Chad:
I am knowledgable about the 1995 LS400 P/S system and there may be significant differences between yours and mine, so treat what I have to say accordingly.
You didn't elaborate much on what My power steering has gone out really means. If you could offer some more details, it will help others help you.
There are two valves of interest in the P/S system. The first is the ACV, or Air Control Valve. It is black plastic, has two hose barbs on it and mounts on the lower, outboard side of the P/S pump. The first hose goes to the downstream side of the MAF (Mass Airflow Sensor) and the second hose goes to the airchamber/intake manifold. It is usually this valve that packs it in before anything else.
The second valve is the FCV (Flow Control Valve). It is inside the Pressure Port Union that screws into the bottom outboard side of the P/S pump. The Pressure Port Union is the threaded piece that the high pressure (Metal) P/S hose connects to. I very seriously doubt that there is anything wrong with this valve.
If you get a hold of a new or re-manufactured P/S pump, the flow control valve comes with it (installed inside of the pump). The ACV valve needs to be purchased as a seperate item and I'd recommend that you install a new one with a new/re-man pump.
Now, onto one of my "favorite" subjects; The P/S Rack Solenoid Filter. I'm not going to wear the tips of my fingers to stubs re-typing information from previous posts. Please do a search for Solenoid filter, etc. Also, start at this post; http://us.lexusownersclub.com/forums/index...ndpost&p=166483
You will see a number of different opinions, but generally, I think everyone arrives at pretty much the same conclusion. That is, the filter on the Rack Solenoid needs to be removed and cleaned periodically.
Thank you!
Does your advice hold true if I tell you that I have lost no power steering fluid?
My DISH also went out (they learned I was picking it up from Mexico), so the weather is great, but no TV.

Some other advice that you may find helpful:
I found a master mechanic from Canada
DO NOT buy him or otherwise offer him a "3.2" Beer.
DO NOT mention Canada, Hockey, or the Olympics in the same sentence. They're real "touchy" about a "little game" that "didn't exactly go their way" today. I work up there & I'm layin' low for a while.......

By power steering went out, I mean I was pulling into a parking spot and one of my passengers said they heard something "pop". I didn't hear anything but when we came out I simply had no power steering. I checked the level the next day and found it to be full.
Ajijic has narrow, cobblestone streets and small parking places. I have really given my power steering a work out. Also had some work done on the P/S a few years ago--I believe I had the pump replaced.
