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 much does it cost to fix a diff on a car?
A complete overhaul, including to replace your diff, is likely set you back between $1,500.00 and $2,800.00 inclusive of both parts and labour.
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.
How long does it take to replace 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.
What happens if rear differential goes out while driving?
Q: What happens when your rear 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.
What does a rear differential problem sound like?
The most common rear differential noise is a whirring sound, although it’s not unheard of to have a clunking or banging sound as you accelerate. If you do hear a whirring noise, it’s going to remind you of what a worn-out wheel bearing sounds like.
Can you repair a diff?
The rear differential cover is typically silicone or rubber and can deteriorate and leak. It’s the easiest to repair – all that’s required is removing the rear differential cover, cleaning the sealing surface, and resealing the cover. It’s all done in less than an hour. Rear differential pinion seal.
How much does it cost to swap a 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 is differential service?
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.
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.
How can you tell if the differential is bad?
Here are the most common bad differential symptoms to look out for: Your vehicle is quickly going through oil. Difficulty steering. A loud front differential noise, such as the grinding of gears, clunking, or a “howling” sound. Rear differential noises. Extensive and inexplicable wear and tear on your tires.
What causes a differential to go bad?
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.
How long can you drive with a noisy differential?
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.
Is the differential part of the transmission?
A differential is part of the front and/or rear axle assembly. The differential fluid or oil in transaxles and axles should be changed as part of a preventive maintenance schedule. It’s part of your transmission service. Some four wheel drive vehicles require changing the axle oil every 30k miles.
What does a broken 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.
Does changing differential oil 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.
Where is the differential located?
Where is the differential located? Explanation: The differential used to incorporate the speed of the rear wheels and front wheels during turning. It is located between the transmission and rear axle.
What causes a rear differential to leak?
The most Common Causes of Differential Fluid Leaks There is a number of causes for differential leaks which you need to have repaired as soon as possible before you damage the gears inside your differential housing. The cause for a leak could be a leaking gasket, a leaking pinion seal or a differential side seal.
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.
