"Death Wobble": Driving, driving, driving (yeah look at me, pass me up, its a fake M-16), apply brakes, between 30-45 mph brakes feel mushy and truck pulls to right slightly. Then if braking increases, the truck frame fees like its articulating and the tires feel like they're riding on railroad ties. Its happened to me so often that I anticipate it and once it starts, I apply less or more brake and steer left or right to maybe shift weight of truck to try to stop the wobble. Your first time will scare the **** out of ya, as in..."WHAT THE CR*P HAPPENED?!!" I noticed that the rate of pressure on the brake pedal has an affect on the onset of "Death Wobble" also.
