Well I remembered another one. I was working at the Dodge dealership at the time (took a brief break form fords) we had a ram charger come in that had an awful noise coming from the rear. A very load and substantive CRACK when accelerating after a stop. The car had been to at least 4 dealerships. you could see the different colors of RTV round the rear cover plate and the transfer case. We had every mechanic in the garage take it out bring it back check it on the lift. They all though it was the chain in the full-time 4 wheel drive transfer case. Well old johnny the dealer principle had to be in his 60's said he wanted to take it out for a drive.
Well he comes back has one of the guys put it on the big lift and says run it up high so we can all get under with out ducking. Everyone gather around he grabs a 6 foot pry bar we had in the corner and whack the heck of the spare tire hanging underneath the rear pan. CRACK turns out the plate that held the tire was upside down and allowed the tire to slide about an inch then the plate tip up with all the weight of the tire and the force of acceleration and CRACK. Well he had a mechanic take it apart and flip the plate and rerivet it all back together no more noise happy customer and KUDOS for the boss.
I'D RATHER GO SLOW THAN NOT GO AT ALL
