New LS400 owner here
I am also in the middle of a timing belt, water pump, cam/crank seals etc....except on my car everything is covered with an inch of grease/oil/dirt everywhere. It looks like the previous owner didn't care about not being able to see anything in the engine compartment. FML!!!!
Replacing the timing belt is easy, the hard part is cleaning everything before re-assembly............end rant

Ya ps pump is bad it'll work for like a day and a half if i limit my driving, but it leaks like a ***** so im done putting fluis in it to find the leak. Im just gonna get a new one when i have the money. As for the suspension, the car still has the air shocks. None of the corners have sunk since i bought it a few days ago, so im hesitant to just replace them with traditional suspension right now, id like to find out if the speed sensors are tied into the air suspension ecm and will cause it to malfunction as thats the codes i pulled from the height control light on the dash was a 31 and 35 which i found to be for malfunctioning speed sensors on the front left and right wheels. I wish i knew someone local to me with functional factory air suspension that i could test my switch and suspension ecm on.
Either way im ready to pull the air suspension once i get the traditional suspension from the junk yard, as my local one has 2 90 ls400s there. I'll be looking at around $130ish including cores and enviromental fees for all the corners

don't put standered suspension on, just fix the ishue with the air ride system. Or you can buy BC coils and put bags on them so you can sit hella low for show. And don't go to a Lexus dealer for ishues on a UCF10. Call around and look for a normal shop that has exp. with air ride and ask them for help.
where are the sensors i should be looking at located? Just in the wheel well or attached to the strut casing? Is anyone who replied to this thread in the portland, or area with working air suspension and can maybe stop by or meet up someplace to teach me a little about the chassis? I also have 2 extra cigarette lighters that work if anyones interested, i cant post in the classified section for a while 
Edit: who sells new bags and needed equipment for the ucf10s? If i do bag it, i dont want to use O.E. stuff i rather get new air tanks, pumps and other needed gear.

So i have a slight problem, my drivers side air bags are very slowly deflating. The car sat for about 3 months before i got it so i know that didnt help anything.
Im at a spot where i have to do cheap repairs, so ill be going with standard strut suspension.
