Steel plugs in aluminum!

[kavanagh@kodak.com (David Kavanagh staff)]

Help! I'm having problems finding the right method to loosen the drain plugs
from my rear diff! I replaced the fluid in my tranny a month or more ago, and
didn't have these kind of problems! I can't seem to get the front drain
plug or the fill plug to budge. I've applied moderate heat (propane for
short durations) and buggered up the hex in the plug as much as I dare before
trying something else. Is there something that will chemically free these
plugs from that aluminum housing?

PS. the "right" method is the one that works! :-)
