2001 Chevrolet Redundant Silverado 2500

2001 CHEVY 2500 HD TRUCKS ( FRONT WHEEL HUB ASSEMBLIES) LOOSING UP UNDER NORMAL DRIVING CONDITIONS. THESE ARE SEALED HUB UNITS SO YOU MUST PURCHASE BRAND NEW ONES AT A COST OF OVER $500-700 PER UNIT. I HAVE HAD BOTH SIDES LOSING UP ON ME AND NOW THE REPLACEMENT IS NOW LOOSE AGAIN AFTER 30,000 MILES. TO TEST THIS YOU MUST JACK THE WHEEL OFF THE GROUND AND PUSH/PULL ON THE WHEEL IT WILL ROCK BACK AND FORTH AS IF ITS READY TO COME OFF THE WHEEL ASSEMBLY. I WAS A MECHANIC FOR 9 YEARS SO IM NOT YOUR AVERAGE DRIVER WHO WOULD NOT NOTICE ITEMS SUCH AS THIS. I TAKE BETTER CARE THAN MOST FOR MY TRUCKS AND SEE THIS AS A MAJOR SAFETY FACTOR FOR ALL OTHER CHEVY TRUCKS ON THE ROAD. NOTE: THIS WAS AN EXPERIMENTAL HUB THEY USED FOR ONLY A COUPLE OF YEARS. NOW THEY WENT BACK TO THE ACTUAL BEARING NUT THAT YOU CAN TIGHTEN IF LOOSE....SEEM STRANGE HUH? MAYBE THEY KNOW SOMETHING AND TRIED TO KEEP IT UNDER THE TABLE??? *NM

2001 CHEVROLET SILVERADO HAS HAD A HISTORY OF PROBLEMS. *MR THE FUEL PUMP WAS REPLACED AND WAS DIAGNOSED BY K-S FUEL INJECTION AS BEING THE CAUSE OF THE ENGINE LIGHTS AND LOW POWER, THE WAS A FUEL LEAK IN WHICH THE REAR HOUSING WAS CRACKED AND LEAKING OIL, THE TRANSFER CASE AND THE DRIVESHAFTS WERE REMOVED, THE FRONT WHEEL BEARING WAS NOISY AND WAS REPLACED, THE UPPER BALL JOINT WAS BAD, AND A FAULTY "NSDU" SWITCH WAS REPLACED. *SC
