EASY RETURNS
Inevitably your off-road vehicle will take turns out on the trail or rough terrain. The last thing you want is your differential causing you problems or worse, a roll over. Just like the engine oil, differential oil needs to be replaced every so often. 4WheelParts.com has all the right tools you need to replace differential oil and the differential drain plug.
Changing Differential Oil
Warm the oil in the differential by driving for a few minutes. Set a wide collection pan to catch the foul-smelling oil on top of a drop cloth to avoid staining your driveway. Remove the differential fill plug from the casing then unscrew the drain plug. Using a flathead screwdriver carefully remove the cover letting the oil drain out slowly. If you pry the cover off too fast, the oil will gush out and you'll have a big mess on your hands. Once the oil has drained, wipe the interior with an old rag. Avoid cleaners as their residue can interact with the clean oil. Use either a gasket or liquid gasket to seal the housing before closing it back up. Use a torque wrench to tighten up the bolts then fill completely.
Replace the Drain Plug
To extract a bolt that has rusted to the housing, drill a hole in it. A little oil sprayed on the plug keeps the drill bit from getting too hot and metal from flying everywhere. A blow torch will heat up the metal to help loosen the bolt for easier removal. Use a reverse threaded bolt in the hole created by the drill bit to get the plug out. If added heat doesn't work, you can alternate that with a few taps on the plug to loosen it up from the surrounding metal. Be sure the bolt is out if you decide to hit the plug. Replace using a differential drain plug kit.
