Rear Differential Fluid change

The first step in replacing your rear end differential fluid is to jack the rear end of the vehicle up into the air. Be sure to use safety precautions so that no injuries occur. With the vehicle in the air you will have clear access to the rear differential. If you want to check the current fluid level you can pop off the rubber plug, if the level is full the fluid should be directly below the level of the plug. If it is lower then your are currently low on fluid. To replace the fluid inside the diff you must remove the plate and allow for the fluid inside to seep out. Be sure to have a container to catch the fluid. Once the fluid stops flowing you can reinstall the plate by using some silicon sealant to help prevent leakage. The bolts for the plate should be torqued to 30 ft-lbs. With the plate reinstalled you can now take your new fluid and fill the rear end up through the rubber plug hole. Once done reinstall the plug and ensure that there are no leaks.
