The process of entirely replacing a rear differential at an auto repair shop usually takes three to five hours. A rear differential can last anywhere from 50,000 to 200,000 miles, depending on what type of driving conditions it’s subject to and how well it’s maintained.

How much does it cost to replace a rear end 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.
How much does it cost to service a rear end?
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.
How long does a differential change take?
Our certified technicians can perform this service in about 10 minutes – while you wait in the convenience of your car. Plus, you could save between 30% to 50% versus the dealership. Many auto manufacturers recommend replacing differential fluid at regularly scheduled intervals. Check your owner’s manual for details.
What happens if rear differential goes out while driving?
Damage To The Tire The differential allows the tires to spin at different rates during cornering, and when it fails, the gears grind, causing the tires to turn at the same rate, which wears out the tires.
What causes rear differential whine?
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 rear differential noise sound like?
Hearing an increase in the level of humming noises or gear grinding is a way of knowing almost for sure that you have a worn out differential. Usually the humming gets louder under acceleration. When this occurs it’s best to check the condition of your differential and replace if it’s in a rough condition.
How many hours does it take to rebuild a front differential?
On average, you can expect your mechanic to complete this repair in three to six hours, depending on your vehicle. Your front differential is unlikely to need replacing except in older cars or when damage has occurred that causes it to leak or wear down more rapidly.
How much should differential service cost?
The Average Cost to Change Differential Fluid Is $79-$93. This price range is based on national averages for all vehicles and does not factor in taxes, fees, or your particular make and model.
Is rear differential service necessary?
Is differential service necessary? Yes! The differential uses oil, thicker than the oil that goes in the engine. Changing the oil in the differential is as important as the engine oil change because over time, the oil wears thin and becomes contaminated.
How often should differential fluid be changed?
Generally speaking, differential fluid should be changed anywhere from every 30,000 miles to 60,000 miles.
Does changing rear differential fluid make a difference?
In most cases, you will need to change differential fluid every 30,000 to 50,000 miles. It’s important to stay on top of changing differential fluid because metal-on-metal contact creates heat from friction. It also weakens gears and wears down surfaces. That can lead to differential failure, which is a costly problem.
How much does it cost to change diff oil?
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.
Which grade of oil is used in differential?
(2) Differential Gear Oil Automotive differential uses hypoid gears exposed to severe operating conditions and it is applied with impact load in driving. Therefore, API GL-4 or 5 single-grade gear oil designed to maintain high viscosity at extreme pressure is used.
What makes rear differential go bad?
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 if you have a bad rear differential?
A bad rear differential will develop a series of strange noises. It could be a whirring noise, a humming noise, growling noise, or a whining noise. However, the most common sound of a bad differential is whining or howling noise, indicating a damaged or worn-out ring and pinion gears.
Why does my rear end clunk?
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.
What does a worn ring and pinion sound like?
A “whirring” sound generated by unloading via deceleration from most any regular road speed can likely be traced to pinion bearing failure or poor pinion bearing preload. This malady is often diagnosed as a bad ring and pinion gear.
What does low differential fluid sound like?
A common symptom of differential low on a fluid is a weird humming, howling, whining, and whining noise from either front or rear differential. You’ll notice a gradual change in these noises when accelerating, decelerating, and when taking corners.
Why is my car making a loud humming noise when I accelerate?
Your car makes a humming noise when accelerating What it could mean: This is most likely a wheel bearing noise. It’s often mistaken as an engine noise and one way you can tell is to watch your RPM gauge. As you accelerate, the RPM and speed gauges rise.
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 a rear end last?
An excellent rear axle should go for up to 100000miles. The mileage also applies to those semi-trucks that carry heavy loads. However, expect them to wear with time since they constantly flex and rotate to accommodate the rough road.
How many hours does it take to rebuild a rear end?
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.
How much does a diff rebuild cost?
Replacing bearings and seals – carrying out a diff repair – will usually cost you between $400.00 and $650.00. If the problem is the transaxle then you’re looking at twice that cost.
How long does it take to rebuild an axle?
It might just take an hour to fix one side of the axle once you take it to a professional. Regardless of whether it is the front or the back axle, installing it and fixing it could take an hour. Working in an axle replacement shop typically takes 1.5 hours on each side.
