Yes, yamae is an amazing guy and a big toyota/lexus expert.

I took the fuse out, and ofcourse the light is off. Clearly i had the wrong fuse under the hood.

Yamae, thanks again!!

i didn't try, it is not difficult to pop the UBJ out and it makes the job no more difficult..

It is possible to do the front without pulling the upper ball joints. I've done it. car on the ground with jack stands.

I corrected the How-To to include the rear suspension as well as the info provided by Yamae for the Air-suspension.

I'm just assuming those are the main components that weigh the most. remove those and pull the fuse you should be fine. What ever air lines left on the car you can pull or just leave

As far as the air goes, you likely just need to bleed the system down, disconnect the lines to the bags, and remove the same way as the standard struts. Removing the additional components should not prove to be very difficult.

If someone can add in any detailed info and directions on how to do it, I will gladly add it to the how to.

I did the exact same things as shmee. Only need to disconnect 4 connectors and 4 airlines. I removed the upperball joints makes it a lot easier.

Just be sure that all the wheels are in the air. When you disconnect one airline the whole car comes down.

All the compressor parts are still in the car and i will leave it there.

Cool, thanks guys. Question for Dengman: how much different are coilovers from the air sus shocks? Is there some type of adaptor required for the top? Thanks.

Dont need adapters. I dont know how old you are, but i bought my coiloverset from a 40+ guy. And he hated the set! Its not a comfortable set, but really sporty.

LOL. Well, I am 40-something y.o. and I have driven VIP sedans since I was in my 20's and I lowered all of them except for a huge caddy I had back in the 90's. Now that you have the setup in your car...how do you feel it compares to the air ride? Maybe it's worth me going with a brand which allows more dampening levels so that you get the lowered stance w/o sacrificing ALL the comfort?

I will be leaving all the "guts" of the air sus in place...just in case.

From a comfy boat it changed into a HUGE go-kart. They are really hard, and i have the demping on medium. The springs are on the weakest set-up, and still very hard. The wheels also play a roll in this. I have 235/40 18 in front, 265/35 18 on the back. Not a lot of air left in the tires..

I Love it, before i could not take a corner without using the brakes. Now i can go as fast as the tires let me go, without the brakes gehehe.

Cool. Now don't laugh but I plan on keeping my 16" wheel setup! Why? Well, because no one does this and I am assuming (hate that word) that my ride won't be as stiff with a heavy car on coilovers AND skinny little tires. But, I could be wrong since this will be my first use of coilovers in any car...(used sport springs on everything else) 'cept for my '86 Soarer. I bought an air sus controller box for that - which worked great until the bag popped

I also have that air-sus controller thing (aftermarket) in my car, i still have to take it out haha. Its connected to the air-sus ECU with a lot of small wires.

Only never found out how it worked, i had no manual LOL. Once i was playing with it, i got the back down, en the front up.. And the other way around. The next day i bought the coilover-set , because the air-sus will never get that 'sporty' feeling.

I also whould like to have the original 16 or 17 inch wheels, but only for in the winter, with winter-tires. I havent got money now to get an extra set unfortunately. Sometimes it gets 10 degrees below 0 or more. Not very funny with those fat tyres...

Yeah, the controller I had was more user-friendly I guess. It had little pictures showing the wheels (front to back and side to side). Just push the buttons and it did its thing. Was totally cool, but at that point this car was already 12 years old (this was in 1998) and the air bags did not like all that inflating/deflating and one eventually popped. I was living in Japan at the time so should be easy to get replacement, right? Wrong! Toyota dealer wanted $1,000 per bag (parts only). Keep in mind this was before ebay when you either went to a dealer or the junkyard for parts. Ended up junking the car and getting a Crown. Ha ha.
