I am new to Toyotas, so bare with me if this is a common question , I tried hunting around but couldnt find any leak quite like this. My power steering will sometimes not leak at all for 200 miles, then other times it will leak faster then i can add powersteering fluid while just idling in the driveway.

I cant figure out where its coming specifically because there is so much fluid caked on that part of the engine bay and chassis. It is definatly near or on the pump because the puddles are on the front passenger side of the engine bay.

Where would be a good place to start looking / is this kind of leak common on these rigs.

My truck is a 92, 3.0L, 4x4 with roughly 180k.

Pump is still working fine when there is fluid in it.

 

First problem is using powersteering fluid. With these trucks you HAVE to use Automatic transmission fluid in the power steering system. Powersteering fluid eats the seals and causes major leaks.

Most likely you need to rebuild or buy a new pump. The seals in the pump could be gone.

 

Hmm, I have been adding ATF, but judging by the bottles of Powersteering fluid i found under the seat the previous owner was not. Is the rebuild worth it (cost of parts + time to rebuild) or should i just get a new pump?

 

Does that go for a '94 FJ80 too? We might have been totally making our issue worse....

 

From everything I have read yes that goes for the FJ80 too, manual should call for ATF in a 1994 Landcruiser.

 

Hmmm, okay. Hubby got a reman. pump from Napa yesterday... said something about having to have a machine shop hydrolically take something off the old pump to install it on the new one?

From what Im reading it should be easier than that, yes? To install a new pump would we need any outside help (like a machine shop) for the 94' FJ80? Just wondering if he is going through extra effort that isnt needed...

 

Yes! My '95 LC does and Toyota still does this with their power steering systems (my 2003 Rav4 uses ATF instead of PSF.

 

I wasn't there, so I don't know what was said.

I can't say for sure for an FJ80, but on trucks the new (rebuilt) pump usually comes without the reservoir. That part is held by a bracket; once removed you just pull up on the reservoir (there is an oring, so pull gently).

On some trucks, there is an "idle up" valve on the bottom of the pump. (~75mm cylinder with two vacuum hoses). When there is pressure in the pump, it opens the idle up valve to raise the idle slightly. Otherwise you'd kill the engine when parallel parking. If your old pump had that, and the new one doesn't, take the new pump back. You don't really want to be transferring the old valve (so far as I can tell, the valve is plastic, and screwed into a tapered port, so cracking it is a possibility).

Last but not least, the new pump will not have the pulley. Once you remove the attachment bolt, you MIGHT have to pull hard to get it off. I was able to get it off with a big gear puller, but it's not really the correct application. And don't use the BFM; if you bend the pulley it will wobble and wear the belt quickly.

Have fun!

 

i run chevron rykon3 hydraulic fluid and have been for the last five years. it made the pump noise go away and is no longer leaking and steers easier when cold. its basically a hyd. pump anyways so give it the oil it wants ha ha

 

You should really check out ih8mud.com for LC info: http://forum.ih8mud.com/80-series-tech/

The PSP in an FZJ80 ('93-97) is crank gear driven. There is no pulley or belt.

Search around on 'Mud for lots of info.

 

Right - so he has to have a machine shop pull the drive gear off the old pump body and press it onto the new one...
