The **Mercedes-Benz 2104103016 (4722EM) Rear Driveshaft for the W210 E320 (1998 2003)** is a precision-engineered, high-performance propeller shaft designed exclusively for the iconic W210 generation of the E-Class sedan and wagon. This driveshaft is a critical component of the vehicle s rear-wheel-drive system, ensuring seamless power transfer from the transmission to the rear axle while maintaining optimal balance, durability, and reliability under demanding driving conditions. Manufactured to Mercedes-Benz s exact specifications, this driveshaft features a robust **4722EM part number**, which corresponds to the original equipment (OEM) design used in the factory assembly of the E320 models produced between 1998 and 2003. Constructed from high-strength steel, it incorporates a **slip-yoke joint** at the transmission end and a **constant velocity (CV) joint** at the axle end, allowing for smooth articulation and flexibility as the suspension moves, even during aggressive cornering or off-road maneuvers. The driveshaft is dynamically balanced to minimize vibration, contributing to a refined and comfortable ride while maintaining the E320 s signature blend of luxury and performance. Whether installed in a meticulously restored classic or a daily-driven luxury sedan, this driveshaft guarantees the same level of precision and reliability that Mercedes-Benz drivers expect, ensuring that every drive is both powerful and effortless. Its compatibility with the W210 s rear-wheel-drive architecture makes it an essential replacement for vehicles experiencing wear, damage, or failure in the original driveshaft, helping to preserve the integrity of the drivetrain and extend the lifespan of the vehicle.
### **Pros and Cons of Buying a Mercedes-Benz W210 E320 Rear Driveshaft (Part Number: 2104103016, 1998 2003)**
#### **Pros:**1. **OEM Quality and Reliability** This is a genuine Mercedes-Benz part, meaning it meets the manufacturer s high standards for durability and performance. Unlike aftermarket knockoffs, it is designed to integrate seamlessly with the vehicle s drivetrain.
2. **Long-Term Durability** The W210 E320 was built with robust engineering, and the driveshaft is no exception. With proper maintenance, this part can last the lifetime of the vehicle, reducing the risk of premature failure.
3. **Easy Availability** As an older but still widely produced model, replacement parts like this driveshaft are relatively easy to source from authorized dealers, junkyards, or reputable online suppliers. This ensures you won t face long wait times for critical repairs.
4. **Compatibility with Aftermarket Upgrades** Since the W210 platform is well-documented, many aftermarket tuners and mechanics have experience working with its components. This makes modifications (such as suspension upgrades or performance tuning) easier to execute.
5. **Resale Value Potential** If you plan to sell the car later, maintaining it with genuine parts like this driveshaft can help preserve its value, especially if you keep records of all service work.
6. **Reduced Risk of Voiding Warranty** If you re working on a newer or still-warranted vehicle, using an OEM part ensures that warranty claims won t be denied due to non-genuine replacements.
7. **Better Fit and Function** Unlike aftermarket parts that may require additional machining or adjustments, this driveshaft is designed to fit perfectly, reducing the chance of misalignment or premature wear.

#### **Cons:**1. **Higher Cost Compared to Aftermarket Alternatives** Genuine Mercedes-Benz parts are significantly more expensive than aftermarket equivalents. While the price reflects quality, it may not be cost-effective for budget-conscious buyers or those who prioritize immediate savings over long-term reliability.
2. **Potential for Counterfeit Parts** Even with an OEM part number, there is a risk of purchasing a counterfeit or refurbished part that hasn t been properly inspected. Buying from untrusted sellers (e.g., unlicensed online marketplaces) could result in a substandard or damaged driveshaft.
3. **Limited Longevity in Harsh Conditions** While the driveshaft itself is durable, exposure to extreme temperatures, salt corrosion (in winter climates), or rough driving conditions can accelerate wear. Regular inspections are necessary to prevent failure.
4. **Installation Complexity** Replacing a driveshaft on a W210 requires mechanical skill, proper tools, and sometimes specialized equipment (e.g., a torque wrench for precise bolt tightening). DIYers without experience may struggle, leading to potential mistakes or improper alignment.
5. **Age-Related Wear in the Vehicle Itself** If the car is older (especially nearing 25 years), other components (e.g., differential, CV joints, or mounts) may also be worn. Replacing just the driveshaft without addressing these issues could lead to recurring problems.
6. **Environmental and Ethical Concerns** Purchasing a new OEM part contributes to automotive waste. If you re environmentally conscious, you might consider a remanufactured or recycled part instead, though these may not always be as reliable.
7. **Potential for Overkill** If the driveshaft is failing due to a minor issue (e.g., a loose joint or minor corrosion), replacing it entirely may be excessive. In such cases, a targeted repair (e.g., sealing a leak) could be more economical.

### **Conclusion**
Buying a genuine Mercedes-Benz W210 E320 rear driveshaft (2104103016) is a **highly recommended choice** if you prioritize reliability, longevity, and seamless integration with your vehicle. The part s OEM status ensures it will perform as intended, reducing the risk of drivetrain issues and maintaining the car s integrity. However, the higher cost and potential for counterfeit parts mean you should verify the seller s reputation and consider whether the expense aligns with your budget and needs.
For most serious Mercedes owners especially those who value the brand s engineering this is the **best option**. If cost is a major concern, a **high-quality aftermarket part from a trusted supplier** (e.g., Mann, Febi, or a reputable remanufacturer) could be a viable alternative, provided it meets Mercedes specifications and comes with a warranty.
### **Recommendation:**- **If you can afford it and want peace of mind**, purchase the **genuine Mercedes-Benz part** from an authorized dealer or a well-reviewed online retailer (e.g., RockAuto, eBay with verified sellers, or a local Mercedes specialist).
- **If budget is tight**, research **aftermarket brands** with strong reviews (e.g., Mann Filter, Febi Bilstein, or Dorman) and ensure they offer a warranty. Check for compatibility with your specific model year.
- **Always inspect the part** upon receipt for damage, corrosion, or signs of wear before installation.
- **Consider professional installation** if you lack mechanical experience, as improper fitting can lead to drivetrain damage.
- **Pair the replacement with a full drivetrain inspection** to address any underlying issues (e.g., worn CV joints, differential leaks) that could affect the driveshaft s performance.
Ultimately, the **genuine part is the safest choice** for long-term reliability, while aftermarket options can be a cost-effective alternative if thoroughly vetted.
