I am also having problems with my power steering. I have an '03 3500 4x4 SRW. Sometimes I get a whining noise when I turn the steering wheel from side to side, closer to the end of the turn. Sounded like it was low on fluid but it checked out okay. The last time that I noticed it was after returning from a camping trip with our trailer. It acted up in the driveway, later I noticed fluid on the ground. I dropped it off at the dealer today and they can't figure out where the fluid is coming from. They cleaned it up, put in some dye, and asked me to bring it back in 200 miles or so. The service writer and/or tech thought that it might be the start of the pump going out but didn't want to jump to that just yet since they are not sure where the fluid was coming from and they couldn't duplicate the whine. This concerns me since we are planning a trip to California from Colorado at the end of the month.
By the way, how much did your pump replacement cost and how many miles? Dodge headquarters could be getting a letter if it goes out after only 60,000 miles.
