Review RAM Genuine Used Rear Drive Shaft Oem 5.7l fits 2500 4X4 2013–2018

The **RAM 3500/4500/5500 2013 2018 2500 5.7L V8 Rear Drive Shaft (Part # 68305646AC)** is a precision-engineered, high-performance drivetrain component designed exclusively for the iconic **Chrysler RAM 2500 Heavy-Duty 4x4** trucks equipped with the legendary **5.7L Magnum V8** engine. This rear drive shaft is a critical link in the vehicle s **part-time four-wheel-drive system**, ensuring seamless power transfer from the transfer case to the rear axle while maintaining optimal alignment, balance, and durability under the most demanding conditions. Built to exacting specifications, this drive shaft features a **heavy-duty tubular construction** reinforced with **high-strength steel**, capable of withstanding the immense torque and stress generated by the robust 5.7L V8 especially during towing, hauling, or off-road adventures. The shaft incorporates a **precision-machined universal joint (U-joint) at both ends**, allowing for smooth articulation and flexibility as the suspension moves, while the **constant velocity (CV) joint at the transfer case end** minimizes vibration and wear, even during aggressive driving maneuvers. Engineered to fit seamlessly within the **RAM 2500 s 4x4 drivetrain architecture**, this drive shaft is compatible with the **Tremec 6064 transfer case** and the **spider axle** configuration, ensuring a perfect match for the truck s rear-wheel-drive setup. Whether you re navigating rough terrain, conquering steep inclines, or simply relying on the truck for heavy-duty work, this drive shaft delivers **uncompromising strength, reliability, and longevity**, reducing the risk of catastrophic failure and ensuring a smooth, vibration-free ride. For those seeking **OEM-level performance and durability**, this RAM-specific drive shaft is an essential upgrade or replacement part, designed to restore factory integrity and extend the lifespan of your truck s drivetrain.

### **Pros and Cons of Buying a RAM 2500 Rear Drive Shaft (4x4, 5.7L, 2013-2018, Part # 68305646AC)**

1. **Compatibility** This is a direct-fit replacement for the rear drive shaft on the 2013-2018 RAM 2500 with a 5.7L HEMI V8 and 4x4 drivetrain. It ensures proper alignment and function without modifications.

2. **Durability** RAM trucks are built for heavy-duty use, and the drive shaft is designed to handle towing, hauling, and off-road conditions when properly maintained.

3. **Performance** A well-functioning drive shaft ensures smooth power transfer from the transmission to the rear axle, improving acceleration and towing capability.

4. **Reliability** If the original shaft was failing (e.g., due to rust, cracks, or worn u-joints), replacing it prevents drivetrain damage and avoids costly repairs down the line.

5. **Aftermarket Availability** This part is widely available from RAM dealers, OEM suppliers, and reputable aftermarket brands, making it easy to source.

6. **Cost-Effective Fix** Replacing a broken drive shaft is far cheaper than repairing transmission or axle damage caused by a failing shaft.

7. **Improved Safety** A properly functioning drive shaft reduces vibration and noise, enhancing driving comfort and preventing sudden drivetrain failures.

1. **Labor Intensity** Replacing a rear drive shaft requires lifting the truck, removing the exhaust, and disconnecting components, which can be time-consuming and may require professional help.

2. **Potential Hidden Damage** If the truck has been driven with a failing shaft, other drivetrain parts (e.g., yokes, u-joints, or axles) may be worn and need replacement.

3. **Cost of Installation** While the part itself is reasonably priced, labor costs at a shop can add up, especially if additional repairs are needed.

4. **Rust and Wear Risks** Older trucks (especially those driven in harsh conditions) may have rusted mounts or worn-out bushings, requiring extra maintenance.

5. **Misalignment Issues** If not installed correctly, the new shaft could cause vibration, clunking noises, or premature wear on other components.

6. **Limited Longevity Without Maintenance** Even a new shaft will degrade over time if not properly lubricated (u-joints) or if the truck is frequently towed at high loads.

7. **Potential for Counterfeit Parts** Cheaper aftermarket parts may not meet OEM standards, leading to premature failure or poor performance.

---

Replacing the rear drive shaft on a 2013-2018 RAM 2500 (5.7L, 4x4) with part **68305646AC** is a **necessary repair** if the original shaft is damaged, rusted, or failing. The benefits such as restored drivetrain function, improved safety, and prevention of further damage far outweigh the drawbacks, provided the installation is done correctly. However, the process requires careful attention to detail, and if the truck has been abused, additional repairs may be needed.

---

1. **Verify the Issue** Confirm that the drive shaft is indeed the problem (listen for clunking, check for leaks, and inspect for visible damage).

2. **Choose Quality Parts** Opt for an **OEM or high-quality aftermarket** shaft (e.g., **MOPAR, Dura-Bilt, or Currie**) to ensure longevity.

3. **Professional Installation** If you lack mechanical experience, have a **trusted mechanic** perform the replacement to avoid misalignment or improper fitting.

4. **Inspect Related Components** While replacing the shaft, check **u-joints, yokes, mounts, and bushings** for wear and replace them if needed.

5. **Maintain Proper Lubrication** Regularly grease the u-joints to prevent premature failure.

6. **Consider a Full Drivetrain Check** If the truck has been driven with a bad shaft, inspect the **transfer case, axles, and differential** for damage.

7. **Budget for Additional Costs** Account for **labor, potential extra parts, and disposal fees** when planning the repair.

**Final Verdict:** **Worth the investment** if the shaft is failing, but prioritize **quality parts and professional installation** to maximize reliability. If the truck has extensive drivetrain wear, consider evaluating its overall condition before committing to the repair.
