I had to remove the differential on my 1998 GMC Jimmy 4x4 in order to drop the oil pan. I have re-installed the oil pan and I am having MAJOR difficulty with the re-install of the differential. I'm sure that it has to go in at a certain angle in order to fit. Maybe I'm just not holding my tongue right or the stars aren't in the right alignment yet. Does any one have any experience on installing one of these and what is the trick?? I could really use the help!!!!!!!
