For you guys that have never done a transfer case, fluid change on your JL, do know that you have a skid plate that will be in the way when you go to drain the transfer case...

Some guys/gals will pull the skid plate, but it is far easier, to fashion something like this to facilitate draining..

You place this between the drain hole and the skid plate.... you pull the plug and the fluid runs along it, and then into the drain pan. No big mess on the skid plate and no pulling the skid plate.

This is an aluminum foil pan you get at the dollar store, etc.. You just cut the shape and fold up the edges. It's about say 16" long and about 4-5 inches wide. Easily cleaned when you get done so you have for next time...

So I got to wondering if you did climb under your Jeep and low and behold your new Jeep has a destroyed fill plug, what are you going to do. Not change the fluid and just keep driving it, or are you going to find a way to remove it?

If you ahead and remove and replace the destroyed fill plug, did it really matter that you pulled it first or last? I know what I would do even if I couldn't get the plug out.
Well, I can drive it over to Autozone or Napa to get what I need, so there's that.

If your dain plug is messed up and you can't get it out, Autozone probably will not be able to help you.

The point that flew right by you is that it can still be driven. And I'd have plenty of time to figure it out, since I change the fluid much earlier than it needs to be changed.

How somebody does this shouldn't give anyone else a painful rectal itch.

All this talk makes me glad I installed ARB covers with drain and fill holes.

How is that different than stock? There are drain and fill plugs in the OEM covers.
Well...the drain is in the housing... that's where this convo was going. If you cause enough damage to the housing drain fastener it can be a problem.

Just wanted to reiterate:

The tops of the Valvoline FlexiFill gear oil pouch's , DO screw right off/on.....

DO, save the empty FlexiFill pouch's and squirt cap for future diff fluid changes, especially, if you think just possibly you will buy gear oil (any brand) that does not come in a pouch.

That did not fly past me. The fact is it still has to be addressed be it today, next week or next year. I doubt that anybody really cares how someone changes their diff fluid. I would bet that thousands of Jeeps right now are running the diff fluid that came in the Jeep and have over 100,000 miles on them. Usually the only people that change out diff fluid are the ones that are off roading them.
