I have the same damn thing on my truck and I have traced it to the passenger
side y pipe where it connects to the JBA header. The metal "ring" on the
pipe with the bolts running through it that secure it to the header is what
is vibrating against the frame. I can even see a mark on the frame from the
rubbing. Maybe this is your problem? If it's not I could sure use help
with mine!!!

Yep, that was me... Let me know if it works. Joel suggested it might be
the exhaust down pipes rubbing and I might try moving them around a bit
next chance I get. This notion makes sense to me (even though I can't
*see* any contact marks on the exhaust) 'cause I installed headers on mine
and I suspect those down pipes ride just a hair lower with the shorties
installed.
Do you have headers on your 318 or are they still the stock manifolds?
Anyway, I'll shoot up a flair if I find out anything.

BTW, what's up with the "|" marks where a "'" should be in your
messages?... just curious.

Subject: DML: 4x4 Front end growl - Skidplates

Someone had noticed a problem with noise up front after installing new
skidplates. I think I know what was going on, since I just had the same
problem when I re-installed my skidplate under my new front diff.
Drum roll please...
The skidplate is contacting the bottom of the diff. Mine would only do it
under acceleration, when the frame evidently flexed enough to put them in
contact.
The fix? The front skidplate is pretty beefy plate steel. I think I´m going
to take a torch to mine to relax the steel a bit (it´s pretty beat up) and
take a really big hammer and beat on it.
