Drive line noise mystery? Solved

Hahaha, that's terrific kryten! Me plums, oh me plums! I love that show. I'm glad they got back together on the new show "The Grand Tour"

Thanks Hammerhead the crash test dummy in the drivers seat had better be quick reacting. Or pick a spot to do it where the run away ramp ends somewhere safe and cheap to recover the truck. I used to do this by myself with a lot of extra time securing jack and frame stands. It's amazing how fast you can find that 1 drive tire thats mis-mounted or out of round just by watching the tires spin or that drive shaft that has a slight wobble to it.
