I HAVE 29,222 MILES ON MY 04 PONTIAC GTO WHEN THIS HAPPENED THE FIRST TIME. OVER TIME ALL 6 BOLTS THAT HOLD MY HALF SHAFT TO THE RIGHT REAR WHEEL HAD BACKED OUT IT LEFT ME STRANDED IN A BUSY INTERSECTION RIGHT WHEN I GOT OFF THE FREEWAY. I5 AND 17TH ST. WITH NO BOLTS HOLDING THE HALF-SHAFT IN IT WAS FREE TO SPIN FREELY AND HIT OTHER PARTS UNDERNEATH MY CAR, DAMAGING THE AXLE, AND RIPPING THE BOOT. I RESEARCHED, AND FOUND OUT THIS HAS BEEN A COMMON PROBLEM WITH THE EARLY PRODUCTION 04 MODELS. I TOLD THE DEALER THIS AND THEY REFUSE TO REPLACE THE PARTS UNDER WARRANTY. THEY TRIED BLAMING ME BECAUSE I HAD INSTALLED DIFFERENT REAR SPRINGS, AND SAID I HAD REMOVED AND RE-INSTALLED THESE BOLTS FOR THE SPRING INSTALL. THESE BOLTS DID NOT NEED TO BE TOUCHED DURING THE SPRING INSTALL, I'VE TRIED EXPLAINING THE INSTALL TO THEM, BUT THEY WONT LISTEN... HORRIBLE SERVICE... *NM
