please*HELP* ucf10 Power steering problem
SO HERES WHATS GOING ON..I have a 1990 Ls400, when I bought the car 4 months ago, it had a minor p/s leak. After the second month, the leak got worse, I was refilling it with the cheap STP p/s fluid about every 2 or 3 days. A friend recommended I use Lucas brand. This thicker fluid definitely did the job. I was refilling the fluid every other week. NOW this morning when I started my car, it made the usual "low p/s fluid noise" oddly enough, since I barely refilled it a couple days ago. But when I tried to turn the wheel to see how bad it was, No response at all. The system was completely out. then when I stepped outside I heard a bubbly noise. Looked under the car, and noticed it was throwing up power steering fluid under the driver side, but really foamy-like. Never seen it do that before. Then I checked out the p/s tank, and it was all foamy-like too. I turned off my car to let the pressures in the hoses settle..checked the tank again and it was nearly empty. I refilled it completely with more Lucas p/s fluid, turned on the car, and it began doing the same thing. It drained all the fluid. I need your help, Please reply with advise, tips, or diagnostics. Thank you for your time

Those stop leak products are and when the system is leaking that much, it needs to be fixed. With it leaking that much, the system isn't developing proper fluid pressure so there will be no power assist. Can be simple as a hose or something in the rack has gone bye-bye. Luckily it wasn't leaking from the pump or you'd have certainly killed the alternator.

You probably already know this, but it is essential to fix the PS leak ASAP.
The fluid will kill the alternator (directly below the PS pump), and will cost you more $$$ and hassle.

The OP says it is leaking on drivers side. So it wont ruin the alternator with his leak. Sounds to me it would be leaking from the solenoid (which is on the drivers side) or the steering rack itself. You will have to crawl under the car to see exactly where it's leaking from then we can let you know what it would take to fix it.

he needs to fix the PS leak ASAP regardless of where the leak is, and pump/reservoir/hoses are the common three areas - leak on the rack itself in LS400 is possible but much more rare.

my experience would say otherwise - it seems when an LS400 power steering system is leaking from anywhere, the leaked fluid seems to magically find the alternator and kill it!

my 96LS400 has a Power Steering Leak on the High Pressure Line with Part Number 44410-50050
Please provide me with a link where I can source this part at the most reasonable price.
Furthermore, I also have a leak on my Steering Rack. Would it be wise/economical to change this whole rack? or can repairs be done ?

here is a great deal on an aftermarket hose that has gotten good reviews here on Club Lexus and is dirt cheap - Enjoy!

Don't forget the power steering cooler pipe, the U shaped one that runs just in front of the bottom of the radiator along the front of the car.
This tends to rust due to it's exposed position and has been the cause of fluid loss in the past, it would also explain why the leak appears to be on the driver's side.
!0mm copper plumbing pipe can be shaped and used as a replacement.

I think I would just change the hose, which will end up being 95% of the leak, I predict
