    I have a 1999 Yukon Denali I replaced the power steering pump due to a large loud noise I reuse the same Reservoir and lines and then I lost my power steering but was fixed by unclogging line and now the noise is louder and makes a weird grinding type noise when I turn, I had bled the lines refilled

    It really sounds like you still have air in it. It’s not leaking anywhere, right? Is the fluid foaming up?

    I’d try bleeding it again.

    if the clogged line caused it to run dry or aerated the oil you could have another burned pump. also with no flow it could have overheated the pump.
