I've also seen somewhere someone wrapped the housing in b-quite or similar.
This is what I plan on doing when I drop mine to install an A/C condenser
and drier this weekend. Still haven't figured out how to attach them to the
radiator yet tho. Suggestions?

The problem could possibly be remedied (or at least greatly quieted) by
somehow using rubber mountings on the three fan-to-metal duct mount bolts,
or on the six metal duct-to-radiator mount bolts. I recently had mine off by
lowering the radiator (while still connected!), after removing the spare
tire/ holder. Note; I recommend removing the front bumper and dousing the 4
radiator mounting bracket bolts/ tinnerman nuts with penetrant before
attempting to remove the bolts from the mount brackets. A/C makes the job a
little tougher, trying to clear the lines, condenser, etc.
My fan is very loud and can be felt thru the floor when on high speed. I
recently rigged up a switch to manually force it into high speed operation,
as was recently discussed here.
HTH,
Mike B.
