If you are looking to change the differential oil in your Toyota Tacoma 4×4, then we have the right guide for you. We know many do-it-yourself projects can lead to disappointment or frustration (or, worse!) damage, if you forgot a step, tool, or part that is necessary for the project at hand. This guide will help make sure that your differential oil change takes place without a hitch. So if you are ready to get this DIY project going, we will move right into our first step.
- Before setting up your vehicle for a differential oil change, lifting, supporting, and immobilizing it, you want to start this project right by checking to see if you have all your needed parts and supplies. In this particular project, you will need a 10mm hex socket for the differential’s fill and drain plugs, an oil drain pan, a hand pump for pumping oil, and a torque wrench if possible. The supplies you need consist of about one and a half quarts of 75W-90, and some PB blaster if needed for any plugs that are stuck.
- Once you have gathered all the necessary tools and supplies, you are ready for the doing-part of this do-it-yourself project. To reach your Tacoma’s differential, you may want a rolling mat or soft pad to lay on while working, to make it easier to focus on the project and not the searing pain from laying on rough asphalt. When you have made it under the car, with easy access to all your tools, you may notice something blocking your view of the differential’s fill and drain plugs. This is most likely the skid plate. You will need to remove this before proceeding with the next step of the process.
- After removing the skid plate, you will see two 10mm Hex or Allen plugs, one is the fill plug another is the drain. Start by moving the pan underneath the drain plug and removing the fill plug first, to make sure you can get it off while you still have oil in your system. Next, remove the drain plug and let it drain the old oil out. While it is draining, it would be the best time to clean the magnet on the drain plug. Once it is drained out, you will want to use the torque wrench and torque the drain plug to 48 lb•ft. Now grab the 75W-90 and your oil pump. Pump about 1.6 quarts of differential oil into the differential. The oil may begin to spill out slightly, so be sure to have rag handy to clean up any excess. Once the differential fluid dwindles to a few drips, clean off the fill plug and reinstall it, and torqueing it to 29 lb•ft.
- The last step is to just reattach the skid plate, and clean up the tools used for your differential oil change. Make sure to clear all tools out from under your car, so that you don’t create any problems for your tires or undercarriage. Once you’ve cleaned up, you are done!
The differential oil change has just these few steps to take that will take from old differential oil to new differential oil in just a few minutes. Remember to follow all torqueing pressures so as to not strip the plugs. As with all DIY projects, always use the appropriate safety tools while working on your car. If you follow these steps, and use all safety precautions, your differential oil change will be one more project you can cross off your list.
