2005 SPARTAN K2 Steering Problems

THERE HAVE BEEN TWO SPARTAN K2 RECALLS ON STEERING RELATED ISSUES ON 2005 UNITS.05V283000 AND 07V300000 THESE ARE DEFECTS IN STEERING LINKAGE AND SPACERS THAT CAN CAUSE STEERING FAILURE. I AM TOLD BY SPARTAN THAT MY K2 IS NOT AFFECTED BY THE RECALLS. HOWEVER, MY UNIT HAS HAD A STEERING DEFECT SINCE DAY ONE. WHEN MAKING TURNS THERE IS OFTEN A LOUD BANG SOUNDS LIKE A BALL JOINT IS BAD. THEY FIRST TOLD ME IT WAS THE TIE ROD U BOLTS ON UPSIDE DOWN. CORRECTING DID NOT STOP THE LOUD BANG. THEY THEN TOLD ME IT WAS THE IFS AND THEY REPLACED A BELL CRANK ASSEMBLY IN IT. THE NOISE CONTINUED AND HAS BECOME MORE PRONOUNCED AND OCCURS MORE OFTEN AND IN LESS TURNING RADIUS. THEY HAVE TOLD ME THEY DO NOT KNOW WHAT THE CAUSE IS BUT THEY ARE SURE IT IS 100% SAFE SINCE IT HAS NOT YET...
