Paris Q

Bummer. Thanks for the reply.

I have a 1990 LS400 w 245,000 miles (bought new) and it still runs like a dream. Problem is the driver's seat spring/cushion support is shot and I get a serious back/hiney ache when I drive for more than an hour. I figure my options are to have the seat rebuilt (assuming I can find someone in the Central Mass area to do it) or to replace the seat. I'd rather not buy the same seat from a same-year junked LS400 as I may be buying another tired seat. Anyone know if later model LS400 seats will fit same tracks? If so, I'd switch out for a junked later model and possibly get a better seat. Any thoughts? Thanks in advance.

Is there a 1990 Lexus LS400 maintenance manual that one would recommend to see diagrams and schematics? I know there are different publishers of manuals and some do better with graphics than others. I'm specifically interested in the diagrams for the air lines and valves that feed the air suspension system. The rear of my car is settling uniformly and I suspect a leak in a valve or the compressor but don't know where to look. Thanks in advance.

Understand. Is this model/year prone to having a leaky line or valve and is there a particular location likely?

Forgive me for my ignorance, but what "lines" are you referring to? Are you saying it's possible to repair the leak as opposed to buying all new struts? Or is it not the struts that are the problem. That would be great. I'm not mechanically able to crawl under the car. Is this something a local mechanic can look for?

I have a 1990 LS400 with, I assume, bad rear struts. For the last four months or so the car has had a tendency to "deflate" and settle almost down into the rear wells. When I place the air ride control in the cabin from "Normal" to "HI", it raised the rear. I've had to keep it in the high position permanently until it now no longer works in high. Assuming my struts are shot, what are my options? A former Lexus service guy told me I was looking at about $800 each. Yikes! Am I stuck with Lexus parts? Do I have to replace the fronts, as well? Is it safe to drive it any distance with it riding as low as it is? I live in central Mass. in the country and am over 20 miles from a dealer. Thanks.
