Any photos for diff and transfer case drain/fill plugs
I am planning on tackling the transfer case and differential drain and fill this weekend in the driveway. Does anyone have any photos of the exact plugs I need to remove as well as wrench sizes? I want to make sure I don't remove the wrong bolts. Also I will be replacing the fuel filter so any tips for that will help as well. 04 Sport 3.0 . Thanks in advance

04Sport, both are easy to access. To remove both of the plugs, you will simply need a 3/8" socket wrench. No socket will be required. The square end of the wrench fits into the plug. You may need a short extension (2" one at most).
As for the rear differential, get the rear end up in the air and find the rear differential. If you look at the differential, you will see structural "fins" on the outside of the case that is splitting it front to rear at the mid point of the differential. If you look just below that fin (on the driver's side as I recall), you will see a 1/2" NPT plug with a 3/8" square in it. That is your fill plug for the rear diff. Unfortunately, that is also your "drain" plug. You will need a suction pump to pull the fluid out of the rear diff. Once you get the old fluid out, you simply fill the rear diff until fluid starts to come out the hole.
As for the transfer case, this plug is a little difficult to find initially. BUt, once you find it, you will know where it is. Get the front of the car up in the air and locate the tranny and the transfer case. You will see about a 3" gap between the two. Looking from the driver's side, look at the side of the transfer case, in between the fins that are on the outside of the T-case. Near the bottom, you will see a plug identical to the one on the rear diff. That is your drain plug for the transfer case. Unfortuantely, this is also your fill plug too. But, I am sure you are aware of that already. This plug sits about 2" back inside the hole. So, not the easiest of things to spot with a quick look.

04SPORT, I used the Mobile 1 75W-140 full synthetic in my car. Had no issues with it. The big thing is to make sure you have the full synthetic stuff.
As for the fuel filter, the big trick with that is to push in on the connector and then insert the release tool. This will make getting it so it will release much easier. Also be ready with a rag since you will most likely loose a little bit of fuel as you break the second connection.

04SPORT: In this post, you'll find a couple pictures of the plug in the transfer case for draining and refilling the oil. Sorry that the quality is poor. It's the best I could do with an iPhone while lying on my back in the shadow of the car:

Here's another picture of the oil plug in a transfer case that's been removed from the car, as viewed from the US driver's side.
I found that a 3/8 inch breaker bar worked better than a 3/8 inch socket w/ extension. For tight spaces, the breaker bar has a smaller head and can reach into the oil plug recess by pivoting the head ~120 degrees to the handle. Jacking up both sides of the car took a lot more time and effort than actually draining and refilling the oil.
