Overfilling a little bit is no big deal. JKs have semi-floating rears, so the net level isn't really that much higher by overfilling a small amount as most of it will run down the shafts to lube the axle bearings. If you had a problem with cavitation, you would mostly likely be getting a drip or two out of your vent tube.
I'm .5 quart over in front and 1.0 quart over in the rear with SOLID covers and rear pinion angle corrected with rear UCAs.

I hate asking this question, but I have yet to find the correct answer, I know there has to be one. I used the search function, there are thousands of posts with different answers on how much to fill the diff (44 front and rear) with the solid covers. Solid states 1.5-2.3(whatever that means), some say 1.5, some say 1.3, some say "little less that two". What is the correct answer? Also, is it ok to use 75w90 in the front and rear, manual states to use 75W140 in the rear?
This is my plan when i have my ARB diff coveres installed!
