bought an 05 avalanch a few weeks ago and was checking fluids. the fill hole bolt on the transfer case had to have been put in with an impact wrench. could not remove it even with a cheater bar. took the shoulders right off that aluminum bolt real good. have put alot of thought into this and came up with this....drill and tap the drain plug with a small diameter bolt so i can slip a rubber hose in and pump 2 quarts of fluid in the case.....is there a better way with maybe a special wrench to remove the round bolt which would be good?? have not looked any where for any ideas. just remembered an old oilpan plug which had a smaller plug in it. thanks for any and all answers...dpg ps. the drain plug was not screwed in as deep and came out
