Review BMW Rear Drive Shaft Driveshaft Propeller Oem fits F90 M5 2018–2021

The **BMW 8094726-02 Rear Drive Shaft (Propeller Shaft) for the 2018-2021 F90 M5** is a precision-engineered, high-performance drivetrain component designed to deliver uncompromising power and durability to BMW s legendary M5 sedan. This driveshaft is a critical link in the rear-wheel-drive system, transmitting the immense torque generated by the twin-turbocharged inline-six engine (N63B50) through the six-speed ZF Steptronic automatic transmission to the rear axle, ensuring seamless power delivery even under the most demanding driving conditions. Crafted from high-grade steel and reinforced with robust splines, this driveshaft is engineered to withstand the extreme forces exerted by the M5 s aggressive performance tuning, including high-speed cruising, aggressive acceleration, and spirited cornering. The design incorporates a balanced, vibration-dampening construction to minimize drivetrain noise and harshness, contributing to the M5 s signature blend of refinement and raw power. Compatible exclusively with the F90 M5 chassis (2018-2021 models), this driveshaft is a direct-fit replacement for the original equipment part, ensuring an exact match in length, angle, and mounting points, including the universal joint at the transmission output and the constant velocity (CV) joint at the rear axle. Whether used for routine maintenance, performance upgrades, or restoration projects, this driveshaft exemplifies BMW s commitment to engineering excellence, providing the reliability and responsiveness expected from an M5. Its robust construction and precise tolerances make it an essential component for maintaining the integrity of the M5 s rear-wheel-drive system, ensuring that every shift of the paddle shifters translates into immediate, linear power to the wheels.

### **Pros and Cons of Buying a BMW F90 M5 (2018-2021) Rear Driveshaft (Part Number: 8094726-02)**

#### **Pros of purchasing a Driveshaft (8094726-02)**

1. **OEM Quality and Fitment** This is a genuine BMW part, meaning it is designed to match the exact specifications of your F90 M5, ensuring proper alignment, balance, and performance. Aftermarket parts may not fit as precisely, leading to potential drivability issues or premature wear.

2. **Reliability and Durability** BMW s manufacturing standards for driveshafts are high, especially for high-performance models like the M5. A new or refurbished OEM part will be built to withstand the stresses of aggressive driving, towing, and high torque output without failing prematurely.

3. **Warranty Coverage** If purchased from an authorized BMW dealer or a reputable aftermarket supplier with warranty support, you may receive a limited warranty (typically 12-24 months). This provides peace of mind against defects in materials or workmanship.

4. **Prevents Costly Damage** A failing driveshaft can cause severe damage to the transmission, differential, or CV joints if it snaps while driving. Replacing it proactively avoids expensive repairs down the line, especially in a high-performance vehicle where such failures can occur suddenly.

5. **Maintains Performance Integrity** The driveshaft is critical for power delivery. A worn or damaged driveshaft can lead to vibrations, clunks, or even loss of power. Replacing it ensures optimal drivetrain efficiency, which is crucial for the M5 s performance-oriented driving experience.

6. **Easier Installation (If New)** A new OEM part comes with all necessary hardware (bolts, seals, etc.), and BMW s documentation ensures a straightforward installation process. Used/refurbished parts may require additional sourcing of hardware or adjustments.

7. **Resale Value Protection** Keeping your M5 in top condition with genuine parts helps maintain its resale value. Potential buyers will appreciate that major components like the driveshaft have been properly serviced.

#### **Cons of purchasing a Driveshaft (8094726-02)**

1. **High Cost** OEM BMW parts are significantly more expensive than aftermarket alternatives. The driveshaft for an F90 M5 can cost **$800 $1,500 **, depending on whether it s new, refurbished, or sourced from a third-party supplier. This is a substantial investment, especially if the part is still in good condition but needs replacement due to wear.

2. **Labor Costs** Replacing a driveshaft requires specialized tools, lifting equipment, and mechanical expertise. Labor costs for an M5 driveshaft replacement typically range from **$300 $600 **, depending on the shop and location. This can double or triple the total cost of the part itself.

3. **Potential for Counterfeit Parts** If purchasing from an untrusted source (e.g., eBay, Craigslist, or unscrupulous online marketplaces), there is a risk of receiving a **counterfeit or salvaged part**. These may not meet BMW s standards, leading to premature failure or poor performance. Always verify the part s authenticity (e.g., via BMW s part number database or a trusted dealer).

4. **Misdiagnosis of Symptoms** Driveshaft issues can sometimes be confused with other problems (e.g., worn CV joints, transmission issues, or suspension wear). If the original problem isn t correctly identified, you may end up replacing the driveshaft unnecessarily or missing another underlying issue.

5. **Time Off the Road** The replacement process takes **2 4 hours**, depending on the mechanic s experience. This means your M5 will be out of commission for at least a day, which can be inconvenient for daily drivers.

6. **Environmental and Ethical Concerns** If opting for a used/refurbished part, there may be ethical concerns about sourcing (e.g., salvaged from an accident). Some buyers prefer new parts for peace of mind, even if they are more expensive.

7. **Potential for Overkill** If the driveshaft is only lightly worn (e.g., minor cracks or surface rust), some mechanics may argue that it doesn t *need* immediate replacement. In such cases, monitoring it closely or opting for a less expensive aftermarket part might be justified.

### **Conclusion**

The decision to purchase the **BMW F90 M5 rear driveshaft (8094726-02)** depends on your vehicle s condition, budget, and long-term goals. Here s a balanced assessment:

- Your driveshaft shows **visible cracks, excessive rust, or play** (indicating imminent failure).

- You want **peace of mind** and are willing to invest in **OEM reliability** for a high-performance vehicle.

- You re **preventing a catastrophic failure** that could damage other drivetrain components.

- You re **selling or trading the car soon** and want to ensure a smooth transition for the next owner.

- The driveshaft is **only slightly worn** (e.g., minor surface rust or minor cracking). In this case, **monitor it closely** or consider an **aftermarket high-quality replacement** (e.g., from **Motive Parts, Jegs, or a trusted BMW specialist**).

- You re on a **tight budget** and can t afford the part labor. Prioritize other maintenance needs first.

- The **symptoms could be caused by something else** (e.g., CV joints, axle issues). Get a **professional inspection** before committing to replacement.

- **Aftermarket Driveshafts:** Brands like **Motive Parts, Jegs, or Apexi** offer high-quality, BMW-compatible driveshafts at a lower cost (often **$300 $600**). These can be a good compromise if you trust the brand s reputation.

- **Refurbished OEM Parts:** Some suppliers (e.g., **BMW Parts USA, RockAuto**) sell **rebuilt driveshafts** at a discount. Ensure they come with a warranty.

- **DIY Replacement:** If you have **mechanical experience**, you could save on labor by installing it yourself (though this requires proper tools and patience).

### **Final Recommendation**

1. **Get a professional inspection** to confirm the driveshaft is the root cause of symptoms (e.g., clunks, vibrations, or a "whining" noise).

2. **If replacement is necessary, prioritize an OEM part (8094726-02) from an authorized BMW dealer or a trusted third-party supplier** (e.g., **BMW Parts USA, RockAuto, or a local BMW specialist**) to avoid counterfeits.

3. **If budget is a concern, compare aftermarket options** (e.g., **Motive Parts or Jegs**) for a balance between cost and reliability. Ensure the part is **BMW-compatible and has good reviews**.

4. **Budget for labor** this is a **non-negotiable** part of the cost, and cutting corners here could lead to improper installation and future issues.

5. **If the driveshaft is only lightly damaged, consider delaying replacement** and monitoring it while addressing other higher-priority maintenance needs.

The **F90 M5 driveshaft is a critical component**, and replacing it with an **OEM or high-quality aftermarket part is the safest long-term solution** if it s failing. However, **weigh the cost against the urgency** if the part is still functional but showing signs of wear, a more conservative approach may be justified. Always **prioritize quality over cost** in a performance vehicle like the M5, as drivetrain failures can be dangerous and expensive.
