There are two plugs, A drain plug and fill plug.

The drain plug is on the lower left side "Driver Side" the fill is on the upper right side.

Think the size is 24mm or 25mm socket.

Do your self a favor and get a little hand pump $8.00 Pep girls, You will thank yourself and drive way.

I was able to use a six-point impact socket (it's what I had in that size). There's enough clearance for the thicker-walled socket to fit (that's not always the case).

You'll want to use a properly-fitting socket or wrench, as the plugs are of an anodized aluminum alloy, not steel, and their corners will round-off easily. I would not recommend using a "universal" tool like a Crescent wrench or vice grips.

You can see from that last picture that I'd had a small leak in my transfer case.

It was coming from that rear speed sensor.

The same dealer that keeps telling me that nothing is available, said there is no part No. for that o-ring. I bought an assortment of various o-rings at my FLAPS, and one fit perfectly: hard to install, but not so hard that installation sheared off half the o-ring.

I expect that will take care of that.

I had the same issue with my '95 (RIP). I just went down to the local McLendon's hardware and grabbed an o-ring off the shelf. The stock o-ring looked like it actually had a square cross-section, but that sensor never leaked from the time I replaced the o-ring until my Aero's untimely demise (about 5 years). That was a $0.99 solution and I paid way too much for that o-ring. The dealer just wanted to sell a new sensor at close to $100.
