Hello, I was working on my rear differential and was trying to get off the filler plug with an 3/8" extention but the plug was so tight i damaged or rounded the square hole. How can I fix it so i can get it off its very tight. I already removed the old fluid and i need to get new in.

gbrown - That's a drag. If it's totally rounded Mac tools make extractors that could help you get it out. Worst case is you will need to drill it out then replace the plug.
