NHTSA Complaint #716550 — 2000 CHEVROLET SILVERADO

THERE HAVE BEEN NO FAILURES, BUT I HAD TO PUT "ONE" IN AN EARLIER FIELD TO GET THIS THING TO WORK/SUBMIT. ISN'T IT BETTER TO KNOW OF A PROBLEM BEFORE AN ACCIDENT? ON PAGE 6-72 OF THE OWNERS MANUAL FOR 2000 SILVERADO TRUCKS IT INDICATES A WHEEL LUG SPEC. OF 140 FT LBS. THAT SEEMS UNUSUALLY HIGH FOR AN ALUMINUM ALLOY WHEEL (NORMALLY 80-100). I CALLED GM CUSTOMER SERVICE, AND THEY ON 12/23/99 CONFIRMED THAT NUMBER. I CHECKED THE ACTUAL TORQUE SETTINGS AS THE TRUCK WAS DELIVERED, AND NOTICED THAT MOST OF THEM WERE ABOUT 90 FT LBS. I CHECKED WITH MY DEALERSHIP TO SEE WHAT THE SHOP MANUAL INDICATED, AND WAS TOLD THAT THERE WAS NO REFERENCE IN THE SHOP MANUAL, BUT I SUSPECT THE SERVICE WRITER DID NOT KNOW FULLY ABOUT HOW TO USE THAT SCREEN. I AM GOING TO USE 95 FT LBS AS MY SPEC. I AM CONCERNED THAT 140 FT. LBS. WOULD RESULT IN A WHEEL LUG BREAKING WHEN IN A HOT AND STRESSED SITUATION. *AK
