Rack and pinion

[SlayerE]

I have a 2003 Pontiac Grand Am the front end was struck while driving cracked rack and pinion only 2 Days Later did rack and pinion fully break has not been drove since removed rack and pinion do I still need to flush system before installing new rack and pinion?

My opinion would be to flush the system, for two reasons:

1. It's a 2003 GA, I doubt previous owners have ever flushed it, so now is a good time to clean it out and start with fresh power steering fluid, especially with a new rack. Why contaminate it with junk to begin with?

2. Flushing and adding new fluid will allow you to bleed the system and get rid of any trapped air that the either new rack or power steering hoses may have in them.
