So the Fiesta ST has been handling badly recently. I replaced the bent rim, but the steering is still loose when turning right and the car tracks all over the road. I know that the ST’s have a desire to wander, but this is pretty bad.

No handling/suspension mods whatsoever.

Some theories from the forums are:

1) out of alignment from the bent rim
2) electric centre is off in the steering
3) Torque sensor issue
4) loose bolts on the steering rack
5) brake rotor issues
6) subframe out of alignment

Anyone else have any ideas? Any ST owners with similar experiences? I have 90,000kms on the car (56,000 miles). I really want to just get it fixed.
