Need some help / Hydraulic P.S.

Parking lot maneuver, turning the steering wheel 2/3 to 7/8 to the lock I lose power assist. It can be turned to the lock, just NO assist. Had it to the dealer under extended warranty diagnosed as bad steering gear. They replaced it, I picked it up tonight and there is no difference. Anyone with hydraulic steering experience this? Is this normal?

Thanks in advance for any input!
