So I have the 4406 swap. Now after a few years the rear seal is leaking. Nothing major, slight drips, just want it fixed. I'm not really sure what the tcase came out of and I think the driveshaft was out of an Expedition. I can look up a mid 90's F-150 or 250s and find a 4406 seal but there are about 10 different combinations. Anyone know a part number to replace it with? If I pull it out I'm sure there will be a part number on it but I would rather have it in hand before I took it out to make it simple.

It would also be nice to know what vehicle to look up in the future for a quick reference on the tcase since most stuff is looked up by vehicle now.
