Mercedes Steering Wheel Vibration

Modesto’s Premier Repair Shop to Tackle a Mercedes Differential Failure

A differential is a mechanical system located in the axle of your Mercedes, and its primary function is to split the power generated by the engine between the wheels on an axle while allowing them to rotate at different speeds. This is important to maintain smooth and stable handling when you are making a turn.

The differential receives power from the vehicle’s transmission or driveshaft. This power is then transferred to the differential’s input shaft. Within the differential, you’ll find a set of gears, usually referred to as the ring and pinion gears. The input shaft is connected to the pinion gear, while the ring gear is connected to the differential case. The pinion gear meshes with the ring gear, transferring power to it. The differential has two output shafts, one for each wheel on the axle. These shafts are connected to the side gears inside the differential.

The side gears are attached to the axle shafts. When power is transferred from the ring gear to the side gears, it is further transmitted to the axle shafts. During a turn, the inner wheel travels a shorter distance than the outer wheel. This differentiation in wheel speed is what enables your Mercedes to turn smoothly and without skidding.

Why Does Your Mercedes Differential Fail?


Overloading your Mercedes with excessive weight, especially if done repeatedly, can put unnecessary strain on the differential. The differential’s job is to distribute power to the wheels effectively, and excessive weight places extra stress on this component. Over time, this added stress can cause the differential to wear out and potentially fail.

Aggressive Driving

Hard acceleration, abrupt stops, and aggressive cornering can put immense pressure on the differential. This kind of driving behavior places a significant load on the differential’s gears and bearings, leading to accelerated wear and potential failure. It’s essential to drive your Mercedes with care and avoid unnecessary strain on the drivetrain.

Lack of Maintenance

Regular maintenance is vital for the longevity and performance of your Mercedes. Neglecting to change the differential oil, which serves as a lubricant for the gears and bearings inside the differential, can lead to accelerated wear and eventual failure.

How to Identify Mercedes Differential Failure

Unusual Noises

One of the most common and easily recognizable signs of differential issues is the presence of strange noises. These can include whining, clunking, or grinding sounds coming from the rear or front of your Mercedes. These noises are particularly noticeable during turns. Whining noises may indicate worn gears or a lack of lubrication while clunking sounds could signify more severe damage.


If you experience vibrations, especially during acceleration or at specific speeds, it could be a sign of differential problems. These vibrations can be felt through the steering wheel or the entire vehicle, and they are often associated with imbalances or issues within the differential.

Handling Issues

Differential problems can have a noticeable impact on your car’s handling. You may find that your Mercedes doesn’t respond as smoothly to turns, or you might experience understeer (the vehicle doesn’t turn as sharply as intended) or oversteer (the rear of the car slides out during turns) during cornering. These handling issues can compromise the safety and control of your Mercedes.
