Before starting the installation, ensure you have a clean workspace and all your tools ready. Safety is paramount, so make sure to wear safety glasses and gloves throughout the process.

Step 1: Lift the Vehicle

Using a hydraulic jack, lift the rear of your Ford F-150 Raptor and secure it with jack stands. Ensure the vehicle is stable before proceeding.

Step 2: Remove the Rear Wheels

Loosen the lug nuts on both rear wheels and remove them completely. Set the wheels aside in a safe location.

Step 3: Drain the Differential Fluid

Place a drain pan under the differential and remove the drain plug to allow the old fluid to drain completely. Replace the plug once drained.

With the differential fluid drained, you can now disassemble the differential housing.

Step 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.

Once the cover is off, you can see the differential assembly. Remove the pinion shaft bolt and slide out the pinion shaft. Then, carefully remove the old differential from the housing.

Installing the Kaas Industries LSD

Now that the old differential has been removed, it’s time to install the new Kaas Industries LSD.

Step 6: Install the New LSD

Carefully place the new LSD into the differential housing. Make sure it is seated properly and aligned with the pinion shaft.

Step 7: Reinstall the Pinion Shaft

Insert the pinion shaft back into place and secure it with the bolt. Ensure it is torqued to the manufacturer’s specifications.

Reassembly Process

With the LSD installed, you can now reassemble the differential housing.

Step 8: Replace the Differential Cover

Apply a new gasket or sealant to the differential cover and reinstall it, tightening the bolts to the specified torque.

Step 9: Fill with New Differential Fluid

Remove the fill plug and pour in the new gear oil until it reaches the fill level. Replace the fill plug securely.

Final Steps

With everything reassembled, you can now lower your vehicle and reinstall the rear wheels.

Step 10: Reinstall the Rear Wheels

Place the rear wheels back onto the hubs and hand-tighten the lug nuts. Once both wheels are on, lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

Step 11: Test Drive

After the installation is complete, take your Ford F-150 Raptor for a test drive. Listen for any unusual noises and check for proper performance of the new LSD.
