Do you know how to check the PS fluid level ?
If the level is good, try doing some figure 8's at slow speed in a parking lot, going lock to lock on the steering wheel. Do about 3 or 4 and see if that helps.
Last winter a few of us had a hard to steer when cold, issue. I did that fix and it worked. I had my rack replace 2 years ago.
