Gen 1 GS300 Sport Power Steering Issue

[Am123]

Hi Everyone,

 

I'm somewhat new here, so forgive me if I have posted this in the wrong section. Also I am incredibly useless with the mechanical stuff. Simple stuff I can do.

So here's the problem, a week ago my car developed a horrible whine from the power steering pump, I was advised to drain the fluid as it looks like the previous owner either used the wrong kind or it's just old? Either way the fluid was not low but it was pitch black.

I drained the fluid out and filled with fresh atf, and repeated 3 times, turning the wheel lock to lock in between changes, until I couldn't see any of the old fluid anymore.

The whine has quietened down a bit but I can definitely still hear it. I wanted to know if anyone has any experience with this? Will the whine eventually go away or am I missing something?

The power steering feels fine btw, it did have a slight vibration coming through and a strange almost burning like smell but since changing the fluid both of those issues have gone away.

I'm a bit lost here, so any help would be much appreciated.

 

Thanks everyone

Certainly sounds like the pump is goosed. If it is worn, that could explain the black fluid, rather than lack of maintenance being the cause. If it goes black again quite quickly, it's a dead cert the pump needs changing.

Thanks mate. I think it is the pump. Now I need to find out how to replace it 😋

Scratch that. Started it up this morning and no whine. Checked the fluid and it's not black anymore. Maybe just needed to get fluid through the system properly?

Might flush the system again just to be sure.

That's a stroke of luck then. Fingers crossed.
