- So the other day I noticed my Xterra was making noice, and I figured it was the powersteering pump. So today I went ahead and removed the belts because I figured it was my powersteering pump, but when I started it up the noice did not go away. I checked the oil and it's more then full, checked the heat shields for noice and everything seems fine. I'll post the video so you can hear what it looks like but any ideas or suggestions would be appreciated! My engine has a 143k miles and the horrible noice goes away after 3k rpm.
