1994 H1 Steering Problem at stop

[southtexas]

I have a 1994 H1 and replaced the power steering pump because I get no boost/assist at a full stop. As soon as the truck is in motion the pump works well. I can hear the pump strain while at stopped like it is turned to the steering locked Right or left full position. The new pump did not fix the problem.

Any ideas?

How much air pressure is in your tires, this will drastically affect steering
at a stop, They still dont work good at a stop especially with the brakes applied as the braking is hydroboost using power steering pump for power brakes.

40 PSI and no foot on the brake.
