States broken front spring. I know these used torsion bars, so I'm thinking bad subframe? Don't know much about these cars, so I figured I'd ask and learn something new.

The torsion bars can break, like any other part. They aren't that hard to replace, although the price of aftermarket bars has gone up.

Might be a torsion bar mount that is broken, or the adjusting bolt.
