If there are already shops that sell replacements, this may be an issue to this steering rack. I don't know exactly the inner workings of this particular steering rack, but there are some with adjusters to take out the slack. I would highly recommend to mark each and every Bolt you disassemble and whilst reassembling it, tighten the bolts to those markings.
If the steering really would have encountered such a hard hit, it must be visible. Maybe the tie rod on the offending side is never than the other one? Is it bend?

This steering is assisted by an electric Motor? If it is hydraulic, you need to bleed the system before starting the car, otherwise it can damage the pump.
