Recommended Diff Fluid for rubicon
I read a couple write ups, but want to be 100% sure on what weight gear oil to use for the rear Rubicon axle.
I read to use Royal Purple 75W90 Synthetic Gear Oil.. is this correct..?
How many quarts do I need?
Do I need any special oil for the lockers?
Any help would be great.

Front diff calls for 80w90 2.7 pints, rear calls for 80w90 unless you plan on towing stuff, if you tow you use 75w140 4.75 pints and add 3.4 oz of limited slip additive.

According to the write up the front takes 1.35 quart and the rear takes 2.375 quarts. I just changed mine again this past weekend. I also use Royal Purple. You don't want to over fill the diffs. It will run out the breather tubes and smell to high heaven for a couple of weeks. Found out the hard way the first time I changed them. No problems this time though.
