Reasons Behind Differential Failure in Your Mercedes

by techplusaadmin July 3, 2019

Mercedes are high-end vehicles that are reliable and well-built. They do come with issues, just like any car. A common issue Mercedes models have is with failure of the differential. Mercedes has made it a point to let the consumer know that their newer models have lifetime fluid in the differential, but this is misleading. In this article, let’s take a look at differential failure and where to go for help.

What is the differential?

The differential is an important part of your Mercedes. Its purpose is to transfer the power from your engine to the wheels. It also allows the wheels to rotate at different speeds. This is important in turns.

Over time, everyday wear and tear can lead to differential failure. The gears can wear down, and metal shavings can contaminate your gear oil and differential fluid. If the issue gets to this point, you are looking at an expensive service repair.

Symptoms of Differential Failure

Differential Oil Leak

All leaks are a concern, and it is important when you spot a leak that you have the issue diagnosed right away. If the leak is coming from the axles, there is a good chance that it is differential oil. Not fixing the problem can lead to wheel, axle, and transmission damage.

Loud Noises

If you begin to hear strange noises when you are turning the wheel, the differential is the likely culprit. You need to have this looked at right away to prevent complete failure. You may also experience an extremely bumpy ride, which is uncharacteristic for a Mercedes.

Whining Noises

The most common issue that people notice with a failing differential is a whining noise coming from the transmission or differential. This noise is caused by the lack of proper lubrication.

Burning Smells

Differential oil can thicken over time and burn. In turn, this can lead to failure of other components.

Service Engine Light is On

Your service engine light can be illuminated for a number of reasons. Your Mercedes is equipped to tell you when it is experiencing an issue. If this light is triggered, it is best that you have a trained technician perform a diagnostic scan to determine the exact cause of the problem.

Preventing Differential Failure

If your Mercedes experiences differential failure, it can lead to serious damage to other parts. Maintaining your differential can help you avoid failure as well as high service repair bills.

Check the Fluid

Even though Mercedes states that they have lifetime fluid in their differential, you still need to have it checked. The differential isn’t equipped with a filter, so metal shaving can easily enter. Eventually, this contamination will lead to damage. It is commonly recommended that you have the fluid changed every 60,000 miles to prevent this damage.

Don’t do Burnouts or Allow the Wheels to Spin

The excessive wheel speed combined with the sudden jolt from the wheel traction can lead to damage.

Inspect the Components Regularly

To help prevent future issues, perform frequent inspections to make sure that the components are all in good shape and free of corrosion.
