Just wondering if this issue could be a power steering pump problem (low pressure or low volume)
When I turn the steering wheel I can "feel" the valves in the steering box open, but I need to turn the wheel more before the tires start to move. It does not matter if I'm stopped or rolling down the road. It kinda feels / acts like the hydro-static steering on my tractor.
Background: Several years ago (maybe 2016), over the winter I rebuilt my leaking power steering pump and got a rebuilt steering box from Dave Lenzi. That box had issues but in the meantime DaveL got sick so I just put-up with that issue. After DaveL recovered I showed him the issue at a Rally and he agreed, so last summer I got a replacement steering box from him.
Now that Dave's wife is ill, I don't want to bother him with this, so I'm asking here first.
I'm wondering if there is low PS pump pressure or volume causing this issue. I do have a dual pulley system, so there is not a full wrap of the belt on the PS pump. I tightened the belts, but it didn't help. So I tried a make-shift strobe flashing on the pulley and it didn't seem like the it is slipping. I never have any belt squeal, nor any noise from the pump. I can't see any foaming in the fluid so I assume there is no air in the system.
I have KenH's electric wiper so no issues with the OEM hydraulic wiper causing problems. I also replaced the high and low pressure hoses when I rebuilt the pump.
The pump rebuild was pretty straight forward, but I could have messed something up. If I need to replace the pump, I think I'll just get a rebuilt unit rather than a rebuild kit.
What say yea?
