Btw, there is two stacked on top of each other. I took one out. The picture shows only one seal, but it originally had two seals stacked on top of each other facing each other. The Timken seal appears to be identical in outer diameter and inner diameter, it just doesn't have those raised spots that the original has.
It is a double seal for the input shaft of the transfer case. The original P/N is MD704164 but that's been superseded by P/N MR145502. Here's a web page for the latter.

The seals are installed back-to-back, or bump side-to-bump side. Behind the inner seal is a thin, shim-like baffle plate.

Also I made a PDF of the parts list. Just need to see if it will upload.
