Constant Groaning sound from power steering

["Gil Thereault" <giln1oiw@xxxxxxxxxxx>]

  Hello to all. The most recent problem that I'm trying to correct is the 
groaning sound that is coming from the power steering pump.  Thinking it was 
time to rebuild it, I picked up the rebuild kit for the 86 535i for $35.  
After taking the unit apart, everything look well inside, No damaged parts 
or any unusual wear observed.  I replaced all the parts from the kit and put 
it back together.  I started the car and the groan still remains.  Same type 
of noise as before and the steering appears to operate as it should, easy as 
it did before. I took a look at the Bentley manual and then attempted to 
bleed the PS system as they described although the noise persists.

  Upon closer inspection, I noticed that the rubber hose with the cloth 
covering appeared to be partially collapsed and that the groaning noise 
(from the other all metal pipe) travels all the way to the pressure 
regulator.

  I have had this car for less then two years and love it.  One of the first 
things that I replaced was the nitrogen accumulator or the ball as the 
brakes petal was feeling a little odd.  This corrected the problem for quite 
a while but in the recent month or so I notice the odd brake petal feel 
again along the quick blip of the red brake light when depressing the brake 
petal.

  My question is, could this accumulator cause this problem with the power 
steering of could there be a problem with the pressure regulator which is 
shared with the power steering and the brake system.

  Thanks to all in the past who have helped.  I read nearly all the threads 
on this reflector.  Keep up your good work.
