New (used steering rack). Sacrificial psfo

[igammie]

I just put a new, to me (used rack}. I put in cheap power steering fluid as I intend to flush the system and replace. I have to assume rack and my handiwork will produce contaminants.

 

How long should I wait before I change? I was thinking a month (I drive about 1,400 miles per month.

 

Thanks in advance!

 

If this is elsewhere and I missed it, sorry.
