I went to change my differential because it hasn't been changed since 76k miles and now I am at 213k. Ha! I don't have an impact wrench and between my 18" breaker bar, a pipe, and a floor jack all I was able to do is twist a 3/8" extension off in a 3/8 to 1/2 adapter. How bad do I need to change this gear oil? I want to drive this truck as long as possible. And if I do need to change it...next steps? Electric impact or 24" 1/2" breaker bar? Suggestions welcome.
thanks
