Mercedes-Benz R-Class W251 – Front Engine Mount Set (x2)
This listing covers a complete front engine mount replacement set for the Mercedes-Benz R-Class W251 chassis equipped with the 3.0L V6 diesel engine. The set comprises two rubber-metal dampening mounts, each replacing OEM part number A2512404117.
This mount is non-directional for this application — the same part fits both the left and right front positions. It secures the engine to the subframe while isolating drivetrain vibration from the cabin and maintaining correct powertrain alignment under braking and acceleration forces.
When to Replace
- Engine vibration felt through the floor or steering column
- Clunking or knocking from the engine bay during acceleration or at idle
- Engine rock during gear changes or hard braking
- Engine sitting at a visibly uneven angle
- Increased engine noise entering the cabin
Why Replace as a Pair
Both mounts accumulate identical mileage, heat cycles, and load stress. Replacing only one side places unequal load on the fresh mount and compromises engine alignment. A matched set restores correct geometry and even load distribution across the subframe.
