I heard a racket that I first thought was a u-joint. Was downshifting at the time, traveling about 35-40. Once I turned it got worse so I pulled over to investigate. No loose pulleys that I can see. What else could it be besides a rod knocking? No smoke, good oil pressure and engine temp. Truck is a 99 CH600 with 350 with Super 10.
