From the sensor thread: Looking back over the years I'm lucky to still be alive. In feeders when the tractors still had shutters on the radiator a electric wire of some sort was caught in the shutter mechanism & shorted out catching the insulation and what not on fire filling the cab full of smoke in a summer thunder storm in rush hour traffic in a construction zone. The burning wires melted the air line to the hand valve too that caused a major air leak. Thank God I was going up hill and was able to get out. In package I've had the rear axle shaft come out of the housing that had been written up for bad squeaking or chripping noise but was signed off as OK to run. If you want a thrill have the tie rod end break or come apart on a rough road! Does anyone remember the 1st P500's that had the A-frame front end(GM). When the U bolt broke you had very little control when using the brakes. I also had the gas tank fall out of a P400's & P600's when the cradle broke off the frame. I was lucky the tank did not leak or I would have been the 1st UPS terrorist truck bomber. Have you ever had a standard transmission self destruct at 50 mph? The good Lord was protecting me that day because none of the sharpnel hit the gasoline fuel line. The old P300's (535XX)did not have duel brake system so if a line or brake cylinder broke you had no hydraulic brakes. At least the hand brake would slow you down and Leaving myself an out saved a major pile up! I think this is a good starter! I'm sure everyone can share something that has happened to them!
