DRIVING DOWN THE HIGHWAY AND HIT A BUMP IN THE ROAD THE TRUCK STARTED TO DO THE DEATH WOBBLE AND SHAKING UNCONTROLLABLY. I HAVE TO SLOW DOWN AND JERK THE WHEEL TO GET IT TO STOP. ITS INCREASINGLY GETTING WORSE AND NOW DOING IT AT LOWER SPEEDS AROUND 25- 30MPH. THIS HAS ALMOST CAUSED WRECKS WITH VEHICLES REAR ENDING ME, OR WOBBLING IN THEIR DIRECTION. IT ALSO HAPPENED IN A NEIGHBORHOOD WITH CHILDREN PLAYING, I THOUGHT I WAS GOING TO HIT THE KIDS! THE BRAKES ALSO FAIL WHILE BEAKING AND HITTING A BUMP. THE TIRES ARE AT THE RECOMMENDED PRESSURE AND THAT IS NOT THE PROBLEM. THIS IS A VERY COMMON PROBLEM AS I HAVE SEEN WHILE DOING MORE RESEARCH. IM AFRAID THIS WILL EVENTUALLY CAUSE THE TRUCK TO ROLL OR WRECK. DONT LET THE LOSS OF LIFE OPEN THIS INVESTIGATION AGAIN.
