All, I have a 2007 Silverado classic 1500 with 90K miles.  It has a whine/groan in the power steering pump that is worse at cold temp.  Steering is fine.  The fluid is a little dark, but doesn’t look that bad.  I was considering flushing and replacing with a synthetic.  Just wondering if that will quiet it down or am I looking at a new pump?  Thanks in advance!

Put Redline power steering fluid in it.  If it can be quieted, that will do it.  If that doesn't work, you probably need a new pump.
