VEHICLE SPEED CONTROL
DT*: THE CONTACT STATED THE SPEEDOMETER DISPLAYED AN INCORRECT READING UP TO 10 MPH MORE THAN THE DRIVEN SPEED. THE VEHICLE WAS SEEN BY A DEALER, WHO DETERMINED THIS WAS DUE TO THE OVERSIZED TIRES ON THE VEHICLE WHICH AFFECTED THE OVERALL TELEMETRY. THE VEHICLE WAS SENT TO AN INDEPENDENT REPAIR SHOP AND AN AFTER MARKET HYPER-TECH COMPUTER CHIP WAS INSTALLED TO OVERRIDE THE COMPUTERIZED TELEMETRY OF THE VEHICLE. UPDATED 05/30/06. *AK

SUSPENSION:FRONT:SPRINGS:LEAF SPRING ASSEMBLY
SUSPENSION MADE A 'THUNKING' NOISE WHILE DRIVING OVER BUMPS. I TOOK IT INTO THE DEALER AND WAS TOLD THE R. REAR TENSIONER LEAF SPRING WORN OR WAS WORN AND NEEDED REPLACEMENT. I NEVER GOT A STRAIGHT ANSWER AS TO WHY, BAD METAL OR WHAT? I'VE NEVER TOWED ANYTHING AND HAVE NEVER HAD ANY HEAVY LOADS IN THE BED CAUSING OVER COMPRESSION OF THE LEAF SPRINGS. TRUCK HAS ALWAYS SEEMED TO LEAN TO ONE SIDE AND LOOKS LOWER THAN FACTORY HEIGHT. DEALER FIXED UNDER WARRANTY. IT NOW SEEMS TO BE MAKING A SIMILAR NOISE BUT FROM THE FRONT SUSPENSION AREA WHILE DRIVING OVER SPEED BUMPS AND INTO DRIVEWAYS. I HAVE TO VERIFY THIS AND GET IT BACK INTO THE DEALERSHIP FOR MORE WORK...AND TRY TO GET ANSWERS. *JB
