98 Camry Power Steering Issues

I have searched the forum, and didnt see this problem, sorry if I missed it someplace.....
98 Camry, V6. Power steering pump was leaking and level was low enough that it was groaning. I replaced the pump. 2 days later, more power steering fluid on the ground. Took some searching, but found it leaking from the boot on the rack. OK, very uncommon, but I replaced the rack and did a complete flush, refilled with ATF as recommended. every cold morning since, the pump will groan and steering will be very hard until it warms up... car will then drive normal. I thought maybe the pump had gone dry from the rack leaking and had gotten damaged... replaced the pump a second time... same symptoms!? belt is tight.. Im at a complete loss now... any thoughts?

Hi Brian,
Yes, air in the system had crossed my mind, but if that were true, the pump would groan all the time ( i would think). The car was parked in a warm shop over the weekend, and no groaning on startup... only when cold

What you say may not be true. I suggest you try the bleeding procedure in the article, if you already haven't. Notice that it is easy to trash the pump.
