Stock power steering pump visual aid?

[TramCommon]

Hey guys, the ol’ girl has had a real weak and noisy power steering pump since I bought her in the summer.

Replacing/rebuilding the pump is on the agenda but I’m not sure if the pump currently on the vehicle is a stock Toyota oem part or a rebuilt aftermarket one... after all, this thing has close to 400,000 kms on it... it’s very possible this isn’t its first or second pump.

Are there any ways to visually determine with the pump on the vehicle if it’s stock or aftermarket?

Based on information read on these forums, most people recommend rebuilding a stock pump vs. putting in anything aftermarket. Anyone have any other thoughts on this? Are the aftermarket/rebuilt pumps THAT bad?

unless its a rebuilt unit that didn't use a Toyota core you may not be able to tell if its oe or aftermarket

I recently rebuilt the pump on my truck at around 194ish. I bought the nice OEM rebuild kit from wits end. As I was breaking the pump open to my absolute HORROR I discovered it was 100% chinesium. I rebuilt anyways because I needed to be back on the road and couldn’t wait. This is my first 80 so I don’t know what an OEM pump looks like externally but in-situ I’m not sure how you could tell. I figured it out once I found some internal markings (on the vane I think it was).

Fast forward 9 months and I am having groaning and weeping. I will be replacing with an OEM pump.

Are talking about a 3fe, or a 1 fz, or a diesel engine here?

Before rebuilding: replace low-pressure line, change fluid, replace cap. Run it for a while.

Also, a few capfuls of fabric softener could be added to the above list, before rebuilding.

Fabric softener is mostly water, so not a good idea. Silicone is a great anti foaming agent, so that’s a better option.
Case in point, when I wash my hands after working on fan clutches, there’s hardly any lather (I usually use dish soap) because the silicone is fighting the soap.

That said, I would work the problem. Does it cavitate all the time, or only sometimes? Better data is needed for any kind of diagnosis, whether that be via keyboard or in person.

She has a 1FZ in her.

Definitely something I will consider before replacing.

By "cavitate" do you mean only hard turning sometimes in some sections vs. all the time? If so... maybe? I think she's pretty rough almost all the time. There's nowhere in the full spectrum of her turn radius where she appears happy, haha.

She's also incredibly noisy. The sound of the pump whining when I fire her up is louder than the engine. Inside, when driving and when turning the steering wheel, it almost shakes it's so bad and the noise is incredible.

I'm completely willing to do as recommended above first before anything else:

"replace low-pressure line, change fluid, replace cap. Run it for a while."
