Hey PTXer, you are one of the Guys that cleaned yours out per this Post:

I cleaned mine with a can and a half of brake and parts cleaner last winter. Squirting it in through the return (so goes the opposite way to dislodge all the gunk on the screen) and dumping it out the top. Dried it out with compressed air and reassembled and refilled. Noise gone. Be sure you recheck the fluid level a few times as the bubbles get worked out of the system. I didn't start up to drain as much fluid as I could out of the pump, but sounds like a good idea (although potentially messy).
