Review MERCEDES Engine Motor Support Mount Right Oem 80k fits W208 CLK430 CLK55 E430 1998–2003

The **Mercedes-Benz 1122233704 engine motor mount (right side) for the W208 CLK-Class (models CLK430, CLK55, and E430, produced between 1998 and 2003)** is a critical suspension component designed to securely isolate and support the engine assembly within the vehicle s chassis. This high-performance rubber-metal mount is engineered to absorb vibrations, reduce noise transmission, and maintain precise engine positioning, ensuring optimal drivetrain alignment and longevity. Crafted from durable, high-grade rubber reinforced with steel inserts, the mount is built to withstand the rigorous demands of the M113 E430 V8 engine, which powers the CLK55 and CLK430 variants, as well as the M111 E430 inline-six found in the base model. The right-side motor mount plays a pivotal role in maintaining the engine s lateral stability, preventing excessive movement during acceleration, braking, or cornering, which could lead to drivetrain misalignment, unusual engine noise, or even catastrophic failure in extreme cases.

This part is specifically designed to fit the **W208 body architecture**, a generation known for its sporty handling and luxury-oriented performance. The mount s robust construction helps mitigate the harsh vibrations generated by the powerful V8 engine in the CLK55, ensuring a smoother ride and reducing fatigue on the vehicle s suspension system. Over time, however, the rubber compound can degrade due to exposure to heat, oil, and road debris, leading to cracks, stiffness, or complete failure symptoms that often manifest as clunking noises, engine movement, or a noticeable loss of ride quality. Replacing this mount with the genuine **Mercedes-Benz 1122233704** ensures a perfect fit and restores the original factory specifications, preventing further damage to the engine mounts, suspension components, or even the engine itself.

Installation of this motor mount requires careful attention to detail, as improper alignment can lead to premature wear or failure. The part is designed to be compatible with the vehicle s existing mounting points, featuring precise bolt holes and a mounting bracket that securely attaches to the engine block or subframe. For optimal performance, it is recommended to replace both the right and left motor mounts simultaneously, as wear often occurs symmetrically. This component is a direct-fit replacement, eliminating the need for modifications, and is ideal for both professional mechanics and experienced DIY enthusiasts working on their W208 CLK-Class vehicles. Whether restoring a classic CLK to its original condition or addressing a failing suspension component, the **Mercedes-Benz 1122233704 engine motor mount (right)** is an essential part for maintaining the integrity and performance of this iconic luxury sports sedan.

### **Pros and Cons of Buying a Mercedes-Benz W208 CLK (1998-2003) Right Motor Mount (Part #1122233704, E430 Engine)**

1. **Direct Fitment** This part is specifically designed for the **E430 4.3L V8 engine** in the **CLK430, CLK55 (pre-facelift, 1998-2003)** models, ensuring compatibility without modifications.

2. **OEM Quality** Mercedes-Benz parts are built to high standards, providing durability and proper fit compared to aftermarket alternatives.

3. **Prevents Engine Damage** A failing motor mount can lead to excessive vibration, driveline angles, or even engine detachment. Replacing it early avoids costly repairs.

4. **Improves Ride Comfort** A worn mount can cause rattling, clunking noises, or uneven suspension behavior. A new mount restores smooth operation.

5. **Long-Term Reliability** The E430 is a robust engine, and replacing worn components like mounts helps maintain its longevity.

6. **Easier Installation** Since it s an OEM part, it should align correctly with minimal adjustments, reducing installation time and potential errors.

7. **Warranty Coverage** If purchased from an authorized dealer or reputable seller, the part may come with a warranty, offering peace of mind.

---

1. **High Cost** OEM Mercedes parts are expensive, often **$200 $400 ** depending on the source. Aftermarket alternatives may be cheaper but risk fitment or quality issues.

2. **Labor Intensive** Replacing a motor mount requires lifting the engine slightly, which may necessitate **removing the exhaust, subframe, or even the driveshaft**. This can add significant labor costs (typically **$300 $600 ** at a shop).

3. **Potential for Counterfeit Parts** Purchasing from untrusted sellers (e.g., eBay, Craigslist) risks receiving **fake or low-quality parts**, leading to premature failure.

4. **Additional Wear Indicators** If the mount is failing, other components (e.g., **subframe bushings, exhaust hangers, or engine mounts**) may also be worn and should be inspected/replaced simultaneously.

5. **Limited Availability** Some sellers may not stock this exact part, requiring special ordering, which can delay repairs.

6. **Skill Dependency** If attempting a DIY replacement, improper installation (e.g., incorrect torque, misalignment) can cause **engine vibration, driveline issues, or even damage to the transmission or subframe**.

7. **Age of the Vehicle** The **W208 CLK (1998-2003)** is an older model with **common issues** (e.g., water pump failures, timing chain wear, electrical gremlins). Addressing the motor mount may just be the beginning of a larger repair project.

### **Conclusion**

Buying the **Mercedes-Benz W208 CLK (1998-03) Right Motor Mount (1122233704, E430 engine)** is a **necessary and wise investment** if the part is failing, as it prevents **catastrophic engine damage** and maintains drivability. However, the **high cost and labor requirements** make it a significant expense, especially for an older vehicle.

If the **CLK is otherwise in good condition**, replacing the mount is a **practical step** to avoid future problems. If the car has **multiple major issues**, the repair may not be justified unless you plan to **keep it long-term**.

---

### **Recommendation**

1. **Verify the Need** Confirm the mount is indeed failing (listen for **clunks, rattles, or excessive vibration**). Have a mechanic inspect it before purchasing.

2. **Source the Part Carefully**

- Buy from **authorized Mercedes dealers, reputable online retailers (e.g., RockAuto, PartsGeek), or trusted salvage yards**.

- Avoid **eBay or unknown sellers** unless you can verify authenticity.

3. **Budget for Labor** If not DIYing, factor in **$300 $600 ** for professional installation.

- **Subframe bushings**

- **Exhaust hangers**

- **Transmission mounts**

- **Water pump & timing chain** (common failures in E430s)

5. **Consider Aftermarket Alternatives** If budget is tight, **Fel-Pro, Eurospec, or Mann Filter** offer **high-quality, lower-cost** options (though fitment should be confirmed).

6. **DIY vs. Shop Decision**

- If comfortable with **mechanical work**, DIY installation is possible but **time-consuming**.

- If unsure, **hire a specialist** (preferably one familiar with Mercedes engines).

7. **Long-Term Viability** If the CLK has **high mileage or other major issues**, weigh whether the repair is worth it. If the car is a **project vehicle**, the mount replacement is still justified.

**Proceed with the purchase if the mount is confirmed faulty and the vehicle is otherwise reliable.** The E430 is a **strong engine**, and maintaining its supporting components ensures **safety and longevity**. However, be prepared for **higher costs** and consider **additional inspections** to avoid future repairs.
