A couple weeks ago I posted an issue where I changed the fluid in my Nissan PS system and upon doing so i noticed very small bubbles circulating in the reservoir. Applied vacuum to the reservoir, no leaks, no odd noises and the steering worked like it should. Still trouble shooting the issue I noticed the fluid starting to get glittery, when i went to take a peek at the bottom of the reservoir there were small metal particles all over the bottom(brand new reservoir as well). I emptied the reservoir, cleaned it and filled it back up. Ran the car for another 5 minutes, next morning I check the reservoir and it's got a bunch of metal particles in the bottom again. Keep in mind I have not drove the car since, only let it run idle. I pulled the pump and took it apart but can't find any obvious sources of wearing. Any advice here? I'm quite certain the metal isn't from the rack, but is there anything else I should investigate before purchasing a new pump? Fluid used is Mobil D/M ATF. Thanks all
