What Is Rear Differential Service, and How Do I Know If I Need It?

There are many different maintenance tasks that are necessary to keep your vehicle running efficiently. For some vehicles, these tasks can include rear differential service. North Penn Volkswagen is highlighting what this service is and how to know if you need it.

What Is a Rear Differential?

Your rear differential is the part of your vehicle that helps your rear wheels rotate at different speeds. It can distribute your engine’s power to each wheel independently, helping improve your handling and traction, so it’s especially important when turning or cornering. A rear differential isn’t found on a vehicle with front-wheel drive, though – only rear-wheel drive and all-wheel drive vehicles are equipped.

What Is Rear Differential Service?

To keep your rear differential functioning efficiently, it needs to be routinely serviced. Rear differential service includes removing the old and inefficient fluid in your vehicle and replacing it with new fluid. It also includes an inspection of the system to look for any unusual or excessive wear.

How Often Do I Need Service?

As a general rule of thumb, you should complete rear differential service every 30,000 to 60,000 miles. However, if you have harsh driving conditions or do a lot of towing or hauling, you may need to schedule service more frequently. Your owner’s manual will detail your specific guidelines.

Signs You Need Rear Differential Service

If you have a rear differential, it needs to be serviced regularly. You should schedule service outside your normal interval if you notice any warning signs such as:

• Grinding or clunking noises
• Difficulty turning
• Unusual vibrations
• Fluid leak
• Unusual or uneven tire wear
