PROBLEM STARTED TO BECOME APPARENT WHEN THE CAR BEGINS TO MOVE FROM A STOP. A CLUNKING SOUND WAS HEARD NEAR THE REAR RIGHT WHEEL OF THE VEHICLE. ISSUE BECAME MORE PROMINENT ON THE HIGHWAY. WHEN BRAKING AT SPEEDS OVER 40MPH THE REAR END WOULD WAVER AND THE CAR WOULD START TO FISHTAIL. THE PROBLEM WAS DETERMINED TO BE THE REAR SUBFRAME OF THE VEHICLE. THE SUBFRAME WAS COMPLETELY RUSTED WHERE IT IS CONNECTED TO A TORSION LINK. RUST WAS BAD ENOUGH THAT THE PART OF THE SUBFRAME CONNECTED TO THIS SUSPENSION LINK FAILED COMPLETELY AND BROKE AWAY FROM THE REST OF THE SUBFRAME. THIS IS A 9 YEAR OLD CAR AND THE PROBLEM OCCURRED AT 73,000 MILES.
