NHTSA Complaint #10454783 — 2008 CHEVROLET UPLANDER

I HAVE A 2008 CHEVY UPLANDER WHICH HAS DEVELOPED A SEVERE BANGING OF THE REAR AXLE THROUGH THE REAR TAILING ARM BUSHING THE MANUFACTURER IS WELL AWARE OF THE FAILURE OF THE REAR TRAILING ARM BUSHINGS IN THIS VEHICLE AND WITH ALL MODELS WITH THIS TYPE OF REAR AXLE. THE VEHICLE SOUNDS AS IF SOMEONE IS POUNDING ON THE BOTTOM OF THE FRAME WHENEVER I HIT ANY SIZE BUMP AT ANY SPEED. I KNOW THAT THE MANUFACTURER IS AWARE OF THIS SPECIFIC PROBLEM BECAUSE CHEVY HAS ISSUED A REVISION TO THEIR MECHANICS REPAIR MANUAL WITH AN ADDENDUM NUMBERED PIT3323E. WHICH STATES THAT:" IF NO PROBLEMS ARE FOUND WITH THE REAR SUSPENSION COMPONENTS AFTER THOROUGH DIAGNOSIS THEN REPLACE THE REAR TRAILING ARM BUSHINGS" THIS ADDENDUM GOES ON TO STATE THAT "A VISUAL INSPECTION OF THE REAR TRAILING ARM BUSHINGS MAY SHOW NO FAULT" I BELIEVE THAT I SHOULD HAVE THIS DEFECT REPAIRED FOR FREE OR AT A DISCOUNTED PRO RATED CHARGE.BUT, NO I AM DROPPING THE CAR OFF TOMMORROW TO HAVE THIS REPAIRED AT THE COST OF $ 380.00. I FEEL THAT A T.S.B. SHOULD BE ISSUED SO THAT OWNERS OF THESE CARS SHOULD HAVE THEIR REPAIRS DONE AT A FAIR PRORATED CHARGE.UNFORTUNATELY ITS TOO LATE FOR ME BECAUSE THE NOISE AND JARRING OF THE BODY UPON HITTING A SMALL PEBBLE IN THE ROAD HAS BECOME UNBEARABLE AND I HAVE TO BITE THE BULLET,IF ONLY FOR MY OWN SANITY. OH, P.S. I HAVE REPLACED TWO SETS OF SHOCKS IN THE REAR SINCE THE DEFECT WAS IMPOSSIBLE TO DETECT BY ANY MEANS, WHETHER IT BE A VISUAL INSPECTION OR BY JACKING UP THE REAR AND PHYSICALLY MANIPULATING AND TRYING TO OBSRVE THE OPERATION AND ACTION OF THE AXLE TO DUPLICATE THE NOISE. NO SUCH LUCK!!!!!!!! *TR
