Noisy Power Steering Pump

[rrgrassi]

I searched the forum for info on this issue, and could not find an answer...

This just started

Problem: In the morning, the power steering pump groans like it's low on fluid, when ever I turn the steeing wheel It goes away after the engine is warmed up.

The filter was changed last summer, and the level is with in normal range.

I'm wondering if I need to change the filter again and do a flush on the system.

Thanks!
