How does a bad differential sound? 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.
Similarly, What happens when a differential fails? When a rear differential fails, it can cause vibration, noise and fluid leaks that impact a vehicle’s acceleration and driveability. A driver should consult a certified mechanic to deal with a bad rear differential and prevent further damage to the vehicle’s driving systems.
How do I know if my differential fluid is low?
If the gear oil runs low or becomes excessively dirty, it can cause the gears to whine or howl as they turn. The whining or howling is caused by lack of lubrication and may increase in volume as vehicle speed increases.
What happens if you dont replace rear differential fluid?
Most differentials need a fluid change at about 50,000 miles. If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.
How much does it cost to fix a differential?
Average Differential Repair Cost
These are light repair jobs that will cost between $200 to $400, depending on the make and model of your vehicle. But if you have more extensive damage to your differential that requires it to be dismantled or overhauled, then you are looking at about $400 to $800 in repair costs.
What does a worn differential sound like? A whine during deceleration may mean there is a bad or loose pinion bearing. A howl during acceleration may indicate the same problem. Rumble or whining sounds only at speeds greater than 20 mph could be a sign of a worn carrier bearing. The sound may change while cornering.
What does a noisy differential sound like? Regular “clunking” or loud “clicking” every few feet may indicate a broken ring or pinion gear tooth. “Clunking or clicking” when starting to move or getting on and off the gas might be loose yokes, bad u-joints or worn transfer case or transmission parts.
How much does it cost to fix the differential?
These are light repair jobs that will cost between $200 to $400, depending on the make and model of your vehicle. But if you have more extensive damage to your differential that requires it to be dismantled or overhauled, then you are looking at about $400 to $800 in repair costs.
Why would a rear differential fail? The leading cause of a differential failing is due to using the wrong lubricant type and specialty lubricants. … When water enters it will emulsify the differential lubricant and result in rusting on gear and bearing surfaces. Seized U-joints that result in vibration can cause differential failure as well.
Can you fix 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.
How much does it cost to change differential fluid? Differential Fluid Change Cost
The fluid itself can cost between $30 and $80, and labor will run between $40 and $70. All together, you’re looking at somewhere in the range of $70 to $150 to change your differential fluid depending on your vehicle, where you take it, and how much differential fluid it needs.
What causes rear 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.
How much does it cost to fix a rear differential?
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.

How do you know when to change your differential fluid?
Usually, differential fluid is changed after every 30k to 60k miles driven. This is a tough job, so must be handled by an expert technician. Only an experienced mechanic can properly wipe out the old different fluid from your vehicle’s drive-train.
Is it worth fixing a 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 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.
What happens if your differential goes out?
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. Sometimes it’ll go away when you step on the gas.
How do you fix a noisy differential? How to Quiet Differential Whine
- Prep the area.
- Replace Differential Fluid.
- Replace the seal.
- Test the Vehicle.
- Inspect rear differential gasket, pinion seal, and side seal.
- Clean the housing.
- Replace broken parts.
- Lubricate and re-install axle into differential.
What causes a rear differential to go bad?

How long will a noisy diff last? Final Words
To reiterate, in terms of how long can I drive with pinion bearing noise — it can be ten days or ten years. This will highly depend on the condition of the bearing. If it is worse, get it replaced as soon as possible.
How do you check differential bearings?
What happens when your rear differential goes out? 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. Sometimes it’ll go away when you step on the gas.
