OK - so I replaced the pump, flushed the fluid and still having issues. Details -
01 DII 156k - PS pump making noise on right hand turns and when taxed (parking etc)
Replaced the pump a few months ago - all good, no noise but it has been cold (used LR fluid). So it recently got warm like 60's and 70's. Now pump is making noise again on right hand turns and binding. Pump was a reman unit but LR.
So what is the deal, is there a pump and fluid that will remain quiet year round or for the summer hot months should I thicken it up and for the winter thin it out - seems odd?
Guess it could still be the pump - fluid levels are perfect, no leaking and LR fluid. I don't get the right hand turn deal - that is usually the only time it makes noise, what causes that and why?
In my searching I read something about weak hoses that "suck" themselves shut and hence cut off fluid in a turn - seems like a stretch but that this point I am reaching for a solution - has anyone had this before?
I find it hard to believe with a 2 month old pump, fresh fluid, no leaks that when it gets warm it starts to act up.
Any suggestions welcomed - thanks -

I have a 99 D2 with 156000 miles,the power steering pump leaked when shut off,the resivoir always had foam,and it had the awful disco moan when you start it or turn. What I found was the "print-o-seal" gasket between the main body of the pump and the rear aluninum inlet housing was sucking air. To test; I removed the pump, lines, etc. plugged the outlet line,and applied 4psi to the inlet of the pump. The leak was easy to spot...To repair I removed what was left of the old gasket,litely sanded the surfaces with 360, cleaned the inside of the pump with brake clean until no oil was left as well as the rear housing. Assembled the pump with gray permatex "stiff" silicone. NOTE: The silicone fills a gap of .010", it must completely cure before use!!! Make sure you lock tight the four allen bolts also. When the silicone is cured fill the pump with PS fluid and rotate several times . Install the pump,clean the screen inside the resivoir,and fill with fluid. The pump on my 99 disco is now completely quiet !!!! no leaks !!! No foam!!! and it ony took a few seconds to blead out. Much better than $450.00 for a new pump. Works GREAT
