The Nissan GT-R is renowned for its performance and handling capabilities, especially when tuned to 600 horsepower. One of the key components that enhance its performance is the limited slip differential (LSD). Installing an LSD can greatly improve traction and handling, allowing for better acceleration and cornering. This guide provides a step-by-step installation process for a limited slip differential on a 600-hp Nissan GT-R.
Tools and Materials Needed
- Limited Slip Differential
- Socket set
- Torque wrench
- Jack and jack stands
- Wheel chocks
- Diff oil
- Grease
- Replacement gaskets
- Shop manual for specifications
Preparation
Before starting the installation, ensure that the vehicle is parked on a flat surface and the engine is off. Engage the parking brake and place wheel chocks behind the rear wheels for added safety. Gather all tools and materials required for the installation.
1. Lift the Vehicle
Using a jack, lift the rear of the vehicle and secure it with jack stands. Ensure the vehicle is stable before proceeding.
2. Remove the Rear Wheels
Using a socket set, remove the lug nuts and take off the rear wheels. This will provide better access to the differential.
3. Drain the Differential Fluid
Locate the differential drain plug and remove it to drain the old fluid. Allow sufficient time for all the fluid to drain out before proceeding.
4. Remove the Differential Cover
Using a socket set, remove the bolts securing the differential cover. Carefully pry the cover off, ensuring not to damage the mating surface. Clean any old gasket material from the differential housing.
5. Remove the Old Differential
Once the cover is removed, you can access the differential. Remove any retaining clips and bolts holding the old differential in place. Carefully slide the old differential out of the housing.
6. Install the New Limited Slip Differential
Before installation, apply a thin layer of grease to the gears of the new limited slip differential. Slide the new differential into the housing, ensuring it is properly aligned. Replace any retaining clips and bolts, tightening them to the manufacturer’s specifications.
7. Replace the Differential Cover
Install a new gasket on the differential cover. Carefully align the cover back onto the differential housing and secure it with the bolts. Tighten the bolts evenly to avoid warping the cover.
8. Refill with Differential Fluid
Replace the drain plug and refill the differential with new fluid through the fill hole. Use the recommended fluid type and quantity as specified in the shop manual.
9. Reinstall the Rear Wheels
Place the rear wheels back onto the hubs and hand-tighten the lug nuts. Lower the vehicle back to the ground and then use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
10. Test Drive
Before taking the car for a test drive, double-check all connections and ensure there are no leaks from the differential. Once satisfied, take the vehicle for a short drive to ensure that the new limited slip differential is functioning properly.
Conclusion
Installing a limited slip differential on a 600-hp Nissan GT-R can significantly enhance the vehicle’s performance. By following these steps carefully, you can ensure a successful installation. Remember to always refer to the shop manual for specific torque settings and fluid specifications to maintain the integrity of your vehicle.
