Step-by-Step Installation Guide
Step 1: Prepare Your Jeep
Start by parking your Jeep on a flat surface and engaging the parking brake. Use a jack to lift the rear end of the vehicle and secure it with jack stands. Make sure the wheels are off the ground for easier access to the differential.
Step 2: Remove the Differential Cover
Using a socket set, remove the bolts securing the differential cover. Carefully pull the cover off, allowing the gear oil to drain into a pan. Clean the mating surface on the differential housing to prepare for the new cover.
Step 3: Remove the Old Differential
Remove the pinion shaft by taking out the retaining bolt. Then, remove the axle shafts by pulling them out of the housing. Finally, take out the existing differential by removing the bolts securing it in place.
Step 4: Install the Eaton TrueTrac LSD
Position the Eaton TrueTrac LSD in the differential housing. Secure it using the bolts you previously removed. Make sure to follow the manufacturer’s torque specifications for a secure fit.
Step 5: Reinstall the Axle Shafts
Carefully slide the axle shafts back into the housing, ensuring they are properly seated. Reinsert the pinion shaft and secure it with the retaining bolt.
Step 6: Replace the Differential Cover
Apply sealant to the differential cover’s mating surface. Position the cover back onto the differential housing and secure it with the bolts. Again, follow the manufacturer’s recommended torque specifications.
Step 7: Fill with Gear Oil
Fill the differential with the appropriate gear oil as specified in the TrueTrac installation manual. Make sure to check the oil level to ensure it is filled to the correct height.
Step 8: Lower Your Jeep
Carefully lower your Jeep back to the ground and remove the jack stands. Make sure everything is secure before taking it for a test drive.
Testing Your Installation
After installation, take your Jeep for a test drive to ensure the TrueTrac is functioning correctly. Pay attention to how the vehicle handles during turns and off-road conditions.
Conclusion
Installing an Eaton TrueTrac LSD in your Jeep Wrangler JK can dramatically improve traction and handling. By following these steps, you can achieve a successful installation and enjoy enhanced performance on and off the road.
