power steering fluid freshen' up
We all know that Toyota and Lexus vehicles are notorious for bad power steering. Either the pumps, gear box or lines usually end up leaking, seals go bad or something.
Knowing this for a fact and knowing how much of a PITA this can be from my land cruiser, i decided to pop the cover on my power steering reservoir today and check the fluid. I wish i would have had my camera with me The fluid was black, almost like tar. It was horrible.
What i decided to do was use a large surenge (sp?) that is used to bleed brakes. It is clear so you can see the fluid you are pulling out. I pulled out 4 surenges of old fluid and replaced with 4 surenges of fresh Mobil 1 ATF. I did this several times over the weekend after driving and now the fluid is pretty clean.
I would advise you to take a look at your PS fluid and change if needed. Only took a few minutes of my time. The steering did seem noticeably smoother and the wheel was easier to turn. No groaning or buzzing and no air in the system.

You can bleed it out, but once air get's sucked down into the system it's really hard to get it out.
I just used that supersized surrenge to suck out from the reservoir and replace with new. Do it once a week and after a few weeks you will have changed out most of the fluid with new and no air in the system.
Or, you can do a complete flush, but that takes more time and introduces a much more likely hood of getting air into the system.

you will get some air into the system, just put the front up on jack stand and turn the wheel fully from side to side before starting the motor and letting the pump help. Be patient and you should be fine.
Not much of a way around it when you change hoses or pumps. With what i did i was just trying to keep it simple. On my land cruiser i tried doing the flush and got air in the system. It literally took me a month to get it all out. I had a groan in the system for almost a month.

Thats crazy, how did you get it out? Just by driving it eventually comes out, or did you have to do something else?
How do the dealerships bleed it when they replace pumps/racks?

Yes, eventually the air came out, but i had to put the front on jack stand 3 times in a month working the wheel from side to side to finally get it all out.
