Installing an aftermarket differential on your Dodge Demon can significantly improve its performance and handling. This guide provides step-by-step instructions to help you complete the installation safely and effectively.
Tools and Materials Needed
- Socket set and wrenches
- Jack and jack stands
- Drain pan
- Gear oil
- New differential
- Gasket and sealant
- Torque wrench
- Brake cleaner
- Rubber mallet
Preparation
Before starting, ensure your vehicle is parked on a level surface. Engage the parking brake and disconnect the negative battery terminal. Lift the rear of the vehicle using a jack and secure it with jack stands. Carefully remove the rear wheels for better access.
Removing the Old Differential
Drain the differential fluid by removing the drain plug and collecting the oil in a pan. Next, unbolt the driveshaft from the differential. Support the differential with a transmission jack or similar tool. Remove the bolts securing the differential to the axle housing and carefully lower it.
Installing the Aftermarket Differential
Compare the new differential with the old one to ensure proper fit. Apply gasket sealant to the mating surfaces if required. Position the new differential into the axle housing and bolt it in place, tightening the bolts to the manufacturer’s torque specifications. Reconnect the driveshaft securely.
Refilling Differential Fluid
Fill the differential with the recommended gear oil through the fill plug. Use a funnel to avoid spills. Check for leaks and ensure the fluid reaches the proper level. Replace the fill plug and tighten it securely.
Final Steps
Reinstall the wheels and lower the vehicle. Reconnect the negative battery terminal. Test drive the vehicle to ensure everything operates smoothly. Check for leaks and recheck the fluid level after a short drive.
