Frequently Asked Questions

Is there a specific left and right mount?
No. For the applications listed under this part number (A2212400817), the engine mounts are symmetrical. This means the same part number is used for both the driver and passenger sides. This kit provides the two identical mounts required for a full front-axle replacement.
Why should I replace both at the same time?
Highly Recommended. Engine mounts age and wear at the exact same rate. If one mount has collapsed and leaked its fluid, the other has likely been under increased stress and is near failure. Replacing them as a pair ensures the engine sits level and prevents you from paying for the same labor twice.
Does this set fit 4MATIC (All-Wheel Drive) models?
Yes. This specific part number is the primary engine mount for many 4MATIC versions of the C-Class (W204) and S-Class (W221). However, always verify your VIN as some 4MATIC subframes have very specific clearance requirements.
Will this fix my vibration at idle?
Yes. If your engine is mechanically sound (no misfires or vacuum leaks) but you feel a "thrumming" vibration through the car when stopped in gear, collapsed hydraulic mounts are almost always the culprit.
