#201 of 2081 Service manual , power steering fluid change
Apr 25, 2001 (3:38 am)
Q45man, thank you for your many informative posts.
I am interested in purchasing the manual's for my 1992 LS 400. Where can I purchase them? Lexus or after market, please advise. I agree these books are very important to owners of older units.
Also please tell me how often, or when the power steering fluid should be changed? I did not know this was the cause of the pump failure. I wonder if there is a way to change or clean the filter as you mentioned it get's "Full of crud" or by changing the fluid regularly the crud does not build up. Can I change the P/steer fluid myself? is it difficult?
I also have the popping or cracking noises coming from the from brakes. I was considering new fitting kit - shims, rotors and pads. Can I just replace pads & fitting kit with turning rotors? (SAVE THE COST OF NEW ROTORS). When I press brake pedal now I feel a vibration in steering wheel, something is out of round and only felt when applying brakes from speeds above 25 MPH.
I also have the transmission shudder when downshifting (Tourqe converter?). In earlier posts I saw a suggestion to flush and change fluid to type IV and replace screen. In your experience does this solve the problem?
Best regards, and thanks again for your input.
#202 of 2081 1992 LS400 idle and transmission info
Apr 25, 2001 (5:38 am)
I have a 1992 LS400 with 123kmi.
The cold idle is 1.3k at 45 degree ambient for those interested. Only a modest surge when putting into gear. I never warm up the car for more than a minute...I just try to drive easy for the first few minutes to let her warm up.
I also had the transmission shudder and changing the transmission fluid fixed it....I did not use the new type IV but did have the entire amount of fluid changed i.e. not just removing the plug and draining it. This was done at a local shop and not at the Lexus dealer...total cost $70.
Thanks for all the info from everyone ...My LS400 is the best car I've ever owned!
#203 of 2081 Trans flush
Apr 25, 2001 (7:30 am)
Hi mhartless they might have used DEX III for your flush on your trans, this could destroy your transmission you should have only T-IV put in it cost more, but not as much as a trans As to manuals I bought mine from Irontoad.com not cheap 160.00. As far a the steering stuff goes I suck the fuild out of the pump from on top and refill about 4 times driving in between fills, I do this once a year on all my cars,I use a vacuum pump but you could use a turkey baster,you could pull the return line off and crank the engine, I buy the Valvoline synthetic, the fiters are not easy, one is in the control valve on the rack, not fun to get at, the other one is in the filler neck on the pump, dont use a carbon based cleaner to clean them it will melt the plastic screen.
#204 of 2081 Thank you Transmission and P/Steering advice

Thank you both for the resposnes. Great information and advice. I think I will pass on cleaning power steering filters altogether and just replace fluid often!.

#206 of 2081 P/S Pump & Ball Joints
Apr 25, 2001 (5:54 pm)
I have a 1995 LS400 with 109K, Went to the dealership to get basic oil change, was informed that I needed the dreaded P/S Pump replaced and pair of ball joints, total together $1400 (850 p/s, 550 ball joints). My question is should I stay with the dealership or try an independent mechanic. never took anywhere but to the dealership, what should I look out for if letting anyone other than Lexus touch the car.
All and all I love my Lexus.
One other dreadful thing happen, parked the car by itself as always, came outside looked at the Lexus,lo and behold someone hit the the lower quarter panel with their bumper and just drove off (boy what a day I was having). Smashed in the quarter panel about the size of a golf ball.
Do you guys recommend someone other than a collision shop to fix golf ball size dents.
Sorry for the long post just had to vent.

Apr 26, 2001 (7:27 am)
Hi Your only second choice on the power steering pump is to ask your dealer to put in a reseal kit or have your local service guy buy the kit from lexus and see if he will put it in, depending on the condition of the pump this can be a good thing or a bad thing with that low of miles if the seal is installed right it should work out well, as far as the ball joints anyone can put a set in I would look for a frame and alignment shop.
Good Luck and let us know.
#208 of 2081 1995 LS400 CD LCD
Apr 26, 2001 (10:52 am)
I'm just now purchasing my first LS400 -- and the first shock seems to be that the bulb on the CD display is out, so you can't see it at night.
The dealer has indicated that you can't change the bulb -- that you have to replace the entire $600 unit.
First, that sounds like mighty questionable manufacturing, to have to replace an entire radio to fix a $1.50 bulb. (unless, of course, you're the guy that can charge the $600!).
Any suggestions for how to get this fixed without that much outlay?
#209 of 2081 92 LS400 AC System Replacement Tip
Apr 26, 2001 (12:45 pm)
Thanks to all the previous contributors on this subject, especially to those who advised not to have Lexus do this job. My 92 (220K km / 140K miles) lost refrigerant through a leak in the evaporator and subsequently fried the compressor. I also needed to change to the new refrigerant. A very good AC shop in Toronto had a source of well-backed re-manufactured compressors and was clever enough to fit a new evaporator for a Toyota Cressida instead of the Lexus part. Same fittings, just a tiny bit narrower & less than half the cost. The whole job including the conversion to new refrigerant still cost more than air conditioning my house a while back but was done for less than the cost of a new compressor from Lexus. The shop is also backing it as well or better than the dealer.

Please add your car's data to the list. Does anyone's car NOT idle fast when cold?
