530CK power steering problems

What I have done so far is rebuild the power steering pump (did that while rebuilding the engine), replace the steering cylinder gland and piston seals, and replaced the manual steering pump shaft seals.

The last thing I did was the steering cylinder rebuilds. The symptoms prior to rebuilding the cylinders was always having to turn the steering wheel to the right to keep going in a straight line along with using both arms to make it turn.

All thats left is the steering control valve and the insides of the manual steering pump. I'm trying to figure out which to tackle first.

With the engine turned off the manual pump does turn the wheels, not very easily but it does turn them which makes me think the manual pump is probably ok, or at least in reasonable condition.

The last symptom is you can feel a pulsating while holding the steering wheel which makes me wonder if the shuttle in the steering control valve isn't bouncing back and forth.

Any thoughts or suggestions as to what the problem really is?!!!

Thanks,

I'm not sure pulsating is really the best way to describe it although if it is the pressure relief valve it could be a symptom of it opening and closing slightly, possibly indicating a bad spring. The parts catalog doesn't show a breakdown of the relief valve but maybe its something I can clean out.

I'll check it out in the next day or so.

Thanks for the suggestion.
