NHTSA Complaint #10296301 — 2007 CHEVROLET SILVERADO

THUMP AFTER COMING TO A STOP. AFTER ABOUT 24,000 MILES. I STARTED FEELING A LIGHT THUMP FROM THE REAR, AS IF SOMEONE BUMPED ME FROM BEHIND. OVER THE NEXT FEW WEEKS IT BECAME VERY NOTICEABLE, SO I TOOK IT TO THE DEALER FOR INVESTIGATION. THE 1ST TIME, THEY SAID THE REAR-END HAD THE WRONG LUBE IN IT & THEY REPLACED IT. THIS SEEM TO WORK FOR THE NEXT SEVERAL WEEKS. THEN THE THUMP RETURNED LIGHTLY AT 1ST & GRADUALLY WORSENED TO A MAJOR THUMP. I RETURNED IT TO THE DEALER & THIS SECOND REPAIR WAS THAT THE LUBED THE REAR-END & REPLACED THE YOKE ON THE DRIVESHAFT. THIS REPAIR WORKED FOR ABOUT A WEEK & I STARTED FEELING THE LIGHT THUMP AGAIN. I TOOK IT BACK IN AGAIN, LEFT IT ALL DAY & THEY APPARENTLY DROVE IT AROUND THE PARKING LOT & COULDN'T DUPLICATE THE PROBLEM. ONE OF THE SERVICE MANAGERS RODE WITH ME, AROUND THE PARKING LOT & THE PROBLEM WOULDN'T SHOW UP. IT HAS SINCE WORSENED AGAIN & I WILL TAKE IT BACK IN ONCE THE PROBLEM GETS A LITTLE WORSE. *TR
