Any ideas??? since we cant know anything, here is a guess.... maybe your pump is getting weak, from age, sludge, restriction in lines, screen partially blocked, something like that, since higher rpms will bring it back. just a school of thought... I would do a LOT of cleaning.. cheers. bp Quote Link to comment Share on other sites More sharing options...
'95 LS400 Posted January 9, 2010 Author Share Posted January 9, 2010 Thanks. I am the 2nd owner and the filters were probably not cleaned. I have found a lot of threads on the power steering solenoid filters and will try to clean tomorrow if I can find all of the details on the procedure. Any recomendations?

90LS400Lexus Posted January 10, 2010 Share Posted January 10, 2010 As Billy mentioned and I did in another thread, it may be your rack solenoid. Speaking of Billy, he is the one that was able to get me a used solenoid for my 1991 LS off of a crashed 1994 LS. I had power steering nightmares on my LS for about 17 months. At first, there was no change when I replaced the solenoid last month, but I know it was good and mine was bad (mine didnt click when powered up). I then cleaned the power steering pump screen and still didnt help, but by a week later, my steering was 100% again and its not given me anymore problems. I am pretty sure it was my power steering rack solenoid. It had got to where I would get a shudder on low speed turns... then it would get to where my steering was stiff. Sometimes it would work for like 10 seconds after I first started it, then it would go away. Its all good now. I would replace the rack solenoid first before I replaced the entire rack.

I am not sure if the 1995-97 procedures are the same as the 1990-94 or not. I have not heard about as many power steering woes on the 1995 models. If its like the 1990-94, drain the reservior, remove three bolts on the reservior and hose and it pops off. Quote Link to comment Share on other sites More sharing options...
AzHotLS Posted January 10, 2010 Share Posted January 10, 2010 Recommendation? Yes, read this... http://www.clublexus.com/forums/ls400/3438...system-diy.html Doing the solenoid is relatively easy. 90LS400Lexus, rack solenoid, not reservoir screen.
