What is recommendation regarding play in rack and pinion?

What is your question?

Sienna 2002, 113k During alignment, tech reported to me that I had play in right front rack and pinion. Quoted me $ 800-1,000. Not noticeable at that time when driving. Said would eventually notice looseness in steering. Have put on 3,500k since with no noticeable looseness. Keep an eye on it or replace soon?
