Solid covers on D30 & D35 - fluid capacity?

I am about to do a fluid change on my TJ and in the process putting on Solid covers & lubelockers - what I want to know is, does my capacity change? How much lube should I be putting in? Is there a way to check the level with the fill hole moved up like it is or do I go with a fluid measurement?

Nope the fluid capacity is the same as with a stock cover, DO NOT overfill the diff or you will end up having diff fluid blow out the breather hose, and the fluid can foam causing a lack of lubrication on the gears, fill with the same amount of fluid as you normally would. If you have adjusted your Pinion angle for an sye/cv ds I have heard that you can put a little bit more fluid in to compensate for the adjustment but i really wouldn't advise more fluid then whats advised in the FSM.

I don't know what the dana 35 takes, but I know that the dana 30 takes around 11/2 quarts...be careful not to overfill, or you will have a big mess.

I run 75/140 because I wheel my jeep, so I wanted a thicker gear oil, however 75/90 is just as fine and would work as well. 75/140 is recommended in the FSM if you are going to be using your jeep to trailer anything, they also say that 75/90 is the reg for your diff if your not trailering anything.

I run the 75/140, as that is what ARB recommends for offroad use. Royal Purple seems pretty good, its only a few extra bucks.

I do plan on a bit of wheeling, but realistically will probably only be able to get out a weekend per month over teh spring/summer/fall - do you recommend 75/140 or 75/90 then?

Honestly it's really a choice up to you, I have had no ill effects with the fluid becoming heavy or thick in cold weather and like I said I am running 75/140, but I do not know how cold MI is getting this time of year.

In the teens to early 20s, very little below 10. We will be back in the 30s again shortly however.

Hoping to do the axles on my tj this weekend.
I plan to use regular lube and agree with amounts listed above.

I plan to remove the covers to check things out. When reinstalling the covers is there a gasket to use or just rtv?

Question #2
Plan to drop the pan on the trans and change the filter. How much fluid will drain out?
