Whether it is worth fixing a rear differential depends on the severity of the issue, the cost of the repair, and the age/condition of the vehicle. While fixing a rear differential typically involves significant labor costs, it may still be worthwhile if the repair will help ensure the vehicle runs reliably and safely for many years to come.
If the vehicle is older and the differential is beginning to fail, then it may be worth it to put the money into repairs now so that you won’t have to worry about any serious breakdowns in the future.
Additionally, if you plan on keeping the car for a long time, then investing in the repair could help to increase its resale value. On the other hand, if the differential is near the end of its useful lifespan, then it might not be worth investing in the repair in case the problem reoccurs soon afterwards.
Ultimately, the decision of whether to repair a rear differential or not should be based on its condition, the cost of the repair, and the value of the vehicle.

How much does it cost to replace rear differential?
The cost to replace a rear differential will vary based on the make, model, and year of the vehicle, as well as the labor involved and the type of parts used. In general, the average cost of replacing a rear differential ranges from $800 to $1600, with some vehicles costing as much as $2500.
This usually includes the labor costs involved in inspecting, diagnosing, and replacing the parts. It is essential to shop around and get a second opinion to ensure that you are getting the best rate and that the job will be done correctly.
What happens if you don’t fix a differential?
If you do not fix a differential, a variety of problems can occur. These include reduced fuel economy, decreased performance, accelerated wear of engine components, and damage to the differential itself.
If the vehicle is a front-wheel drive, steering and braking problems can also occur. If only one wheel is affected by the malfunctioning differential, it will be very difficult to control the vehicle in corners, as the wheel on the inside of the turn won’t rotate as quickly as the outside wheel, resulting in loss of traction and control.
Eventually, the components inside the differential will become worn down or broken, and will need to be replaced. As a result, it is highly recommended that you fix a differential as soon as possible to avoid further damage.
Can you drive a car with a broken rear differential?
No, you should not drive a car with a broken rear differential. Driving with a broken differential can cause your car to be inoperable and cause a lot of damage to other components, such as the drive shaft, transmission, tires, and axles.
Additionally, depending on the extent of the breakage of the differential, it may be unsafe to drive. The differential is responsible for distributing power to the wheels and if it is not working correctly, your car may not be able to move in a straight line and you may not have control over the steering wheel.
It is always best to have a professional diagnose the issue so it can be resolved in a safe and effective manner.
Is it cheaper to rebuild a differential?
In some cases, it is cheaper to rebuild a differential than to buy a new one. This depends on several factors, such as the extent of the damage, the quality of the parts that need to be replaced and the availability of those parts.
It also depends on the labour costs associated with the rebuild. If a heavy-duty differential needs to be replaced or repaired, it might be more cost-effective to buy a new one as the cost associated with parts and labour is likely to be expensive.
However, in most instances, rebuilding is the more cost-effective option, as the repair work will be more tailored to the needs of the vehicle and less expensive than purchasing a new differential. Additionally, rebuilding your differential eliminates the need for purchasing a new one, which can result in considerable savings.
What causes a rear differential to fail?
Rear differential failure is usually caused by a lack of lubrication, allowing the gears inside to grate against each other. If a rear differential is not serviced according to the manufacturer’s instructions and the correct grade of lubricant and gear oil is not used, the differential can become dry and the gears can become damaged or stripped.
Other causes of rear differential failure include the buildup of dirt and debris inside the differential, overloading the differential with excessive weight, or the sudden jolt caused by going over large bumps or potholes.
In some cases, it may be a defect in the differential or the use of the wrong grade of oil or lubricant. Replacing the fluid in the differential is the best way to prevent failure and ensure that the gears do not become damaged by drying out.
How long does a rear differential take to replace?
Replacing a rear differential can take anywhere from two to four hours, depending on the type of vehicle and the extent of the repair. The complexity of the rear differential is one factor that will affect the amount of time needed to replace it.
If a full replacement of the differential requires removal of other components such as the drive shaft or suspension links, then this can add significantly to the amount of time needed to complete the job.
Additionally, the tools, skills, and experience of the mechanic will affect how long the replacement takes. Finally, if the differential has suffered any damage that requires extra parts or special tools, then this could also extend the amount of time needed to complete the repair.
How often should rear diff be changed?
Typically, rear differential fluid should be changed every 30,000 to 60,000 miles, but it does depend on the vehicle make and model. The rear differential fluid should be replaced as recommended by the manufacturer for best performance and to prevent premature wear of the differential system.
Regular servicing of the rear differential fluid will ensure the life of the differential system and maximize performance. If the vehicle has been exposed to extreme operating conditions such as deep water crossings, off-road use, frequent towing, etc.
, then the rear differential fluid should be changed more frequently. Additionally, if the rear differential fluid looks dark or becomes contaminated, then the fluid should be replaced immediately regardless of mileage.
What happens if rear differential goes out while driving?
If the rear differential goes out while driving, it will result in limited or no power delivery to the rear wheels. One of the most common symptoms of a bad rear differential is loud noises coming from the rear end of the vehicle.
Without power delivery to the rear wheels, your vehicle may pull to one side when accelerating, or you may experience difficulty turning. Driving an automobile with a bad rear differential can cause further damage to the drivetrain and ultimately lead to a breakdown.
In order to prevent this, it is important to diagnose and repair the problem as soon as possible. Common causes of rear differential failure include insufficient lubrication, damage to the gears, and worn or broken components.
To assess the damage and its cause, it is best to take the vehicle to a qualified mechanic who can evaluate the components and repair any necessary parts.
How much should a rear differential service cost?
The cost of a rear differential service will vary depending on the type of vehicle and its condition. Generally speaking, a basic rear differential service will typically cost between $100 and $200 depending on labor costs.
This service will include draining and refilling the differential fluid to the manufacturer’s recommended level, as well as checking for wear and tear. During this type of service, the expert performing the maintenance will also inspect the rear differential for any signs of wear or damage, as well as check the fluid level and quality.
If any repairs are required, then additional fees may be added to the base price of the service.
How much does a rear end rebuild cost?
The cost of a rear end rebuild depends on the type and condition of the rear end, as well as the labor involved. The typical cost of a rear end rebuild can range from $500 to $1500, depending on the parts that need to be repaired or replaced.
Factors such as the make and model of the vehicle, the mileage, and the complexity of the work involved also affect the cost. If the rear end needs to be completely rebuilt or replaced, the cost could exceed $1500.
As an example, a complete rear end rebuild for a Jeep Wrangler with a set of 3. 73:1 gears costs about $2000.
How do you know your rear end is going out?
Most people can reasonably expect to get at least 150,000 miles out of their rear end without it needing repair or replacement. However, as with any mechanical component, wear and tear can cause it to fail before that point.
There are several indicators that your rear end is wearing out and might need to be serviced or replaced.
One common symptom is noises coming from the rear end. Grinding, clunking, or any other unusual sound is a strong indicator that something is wrong. This can be caused by worn or seized bearings, or possibly an issue with the pinion or ring and pinion.
If you start hearing any noise from the rear end, it is a good idea to bring the vehicle in for a diagnosis so the exact issue can be located and addressed.
Another warning signal that the rear end needs attention is vibration coming from the rear of the vehicle when accelerating or decelerating. This usually means that the pinion is out of line and the driveshaft is not rotating smoothly.
As with the noises, it should be checked out as soon as possible.
Finally, vibrations that can be felt through the steering wheel indicate an issue with the axle. This usually means either the axle bearings, U-joints, or the axle shafts themselves, are worn and need to be replaced.
If you suspect your rear end is going out, it is important to have it inspected by a professional as soon as possible to prevent further damage or a possible breakdown.
