Using this rear differential cover is easy. First, make sure your vehicle is the right fit as specified in the product description. Then, carefully install the cover following the standard installation procedures. When it comes to maintenance, regularly check the oil level through the fill plug. Every so often, use the magnetic drain plug to drain and replace the oil to keep the gears well - lubricated. The magnetic drain plug will catch metal particles, which is great for the long - term health of your differential. Be gentle when handling the stainless steel Allen head cap bolts to avoid stripping them. And since the cover has a re - usable Viton O - Ring, you don't have to worry about buying new gaskets all the time. Just clean the O - Ring properly when you're doing maintenance. Enjoy the cooler and more efficient operation of your vehicle's differential with this cover!
