This article tackles the common issue of a failing driveshaft center support bearing in a 2016 Dodge Charger. We’ll explore the crucial decision of whether to repair or replace the entire driveshaft, providing a step-by-step breakdown of the replacement process, along with unique insights gained from real-world experience. We will also address how to diagnosis a failing bearing, and what to do when faced with repair challenges.
The driveshaft center support bearing is a critical component in your 2016 Dodge Charger’s drivetrain. It’s designed to support the driveshaft and reduce vibrations, ensuring smooth power transfer from the transmission to the rear differential. When this bearing fails, it can lead to a range of noticeable symptoms.
Common indicators of a failing center support bearing include: vibrations felt through the floorboard, a rumbling or grinding noise, especially at higher speeds, and a clunking sound when shifting gears. Ignoring these symptoms can lead to further damage to the driveshaft, transmission, or differential, resulting in more costly repairs down the road.
Repair or Replace: Making the Right Choice
When faced with a faulty center support bearing, you have two primary options: replace the bearing itself or replace the entire driveshaft assembly. There’s no single “right” answer, as the best course of action depends on several factors.
Replacing just the bearing can be a more cost-effective solution if the driveshaft itself is in good condition. However, this approach requires specialized tools and skills, as pressing the old bearing off and the new one on can be challenging. Furthermore, if the driveshaft has any signs of wear, such as damaged splines or a bent shaft, replacing the entire assembly is highly recommended.
Replacing the entire driveshaft assembly is often the more straightforward and reliable option, especially for DIYers. While it’s more expensive upfront, it ensures that all components are new and properly balanced, minimizing the risk of future issues. Additionally, many aftermarket driveshafts offer improved performance and durability compared to the factory unit.
2016 Dodge Charger Driveshaft Center Bearing Replacement: A Step-by-Step Overview
Note: This is a general overview. Always consult your 2016 Dodge Charger’s service manual for specific instructions and torque specifications.
- Preparation: Gather necessary tools, including a socket set, wrenches, penetrating oil, a torque wrench, jack stands, and wheel chocks. Disconnect the negative battery cable for safety.
- Vehicle Lifting and Securing: Safely raise the vehicle using a jack and secure it with jack stands. Ensure the vehicle is stable before proceeding.
- Driveshaft Disconnection: Locate the driveshaft and mark its position relative to the differential and transmission flanges. This ensures proper alignment during reinstallation. Loosen and remove the bolts connecting the driveshaft to these flanges.
- Driveshaft Removal: Carefully slide the driveshaft out of the transmission and lower it from the vehicle. Be mindful of any fluid spillage.
- Center Support Bearing Replacement (If applicable): If replacing only the bearing, use a press to remove the old bearing from the driveshaft and install the new one. Ensure the bearing is properly aligned and seated. This step is often the most challenging and requires specialized equipment.
- Driveshaft Installation: Align the driveshaft with the markings made during removal and carefully slide it back into position.
- Fastening: Secure the driveshaft to the transmission and differential flanges using the appropriate bolts. Torque the bolts to the manufacturer’s specified torque.
- Finalization: Double-check all connections and ensure the driveshaft is properly aligned. Lower the vehicle and reconnect the negative battery cable. Test drive the vehicle to verify proper operation.
Important Safety Note: Always wear safety glasses and gloves when working under a vehicle. If you’re not comfortable performing this repair yourself, consult a qualified mechanic.
Unique Insights and Lessons Learned from Replacing a 2016 Charger Driveshaft
From personal experience, I’ve learned a few tricks that aren’t always covered in the service manual.
- Penetrating Oil is Your Best Friend: Before attempting to remove any bolts, soak them thoroughly with penetrating oil. This will help prevent them from snapping or stripping, saving you a lot of headaches.
- Marking is Key: Don’t just mark the driveshaft’s position relative to the flanges; also mark the orientation of the driveshaft halves (if applicable). This ensures proper balancing and minimizes vibrations.
- Don’t Cheap Out on the Bearing (or Driveshaft): I once tried to save money by buying a cheap aftermarket center support bearing. It failed within a few months, forcing me to redo the entire job. Investing in a quality bearing or a reputable driveshaft assembly is worth the extra cost in the long run.
- Consider heat: Applying a small amount of heat to the bearing support can allow it to expand and become easier to remove.
- Grease is the word: Be sure to pack the new bearing with a quality, high temp grease.
Avoiding Common Pitfalls
One of the biggest mistakes people make is over-tightening the bolts. Always use a torque wrench and adhere to the manufacturer’s specified torque. Over-tightening can damage the flanges or strip the threads, leading to further complications.
Another common mistake is failing to properly align the driveshaft. If the driveshaft is not aligned correctly, it can cause vibrations and premature wear on the center support bearing and other drivetrain components.
