I have 96 Explorer 4.0L 4wd Control Trac. I removed the transfer case
drain pug and I noticed something like teflon paste on the threads. The
Chiltons manual doesn't mention anything like it in the drain/refill
procedure. Do I need to be concerned with this? tia

Sounds like teflon plumbers tape, the modern pipe dope. I wouldn't
think it's necessary, the transfer case isn't under a lot of pressure
like a water pipe is.
But it wouldn't hurt to use it, I guess...

This stuff is applied at the factory as added insurance against unseemly
leaks on a brand new vehicle.

The reasoning..... these units are not assembled in the same building (or
possibly even in the same state/province/country) as the truck. The units
are filled with lubricant at the time of manufacture and all the external
opeings are plugged well enough to avoid ANY possible leaks. We have no idea
of the juxtaposition of these subassemblies during shipping or storage. A
little thread sealant on the threads will ensure no unsightly blemishes.

It certainly can't hurt to use a thread sealant on the plug when it is
reinstalled.... there is, however, no requirement for it and properly
tightening the plug (after cleaning the old thread sealer off), should give
a leak free installation.

I put it back without any sealant. I wasn't sure if it was some kind of
space age special purpose sealer ford used. maybe next time i'll use a
little teflon paste. Thanks for response.
