Ive got a G80 with about 150000 miles on it. Wanted to change the rear diff oil but I cant get the plug out. Broke off a 3/8" extension in it. I plan to get an impact extension and trying a impact gun but im not sure im going to be able to get the broken off extension out of the plug.
What are my options? Are there cheap covers out their with fill plugs built into them? I cant find any. What about installing some kind of fill plug into my stock cover?
If you can remove the broken tool piece from inside the plug I'd use a torch and heat up the area around the threads before trying to remove it again. Also don't use an impact wrench with this type tool, a long breaker bar with some heat applied would work much better imo.
