Re: Transfer Case Drain Plug
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.
