Just pull the plug, let that drain, then crack the cover, drain out what comes, unbolt it, pry it open, drain, clean, reseal it, put it back together and refill... It's not hard, and doesn't take that long....

You have 3 options for sealers:

1. A cheap 1 time use gasket
2. A re-useable gasket
3. RTV it

Don't let anybody fool you jebby. It's a pain in the neck when lying on your back in your driveway. Much easier when using a hoist so you can walk under it. All very doable though. Some differentials have drain holes which makes it easier for sure.
Here's my experience:
Front
Rear
Reusable gaskets

The crude squeeze bulb pump system I used worked real well. There are small fluid pumps available which will also come in handy when changing your transmission and transfer case fluids.

Drain holes make a lot of sense. How often do you plan on changing the differential fluid though? Here's a transmission drain plug that can be installed. Might catch on something when offroading though. Wonder if you can buy covers with recessed drain holes in them. Considering it's Jeep, the answer is likely "yes".

I dont see why you cant pump it out tho if the tube can reach the bottom

fragile? there are big and strong gears. you need a superman's power to damage them with a rubber tube.

I used soft copper tubing. Rattled the gears a couple of times.
The tubing was easier to get to the bottom and stay there while I pumped. I wouldn't worry about any damage (copper versus steel - no challenge)

so its doable using a pump to pump it out without dropping the case?

The thing is one of the reasons the cases are designed like they are is so you pull the cover when doing the change. That way you are looking at what is going on inside the unit. You can inspect the gears and see what kind of crap is in there. It also allows you to clean out any residual muck in the case. It is a real easy job, even easier if you buy the re-usable gaskets. One trick is to drive the Jeep for a while before and get the oil warmed up helps it drain a lot faster, especially if it is cold outside.

what do you mean dropping the case? taking the cover off? i've always done it the way inferno said, drain, cover off, clean, reseal, refill. and rtv black silicone or even the high temp (which really isnt necessary on diffs) has always worked for me, my dad, and everyone i know who works on their own vehicles

I believe some covers actually come with drains. Works well for those in water a lot and doing frequent drains.

I did my Liberty and it was pretty easy. Get a big cardboard box to flatten out..It keeps you warmer than lying on the ground or concrete garage floor. I sprayed each bolt around the head with WD40 the eve before and let them "soak" They came off no issue. Put some anti foul on each bolt as you turn them back in and tighten in a star pattern slowly. The RTV will do fine. When you have the cover off an old toothbrush to swipe the bottom clean works well. Leaves a smile on the Jeep too...

I bought the Pluhs pump, the same people that make the grease guns. It looks just like a grease gun, big and heavy and industrial. I shove the tube down into the fill hole, (I used a wire coat hanger inside the plastic tube the first time to get the angles right, now the tube is set after leaving the coat hanger in there for 9 years!) and pump out the stuff, takes about 3 minutes and probably gets 97% of the stuff. Then I just pump in the new stuff. I can change the oil on both diffs in about 45 minutes.

My thought are if the seal isn't leaking, why mess with it unless you have to?

just drop the case. its pretty easy. only suggestion is avoid windy days and have news paper cover the ground if you work in your garage.
get the right sealant too. Black silicone sealant is recommended.

Seriously? Don't be lazy when it comes to vehicle maintenance you will regret it. You can do both diffs in an hours time what's the big deal? If you want to make it even easier on yourself get a set of lube locker gaskets and you won't even have to mess with RTV, doesn't get any easier than that. Don't pump it out, crack it open, make sure theirs no chips, cracks, or broken teeth, make sure theirs no metal shavings in the bottom etc... do it right or don't do it at all.

I have a set of g2 covers that I bought at 4wd.com they have drain holes on the bottom Great to drain the oil and not make a mess but it's still a good idea to pull them and see what's going on and wipe out the bottom of the case that's where all the crap lays

Good idea about using the coat hanger to shape the hose.

I ran into that hose problem with a $5.00 squeeze bulb pump setup. I ended up using copper tubing fastened to "shortened" tubing on the squeeze bulb pump. Worked great - patent pending.
