ghallam Posted December 30, 2004 Share Posted December 30, 2004 I need some Help.........I just got my '92 LS 400 this year, and I'm a novice at working on them. Recently, the steering column started squeaking, especially when cold. Now just today, the steering became very tight, as if there was very little power steering available. during lunch, i'm going to check out the fluid level. But what else should i check ? what are common failure items ? any help would be appreciated ! thanks !!!! Quote Link to comment Share on other sites More sharing options...

A mechanic recommended a Power steering treatment called Hapco which cured my problem. They have two Power Steering treatments and I purchased the one for fixing leaks. I believe that what it did was freed up the valve that becomes sticky and often needs replacement. MY problem has been solved for about 6 months. Good Luck.

kcpth Posted January 1, 2005 Share Posted January 1, 2005 check not only the fluid level... but in my opinion i would check the ground for some leaks... or look under the hood and see if there are any leaks or oil on hoses and stuff like that. You realli don't want the pump to be leaking cause it might leak on the Alternator... and then you'll have several problems on top of that.

UCF3 Posted January 1, 2005 Share Posted January 1, 2005 It sounds like your power steering pump is about to go bad. I'd think about buying a remanufacturered one. You can also do a quick search for power steering pump in the LS Forum. This will give you an idea on how much you're going to need to spend, and there are some links to a tutorial on how to accomplish this. If all else fails re-post and we can help you change the pump. If you want one from Lexus private message me and I'll help you get one below the retail cost. good luck Quote Link to comment Share on other sites More sharing options...
monarch Posted January 2, 2005 Share Posted January 2, 2005 what are common failure items ? ← Your power steering problems will never end unless these filters in the system are cleaned and kept clean: http://www.saber.net/~monarch/pscreen.JPG http://www.saber.net/~monarch/psclean.jpg For profit motivated reasons, many shops and mechanics would rather sell you a new power steering pump or steering rack instead of simply cleaning these filters out with brake cleaner. Search this forum using "power steering filter" and "solenoid filter" as your search words to get more detailed information. Quote Link to comment Share on other sites More sharing options...

99lsguy Posted January 4, 2005 Share Posted January 4, 2005 Monarch is referring to the Solenoid Screen (on the Rack)........it is cleaned with brake cleaner do a search and you'll find lots of info on this procedure..... & The screen within the PS Fluid Reservoir. I believe you remove the reservoir and flush with new Dex III and /or Brake cleaner...... Anyway, PS fluid should be flushed every 30K (in my book, every year) to keep the system clean.

AzHotLS Posted January 7, 2005 Share Posted January 7, 2005 Do the flush and solenoid screen clean. I just did mine. What a difference it made. Hey monarch, I don't know if it's just me but your links don't work for me. I'm real interested in seeing your photos. Quote Link to comment Share on other sites More sharing options...
