by

Installing a limited-slip differential (LSD) in your Miata is a crucial step for enhancing its drift capabilities. This guide will walk you through the process step-by-step, ensuring that you have all the information needed to successfully complete the installation.

Tools and Materials Needed

  • Socket set
  • Wrench set
  • Torque wrench
  • Jack and jack stands
  • Limited-slip differential
  • Diff oil
  • Gasket sealant
  • Shop manual for Miata

Preparation

Before starting the installation, ensure that you have a clean workspace and all the necessary tools at hand. It’s also advisable to wear safety gear, such as gloves and goggles, to protect yourself during the process.

Step 1: Lift the Car

Use a jack to lift the rear of the Miata and secure it with jack stands. Make sure the car is stable before proceeding.

Step 2: Remove the Rear Wheels

Take off the rear wheels using a socket wrench. This will give you better access to the differential.

Step 3: Drain the Differential Oil

Locate the drain plug on the differential and remove it to drain the old oil into a suitable container. Allow it to drain completely before moving on.

Step 4: Remove the Differential Cover

Remove the bolts securing the differential cover. Carefully pry off the cover to avoid damaging the gasket. Set it aside for later.

Step 5: Remove the Old Differential

Unbolt the existing differential from its housing. Take note of any shims or spacers as they will need to be reused or replaced during installation.

Step 6: Install the New LSD

Carefully place the new limited-slip differential into the housing. Make sure it’s aligned properly and reinstall any shims or spacers that were removed.

Step 7: Reattach the Differential Cover

Apply gasket sealant to the differential cover and secure it back in place with the bolts. Ensure that it is tightened to the manufacturer’s specifications using a torque wrench.

Step 8: Fill with Differential Oil

Replace the drain plug and fill the differential with new oil through the fill plug. Check the owner’s manual for the correct type and amount of oil needed.

Step 9: Reinstall the Rear Wheels

Put the rear wheels back on and tighten the lug nuts securely. Lower the car back to the ground.

Step 10: Test Drive

Take your Miata for a test drive to ensure that the LSD is functioning properly. Pay attention to how the car handles during turns and acceleration.

Conclusion

Installing an LSD in your Miata can significantly improve its performance, especially for drifting. By following these steps carefully, you can ensure a successful installation and enjoy the enhanced driving experience that comes with it.
