Air Suspension 2004 Ls430

[Jake430]

Has anyone changed their air suspension to standard shocks and coils. Second front unit gone in 100k. Thanks .

hi

havent heard of anybody doing it - who has diagnosed the fault? - sometimes it could you be the sensors which get water ingressed and start playing up?

Local garage. 65% imbalance between front units. We tried standard, high and sport settings.

I forgot to say that the problem is with the damper not the air bag.

Have a dig around on the american owners club forum, I'm sure there was a link posted on one of the 430 suspension problem threads.

I researched this a while back as I plan on keeping my LS a long time but don't fancy £1k+ a corner suspension replacement. You basically have two options, either use OEM Lexus LS430/Toyota Celsior shocks/springs which will cost you about half as much as air shocks per corner, or buy a set of LS430 coilovers like the BC racing or Tein ones. In either case you simply swap out the air shocks for the spring ones, rmeove the fuse for the air compressor, and all's done (the car will forever think its in high mode however, but no VSC problems). From what I have read the aftermarket shocks can have their dampening adjusted between Lexus GS/BMW 5 series softness (so firmer than a LS430 as standard) down to iron girder hardness, the standard LS430 spring/shocks feel like a spring/shock LS400.

Thanks for your reply James. I am waiting for Strutmaster to get back to me. I wonder if shocks and coils from a 00-03 will fit in a 04.

As far as I know all LS430 years use the same sets of spring or air shocks, it didn't change again until the LS460.

Rang my Lexus dealer, you are correct all 430 shocks are interchangeable. To change from air to standard requires extra fittings. Total cost for parts only about €2,500.00. Air shock only about €1,000.00 each. Strutmasters are checking shipping costs.
