My 2005 Pilot was making some rattling noises at the power steering pump, but the steering felt normal and fluid level was normal. I read about an O-ring on the low pressure side that is prone to failure and letting air into the system, so I replaced that and figured I'd change the fluid too. For this I used a quick method that I heard about where you just use a turkey baster to empty the reservoir and then turn the wheels from stop to stop with the engine off to get even more fluid out of the system. That seemed to work great and I got a lot of fluid out by repeating this several times. So I refilled with Honda genuine PS fluid, turned on the engine for a second or two and checked the reservoir to keep refilling as needed. After repeating this several times and turning the wheel full left to full right numerous times, I took it out for a 20 minute test drive. Now the noise is gone from the pump, but the wheel feels stiff compared to before I messed with it. The fluid level still looks good and isn't dropping any more, and I can see it circulating in the reservoir with the engine on. No bubbles or foaming. What am I missing? Why does it feel worse than before, even though the noises are gone now?
