Do you have to replace the sub frame on your alero if the rack and pinion goes out?

No, you typically do not have to replace the subframe on a Chevrolet Alero if the rack and pinion goes out. The rack and pinion can usually be replaced independently of the subframe. However, it's essential to inspect the subframe and surrounding components for any damage during the repair process, as issues with the subframe could complicate or necessitate additional repairs. Always consult a professional mechanic for a thorough assessment.
