehicle may become problematic if your differential is worn out, resulting in an accident.
Why does my ring and pinion make a noise?
A ring and pinion gear failure is usually caused when worn, scored, or out of adjustment. Furthermore, when there is too much clearance or backlash between ring and pinion, you will hear a clunking noise when shifting from park to drive. You can use a telescope to detect whether it is the differential or rear axle problem that is causing the noise. ...
How to tell if your differential is bad?
Instead of the wheels turning at the same rate, a differential offers more precise control over your vehicle. If you start hearing weird noises from the wheels or start feeling unusual vibration, check it out. They are likely to be the signs of a bad differential.
Where do you check for leaks in a differential?
First, you need to make sure there are no leaks around the rear differential gasket. Next, check for leaks in the rear axle area. Leaks can occur at the pinion gear seals, and when the leak is bad enough, dirt and oil will accumulate right below the carrier, pinion gear, or at the brake system areas.
What is differential in motor vehicle?
A differential has one significant function; to transfer power from vehicle transmission and engine to individual wheels. The differential allows the driver to optimize the handling and control of the vehicle. It offers more precise control over your wheels, instead of the wheels to be turning at the same rate.
What causes differential overheating?
Differential overheating: Differential overheating can be caused by using the wrong type of oil, lack of lubrication, worn gears, excessive bearing preload, backlash between the ring and pinion, overloading when hauling a heavy trailer, or loading equipment.
Why do you need a differential?
A differential helps prevent these issues by allowing each of your vehicle’s driven wheels to spin at a different speed.
Can a faulty differential cause a car to lock up?
A faulty differential can also cause your car’s wheels to lock up, and this can put you in a dangerous situation if it happens while you’re in traffic. A differential can experience a wide range of problems, but these issues are fairly easy to spot.
Can a compromised differential cause headaches?
Avoid Serious Consequences With Attentive Repair. Many common problems with differentials can snowball into major headaches if you don’t deal with them in a timely manner. More importantly, a compromised differential can negatively impact your safety when you’re behind the wheel by making it difficult to turn.
What does it mean when your differential is locked?
If your differential is locked you may also experience tire scrubbing, which is the sound of your tires gripping and slipping in quick succession . Depending on the rubber compound, this may sound like a rapid squeal or a chirp. There will likely be some vibration to the rhythm of the sound.
What is differential in a car?
A differential is the part of a vehicle’s powertrain that allows two wheels to turn at different speeds. Differentials have one input and two outputs, with each output going to an axle or drive shaft which then connects to a wheel.
Why do two tires slip?
This would cause one or both tires to slip, causing loss of traction, excessive tire wear, and additional stress on other powertrain components. The difference in speed between the two tires is due in part to the vehicle’s track width (that is, the distance between the left and right wheels). The greater the track width and the tighter ...
What happens when a tire slips?
The basic idea is that when a tire slips, the maximum wheel speed of a slipping tire is limited. Torque is then transferred or multiplied to the opposite tire that still has grip. Ideally, this allows a vehicle to keep moving forward even if one tire has little or no grip.
What is a limited slip differential?
A limited slip differential is a middle ground between an open differential and a locking differential. These are typically found on sports cars and higher end luxury cars. There are many different types and implementations of limited slip differentials.
Why does my differential drive shaft vibrate?
4) Vibrations. If the universal joints of your differentials get too worn out, the drive shaft will start to vibrate. You will feel the vibrations even more as you step on the gas pedal to accelerate your vehicle. The vibrations will get even worse if there is a differential fluid leak.
How many differentials are there in an all wheel drive vehicle?
All wheel drive vehicles have three differentials: a front, rear, and center differential. The center differential splits the torque between the front and rear differential inputs, which each then split the remaining torque from left to right.
