2004 CHEVROLET TRACKER Steering Problems

I purchased a vehicle from a friend that is 20 years old but runs great and he takes great care of his vehicles. This one was his away car, in that he was here only 6 months of the year and drove this one mainly when he was here and only put on about 2-3 thousand miles per year. He told me he was scraping the car so I offered him scrap value but little to my knowledge that the total frame is rotted from inside to out and on driving it home it thumped, shook rattled and scared the crap out of me. I had no idea being a car person all my life that this vehicle would be allowed on the road with only 84k on it it is undriveable and even a pro welder would not work on it.

DRIVING ON EXPRESSWAY CAR STARTED TO VIBRATE AND SHAKE SEVERELY. THE CAR WAS PULLING TO THE LEFT AND STEERING BECAME DIFFICULT, EXPERIENCING PARTIAL LOSS OF CONTROL. I PULLED OVER TO SHOULDER OF HIGHWAY AND UPON INVESTIGATION NOTICED THE CROSS BEAM WAS RUSTED THROUGH AND THE LEFT DRIVERS SIDE CONTROL ARM HAD BROKE FREE. I HAD THE CAR TOWED TO THE NEAREST CHEVROLET DEALER AND WAS TOLD THE VEHICLE WAS THREE MONTHS PAST THE EXTENDED COVERAGE. I HAD THE TRACKER CHECKED PREVIOUSLY FOR THIS PROBLEM WHEN I RECEIVED A LETTER FROM CHEVROLET ABOUT A POSSIBLE ISSUE AND WAS TOLD THERE WAS NOT AN ISSUE WITH MY CAR. REALLY! IF CHEVROLET KNEW THERE WAS A SAFETY ISSUE, IT SHOULD HAVE BEEN REPAIRED TO BEGIN WITH. *TR
