What does a bad rear differential sound like?

Can a bad 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 change a rear differential? Rear 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 hard is it to replace a rear differential? A complete rear differential replacement includes replacing the housing, gears, bearings, and seals.

A rebuild on a commercial vehicle by someone without prior experience could take much longer.
How long does a rear differential last?
The lifespan of a differential depends on various factors, such as driving habits, level of maintenance, the type of oil used during servicing, and many more. Under regular use and proper maintenance, differentials should last 150,000 miles or the life of a vehicle.
Can a bad differential cause power loss? Depending on the vehicle and the issue the rear differential has, what happens when the rear differential goes out while driving varies in severity. If you have broken gear teeth or badly chipped teeth then you will experience a soft of “skip” in power or vibration that increases with speed.
How much does a diff swap cost?

Is rear differential service necessary? 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.

A differential assembly is about 70lbs.
How do you service a rear differential?

The job itself is actually pretty easy, however, if you’re planning to change your vehicle’s differential fluid at home, then it can get messy.
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.
What does a slipping differential feel like?
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.
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.
Can you repair a diff?
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.
What can cause a differential to break? 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 do you know when to change your differential 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.
Can low differential fluid cause vibration? Differential vibrations are almost always caused by a lack of lubrication. Sometimes water gets into the differential. If that’s the case, make sure your breather is intact and not in a place where water can get in. If your differential is low on oil or has water in it, get the water out, top off the fluid and recheck.
