How Much Does It Cost To Rebuild A Rear Differential?


The average replacement cost for a whole rear differential is between $1000 and $4000. 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.

How long does it take to rebuild 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.

Does changing differential fluid make a difference?

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.

Do I need front and rear differential service?

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 can you tell if your rear differential is going out?

Symptoms Of A Bad Rear Differential

  • Vibrations. A bad differential can cause vibrations that increase in intensity as you speed up and reduce as you slow down.
  • Grinding Gears. Grinding gears is another significant sign that your differential is failing and that the gears are wearing themselves out.
  • Whining Noises.
  • How much does a diff swap 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.

    How much does it cost to replace a rear end?

    Depending on the make and model of your car, as well as its condition, expect to spend between $1,500 to $4,000. The other factor is if you buy a new rear-diff or a used/rebuilt one.

    How much does it cost to change gears in a rear end?

    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 much does a used differential cost?

    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 happens if you don’t change your 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 long should a rear differential last?

    Under regular use and proper maintenance, differentials should last 150,000 miles or the life of a vehicle.

    Is axle fluid the same as differential fluid?

    There is a LOT of torque going through your axles, and the gears inside are under a lot of pressure! In order to last, they need to be properly lubricated. Every front or rear axle is filled with a special oil (also called differential fluid, or gear oil) that takes care of this.

    How long does a differential service 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.

    How often should diff oil be changed?

    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.

    What does rear differential service include?

    A rear differential service consists of removing the rear differential cover, cleaning any old fluid from inside the differential case, resealing the cover, and adding clean fluid. After a rear differential fluid change, most vehicles will go 20,000 to 40,000 miles before it’s due again.

    What does a failing differential sound like?

    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.

    What causes a rear differential to 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.

    What does a rear differential problem 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 is a quick change rear end?

    A quick change rear end is a part that is made for racing and as such, they have replaceable components for race damage repair. If you bend an axle tube, it is easy and cost affordable to buy a new axle tube rather than buying an entire stock housing.

    Is differential cost a relevant cost?

    Definition: Relevant cost, also called differential cost, is a management accounting term decsribing costs that pertain to a particular decision. Relevant costs will vary based on the context of the decision, such as an omnichannel business analysis by a multi-platform retailer.

    What happens if your rear end goes out?

    Without it, you’d be dragging your outside wheel along the pavement whenever you turn. 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.

    Are 3.73 or 4.10 gears better?

    4.10s are going to accelerate faster and decelerate faster on lift. However the trade off is greater fuel consumption per mile driven and higher engine speed per given road speed. In basic terms the 4.10s will feel quicker and 3.73 will feel faster.

    Is 3.73 gears good for towing?

    For towing, the 4.10 is better. For a heavier load, I would agree that the lower gearing is better. For a light load (4k lbs), 3.73’s would do just fine. If you foresee towing heavier loads in the future (getting a larger TH, etc), then 4.10’s would be the better choice.

    How much does it cost to install diff gears?

    price is $300 ea. If you want them taken out and installed at the shop along with the setup I would assume $600-$700 ea. This is with no parts.

    How do you find the differential price?

    For the company to know if the new selling price is viable, it calculates the differential cost by deducting the cost of the current capacity from the cost of the proposed new capacity. The differential cost is then divided by the increased units of production to determine the minimum selling price.

    What is the difference between a sunk cost and a differential cost?

    Sunk costs—costs incurred in the past that cannot be changed by future decisions—are not differential costs because they cannot be changed by future decisions. Direct fixed costs—fixed costs that can be traced directly to a product line or customer—are differential costs and therefore pertinent to making decisions.

    How do you know if you need differential fluid?

    A burning smell from your differential or gearbox is another sign you need near differential oil. The smell may be coming from oil leaking out of an old seal — you may even notice a reddish stain under your car’s parking spot. The burning smell might also be a result of an overheating gearbox from poor lubrication.

    How much does a transfer case fluid change cost?

    A mechanic will be able to complete a transfer case fluid replacement, which is used in four-wheel and all-wheel drive vehicles to ensure the axles are cool and turning smoothly. It should be replaced every 30,000 miles and usually costs $75 to $160.

    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.

    Can I use Lucas in my differential?

    A: Yes, In addition to being great for your engine, you can also mix it 25% / 75% a manual transmission and 50% / 50% in the differential. Lucas Oil Stabilizer blends with any petroleum-based or synthetic oil, and is formulated for gasoline or diesel engines.

    Changing the fluid in a differential is almost as easy as changing the oil in the engine. However, the process can differ between vehicles since some differentials only have two plugs — one for filling the fluid and another for draining it – while other vehicles require you to remove the housing cover.

    How much rear differential fluid do I need?

    Fill to the Brim

    The weight and capacity will be listed in your owner’s manual; your differential will usually hold as much as 3 quarts. Be sure to read that manual, though, because some limited-slip differentials require a secondary friction-modifying additive.

    How do you clean rear differential?

  • Drain.
  • Remove cover.
  • Spray, clean, rinse, whatever all the innards.
  • Wipe and dry.
  • Inspect.
