AFTER HITTING A BUMP, THE STEERING WOULD SHAKE SO BAD IT WAS HARD TO HOLD THE STEERING WHEEL. HAD TO PULL OFF ON THE SHOULDER TO GET THE SHAKING TO STOP. AFTER HAVING THIS HAPPEN SEVERAL TIMES IN ONE DAY, I TOOK THE TRUCK TO DEALER WHERE THEY DISCOVERED IT HAD A BAD STEERING BOX. STILL WAITING ON THE TRUCK TO GET OUT OF SHOP.
