Customer complained of a horrible scream at cruise and above. The truck was happy to make the cacophony on the dyno. So I grab a sounding bar and a hose, and crawl around nnderneath while a compadre drove it. No tranny noise, carrier bearing OK. Sounds to be from the rear, but the diff and wheel bearings OK. So I switch to the hose-thescope. The tailpipe was right behind the rear wheel, where any little puddle would get sprayed on the tailpipe, and make rust. Swiss cheese. Sort of like a Flute. So I whip the rag out of my back pocket and start to play. :^) My buddy the driver didn't have a clue what was going on, was about to have a fit. Or maybe a Jig?
