Step 8: Reattach the Differential Cover
Apply gasket sealant to the differential housing and position the cover back in place. Bolt it securely, ensuring a proper seal to prevent leaks.
Step 9: Refill with Differential Fluid
Replace the drain plug and refill the differential with new fluid through the fill hole. Make sure to use the recommended type and amount of fluid as specified in the vehicle manual.
Step 10: Reinstall the Rear Wheels
Put the rear wheels back on and tighten the lug nuts securely. Lower the vehicle back to the ground using the jack.
