Hi. Was havin issues with power steering for a while and it turned out the high pressure line and return lines were likely leakin. Replaced them and that helped the issue significantly. But I'm still havin issues. When I turn at low speeds, like parking, there's a hard groaning sound and difficulty turnin my wheel. Any ideas on what could be wrong?

 

If you ran low on PS fluid you could have cavitated the pump and destroyed it.
