The fill plug for the rear differential is stripped in the differential. I have tried pb blaster using heat and a few other ways to get it out and it won't budge. So I am thinking about adding a universal fill plug to the back cover when I have it off. Has anyone tried this? Is it a good idea or bad? Any help would be greatly appreciated. It's an 02 trailblazer.
