2002 Ford Focus drivetrain & axles problems

The rear end of the car started to wobble, loose control and fish tail at a driving speed 0f 70 to 75 MPH on a totally non slippery dry road. On wobbling, the car quit responding and started fish tailing eventually rolling over twice before it came to rest upside down down a hill. The police officer that investigated the crash site, looked into the tyre marks and verified that the brankes had been hit even before the car touched the fog line(wake up strip).

My 2002 ford focus se wagon has had innumerable problems. Firstly..melting battery cables due to poor and faulty wiring that could have caused an explosion of the battery had I not had to pay to get it fixed along with purchase of two new batteries thanks to the melting battery cables causing a short in the system. It subsequently killed the alternator which had to be replaced. It also subsequently killed the thermostat and the solenoid switch which caused overheating and dying problems with the car while driving.
