Check engine light on , and a loud clunking in the front passenger side . They put a new sensor in , an no difference at 26,000 they replaced the turbo it ran good for a week or so but fuel mpg never improved and it slowly lost power again , and all the other issues still remain the same. I got under the truck and had to locate the problem and found that the leaf spring was loose and caused the bushings to be destroyed, they wouldn't fix any of it , and I paid for a 2000 extended warranty . Im currently trying to get other owners of the 6. 0 diesel motors to get together a file a class action suit .
