Easy way to fill Diff.
Cut a section of clear tubing from Home Depot's plumbing section to length, put a funnel in one end and put the other end into the fill hole. Held the funnel up and poored in limited slip additive followed by gear oil until it started to drizzle out. put the plug back in and I was done, very little mess. Never had to get out the ramps or the jack and stands.. hope this helps someone
