I know that there is a drain plug in the front differential housing, but for the life of me I cannot find it with the skid plate (belly pan) on. I have the aftermarket pan that comes with the Superlift. I thought I read somewhere that you could get to the drain without removing the pan. Reason being, a couple of the flush mount hex screws that hold the pan on are slightly rounded out and I don't want to make them worse by trying to remove. Can I get to the plug and remove it to drain the lube with the pan on?
