On a beautiful clear Berkshire day while driving 70 mph on a busy highway truck began to experience "death wobble" so violently that it caused me to go off the road into breakdown lane and nearly lose complete control of vehicle. Luckily, being an experienced driver, I was able to keep my cool and steer out of it by not slamming the brakes on! Keep in mind, the truck has all new tires, wheels, front end components, brakes, front and rear shocks and rear shackles. It was a very scary experience and hope that it never happens again!!
