Thanks badger, that's what I was looking for. I was also gonna do the rear diff in my jeep cause I changed it a couple of years ago and put 75w90 royal purple in it and read after I changed it that if you tow with it to use 75w140. I pull a boat with it so I may try their diff lube also, if I can find it. I may just end up filling it with shell spirax.
Thanks

According to ECGS, never, ever use Royal Purple in your diff. All they do is gears and have a pretty good idea what works and what doesn't. They recommend Lucas oil, but Royal Purple is the only brand they say not to use. I use Lucas 85-140 in my Tacoma.
