2000 FREIGHTLINER FLD120 Tires Problems

THE LEFT REAR FRAME RAIL IS TWISTED, BENT AND SAGGING CONFIRMED BY 4 FRAME SHOP INSPECTIONS CAUSING THE LARGE TRUCK TO HANDLE WITH DIFFICULTY AND SAFELY. THIS IS CAUSING UNNECESSARY RAPID TIRE WEAR AND IS A DANGER TO THE PUBLIC ON THE ROAD. FRIEGHTLINER HAS SAID BY THEIR OWN DISTRICT SERVICE MANAGER, PAUL NEWMAN, THAT THIS IS A NON-ISSUE AND AFTER ALL THE PROFESSIONALS REPORTS HE, THE DSM, SAID HE SEES NOTHING WRONG AND WILL THEREFORE NOT REPLACE THE TRUCK WITH A BUY-BACK NOR WILL HE AUTHORIZE ANY REPAIRS. HE, PAUL NEWMAN, OFFERED US 2 NEW STEER TIRES AND ANOTHER (4TH) ALIGNMENT JUST TO SEE WHAT HAPPENS. THIS VEHICLE HAS TO BE WRESTLED TO DRIVE BETWEEN THE LINES ON THE ROAD WHEN IT IS PULLING A LOAD AND THEREFORE IS A DANGER TO NOT ONLY THE DRIVER BUT THE GENERAL PUBLIC. THE TIRES SHOULD NOT NEED REPLACING UNTIL AT LEAST...
