So you're saying you know where to put it? :P
Yeah, you can run 75W140 in the differential. I've been using Redline 75W140 for two years. Works great, provided that you're using it for the right reasons (i.e.: aggressive sustained driving, or a very worn differential). If you don't have a reason to run 75W140, you should follow the manual's recommendation: 75W-90.
