Review FORD TRUCK Rear Drive Shaft Cab 6ft Inch Box Pickup fits CREW F250SD 2WD 2017–2020

The **Ford 431-06393 Rear Drive Shaft (Crew Cab, 6-Foot Box, 2WD, 2017-2020 F-250 Super Duty)** is a precision-engineered, high-performance drivetrain component designed exclusively for Ford s full-size Super Duty lineup, ensuring seamless power delivery and durability for demanding towing, hauling, and off-road applications. This **original equipment (OEM) replacement drive shaft** is meticulously crafted to match the exact specifications of the factory unit, featuring a robust **6-foot length** optimized for the Crew Cab configuration with a standard cab and extended cab box, providing the ideal balance between clearance and drivetrain efficiency. Constructed from **high-strength steel**, the shaft is reinforced with **heavy-duty universal joints (U-joints)** and **constant velocity (CV) joints** at both ends, delivering smooth, vibration-free power transfer while withstanding the rigors of heavy-duty use, frequent towing loads, and rough terrain. The **sleeve design** ensures proper alignment and reduces wear, while the **sealed, grease-filled joints** protect internal components from dust, debris, and moisture, extending the shaft s lifespan under extreme conditions. Engineered for **2-wheel drive (2WD) applications** on the **F-250 Super Duty (SD) with a crew cab**, this drive shaft is compatible with **3.5L EcoBoost, 6.0L Power Stroke, and 7.3L Power Stroke engines**, making it a versatile upgrade or replacement for vehicles requiring reliable, off-road-capable performance. Whether used in construction, agriculture, or heavy-duty transport, this drive shaft ensures **consistent torque transfer**, minimal noise, and long-term reliability, reinforcing the F-250 s reputation as a workhorse capable of handling the toughest jobs with ease.

**Pros and Cons of buying a Ford 431-06393 Rear Drive Shaft (Crew Cab, 6-Foot Box, 2WD, 2017-2020 F-250 Super Duty)**

### **Pros**

1. **Direct OEM Replacement** This is a genuine Ford part, ensuring a perfect fit for your 2017-2020 F-250 Super Duty with a crew cab and 6-foot box. It will integrate seamlessly with your vehicle s drivetrain without modifications.

2. **High-Quality Materials** Ford uses durable components in its drive shafts, including balanced shafts and robust joints, which reduces vibration and wear over time. This helps prevent premature failure, especially in heavy-duty applications.

3. **Warranty Coverage** Purchasing from an authorized Ford dealer or a reputable aftermarket supplier often includes a warranty (typically 12-60 months, depending on the seller). This provides peace of mind against defects or early failure.

4. **Improved Durability** The 2WD rear drive shaft is designed for the demands of towing and hauling. A new or high-quality aftermarket shaft will outlast a worn-out original, reducing the risk of in-transit failures that could damage your vehicle or cargo.

5. **Compatibility with Upgrades** If you plan to modify your F-250 (e.g., lift kit, heavier payloads, or performance tuning), a fresh drive shaft ensures it can handle increased stress without compromising safety.

6. **Easier Maintenance** A new shaft simplifies future inspections. You won t have to worry about cracked yokes, worn-out u-joints, or misalignment issues that can arise with high-mileage original parts.

7. **Resale Value Protection** Keeping your truck in top condition with OEM or high-quality aftermarket parts helps maintain its resale value, especially if you plan to sell it in the future.

8. **Reduced Noise and Vibration** A balanced, properly installed drive shaft minimizes road noise and vibrations, improving ride comfort particularly noticeable in long-haul or off-road driving.

9. **Prevents Costly Repairs** A failing drive shaft can lead to catastrophic failure (e.g., shaft separation mid-drive), which can damage the transfer case, axle, or even the vehicle itself. Replacing it proactively avoids emergency repairs.

10. **Professional Installation Option** Many dealerships and shops offer installation services, ensuring proper alignment and torque specifications are met, which extends the shaft s lifespan.

### **Cons**

1. **High Upfront Cost** Genuine Ford drive shafts are expensive, often ranging between **$800 and $1,500 **, depending on the seller and whether installation is included. Aftermarket options may be slightly cheaper but could lack warranty coverage or durability.

2. **Labor Costs if DIY Isn t an Option** If you re not comfortable with mechanical work, professional installation can add **$150 $300** to the total cost, depending on the shop s rates.

3. **Potential for Counterfeit Parts** Buying from untrusted sellers (e.g., eBay, Craigslist, or unverified online marketplaces) risks receiving a knockoff part that fails prematurely. Always verify the seller s authenticity.

4. **Time-Consuming Installation** Removing and reinstalling the drive shaft requires disconnecting the axle, transfer case, and other components. This can take **2 4 hours** for a DIYer, depending on experience.

5. **Weight Consideration** While not significant, the drive shaft adds to the truck s overall weight. In fuel-efficient driving, this may slightly reduce MPG, though the impact is minimal for most applications.

6. **Limited Lifespan in Extreme Conditions** Even a new shaft may wear faster in severe off-road use, extreme towing loads, or harsh climates (e.g., salt corrosion in winter). Regular inspections are still necessary.

7. **Misalignment Risks if Not Installed Properly** Incorrect alignment or torque can lead to premature wear or failure. This underscores the importance of following Ford s specifications or using a professional installer.

8. **Part Availability Delays** If ordering from a dealer, stock may not always be available immediately, leading to wait times. Aftermarket suppliers may offer faster turnaround but with varying quality.

9. **Potential for Overkill** If your truck has low miles and the original shaft is still functional, replacing it may not be justified unless you re planning heavy-duty use or notice symptoms of wear (e.g., clunks, vibrations, or grease leaks).

10. **Environmental Impact** Like any mechanical replacement, disposing of the old shaft requires proper recycling or disposal, which may not be convenient for all buyers.

### **Conclusion**

Replacing the rear drive shaft on your **2017-2020 F-250 Super Duty (2WD, crew cab, 6-foot box)** is a **highly recommended preventive maintenance measure** if you:

- Notice **vibrations, clunks, or grease leaks** in the shaft.

- Plan to **tow heavy loads, haul frequently, or modify the truck**.

- Want to **avoid unexpected failures** that could lead to costly repairs or safety risks.

- Are **selling the truck soon** and want to ensure it s in optimal condition.

The **pros far outweigh the cons** for most owners, especially those who prioritize reliability and longevity. The **cost is justified** by the potential for avoiding a **$1,500 repair** if the shaft fails mid-drive.

However, if your truck is **low-mileage (under 50,000 miles) and the original shaft shows no signs of wear**, the replacement may not be urgent. In that case, **monitor it closely** and replace only when necessary.

---

### **Recommendation**

1. **Buy from a Trusted Source** Purchase the **Ford 431-06393** from an **authorized Ford dealer, reputable aftermarket supplier (e.g., RockAuto, Jegs, or local Ford parts stores), or a verified online retailer**. Avoid untested sellers to ensure authenticity.

2. **Consider Aftermarket Alternatives** If budget is a concern, high-quality aftermarket brands like **Dana, Spicer, or Currie** offer competitive options with warranties. Compare specs to ensure compatibility.

3. **Plan for Professional Installation** Unless you re experienced with heavy-duty repairs, **have a mechanic install it** to guarantee proper alignment and torque. This adds cost but prevents future issues.

4. **Inspect the Old Shaft** Before buying, check the **u-joints, yokes, and grease fittings** on your current shaft. If they re **cracked, corroded, or dry**, replacement is critical.

5. **Budget for Accessories** Consider purchasing **new u-joint grease and a torque wrench** to ensure long-term performance.

6. **Set a Reminder for Future Checks** Even with a new shaft, **inspect it every 12 18 months**, especially if you tow heavily or drive off-road.

**Final Verdict:** **Replace the drive shaft if it s worn or you re preparing for heavy use.** The investment in reliability and safety is well worth it for the **F-250 s demanding applications**. If unsure, consult a **Ford-certified technician** to assess the condition of your current shaft before deciding.
