[V8] Lumpy Power steering

[Mark Kalbskopf]

After my power steering became increasingly stiff, at lower speeds  
especially it seemed when slowing down for a tight turn or in a  
parking lot, and after I noticed the brake warning light flickering  
on, I ordered and installed a new pressure accumulator.
The pressure hose to the accumulator was weeping so I got Spokane  
House of Hose to fabricate me a new one (Highly recommend their  
service by the way).
The result of all this lying under the car, was that the brake  
warning light is now quiet but the power steering shows virtually no  
improvement.
It's kind of lumpy like there's pockets of resistance. I may be  
imagining it, but it might be worse when turning right.
There's no problem at higher speed but try slowing down for a sharp  
right turn from a cold start and you get a little work out.
(The steering rack was rebuilt about 25000 miles ago.)

Anyone, got some suggestions?  My daughter's driving the car mostly  
now and her definition of a muscle car is changing a little!

Mark.
