Hey guys, so I currently own a 1990 SR swapped hatch. The power steering is acting odd because it feels like it kicks in and becomes hyper-sensitive at 3k RPMs and which point it also whines like crazy. Any lower than 3k it feels mostly fine except when moving very slow it almost feels like it isn't on at all. If I rev it a little you can feel the steering get better.

It feels like as the RPMs increase, the pump functions more. Up to the point where it feels like its over functioning and the steering is too light and sensitive. When it "kicks on" at 3 it whines. It will continue to whine until the RPMs drop back down.

I'm assuming new pump but I'd like to verify before buying one. Thanks.
