DRIVING ON 115TH ST AND I -57 OVERPASS IN CHICAGO & LEFT FRONT WHEEL ASSEMBLY CAME OFF WHEN THE A-FRAME BROKE AND WENT ACROSS 2 LANES OF TAFFIC . THIS IS A 2004 FORD F-150 WITH 59,354 MILES. NO WARNING WHEN IT HAPPENED. THE VEHICLE SLID TO THE RAILROAD TRACK AND FLIPPED SIDEWAYS PARALLEL TO THE TRACKS AND RT. FRONT SIDE A-FRAME BROKE. THERE WAS EXTENSIVE FRONT END DAMAGE AND BACK OF CAB HIT BED AND CREASED ABOUT AN INCH DEEP, BUCKLED THE BED ABOVE THE WHEEL 3 INCHES. BENT THE FRAME & INS. CO. SAID IT WAS NOT TOTALED BUT HAS BEEN 10 WEEKS PLUS AND THEY ARE STILL WORKING ON IT. NO OTHER VEHICLE INVOLVED. FORD REFUSED TO LOOK AT IT. THE DEALER WOULD NOT TURN IN A CLAIM ON THE COMPRHENSIVE WARRANTY FOR 72 MO OR 100,00 MILES. SO WE ARE STUCK AGAIN-NO VEHICLE FOR OVER 10 WEEKS AND STILL NOT REPAIRED. BODY SHOP IS STILL PUTTING PARTS ON IT. HOW MANY OTHERS HAS HAD THIS HAPPEN? *JB
