Suspension question.
Hi gang. Called dealer about the clunk when stepping into the car, and when crossing railroads and such, and was told no TSB from Lexus yet. Hmmmm, it sounds like it'll never be one. And don't want to let these people beat my car up for nothing; I went thru this crap on my GS400 and they never guessed the problem in 2 years (shimmy) until the TSB came out.
But the reason for this post is the following. Service manager said it most likely comes from the front struts' hydraulics (guy said our cars have struts and not shocks; what's the difference?). Then I asked if they could be swapped with the '05 ones, which are supposedly better. He said NO, unless all 4 were replaced, since they are COMPUTER CONTROLLED. If they'd just replace my struts with the same, why bother?
Unfortunately, I called right after finishing an oil change on my car; didn't have a chance to scrutinize this, but I'm almost sure there're no wires on our struts; otherwise we'd have the option to change suspension settings, and we don't.
Does anybody know if our car has indeed computerized struts? I'd like to take care of this problem, but want to understand what the cause could be. Thanks.

man what the hell was he smoking.... our cars are nice but it's not that advanced yet... the car has just the traditional springs/shocks system..... if it's something that advanced, how can most of us just swap to coilovers so easily. there is no computer control or whatsoever at all, i dont' see any wires connected to the springs/shocks system.....
but i think it does make sense to change all 4 suspension if you do, coz' it's more about balance imho
but i probably wouldn't trust much from what that service manager said....
the soarer in japan, however, does have the option of air suspension i believe, and that would be more complicated i suppose

Hey Rominl, thanks man. That's what I thought. All the cars I've seen with electronic shock control have the wires coming out from the top of the shocks, inside the hood (to keep water out). I'll call the manager and tell him he's full of it.
I still wish there was a fix for that clunk though. I refuse to let thos clowns drive the crap out of my car just to tell me they don't know what's wrong.
Do any of you have that problem corrected? I don't mind the slight clunking when stepping in, but it sounds bad when getting over a pot hole of a bump. And it doesn't have to be that big to happen. Thanks

no problem man, i am just sharing my 2 cents of comments. i have to admit i have bad ears. with the stock suspension i never heard any noice when going over bump or so. is this with the window up or down? seems like it's pretty loud?
now i have coilover of course i dont' hear anything.

Yes, I can hear it with the top and windows up, and even the stereo playing (not overly loud though). It's definitely not something loose on the suspension because there's zero noise over normal road imperfections. I'm almost certain it's the shocks.
Talked to the only dealer in town, and the 2nd service manager in a few months is gone AGAIN. The highest 'authority' was a service advisor that didn't know crap. I guess I'll have to wait a few more weeks or months again.
Maybe I can give a call to Lexus corporate? Where can I find the right number to call? Thanks.

if it's something that loud then it's definitely something they need to look into

Sorry for the delay. Yes Joe, I still have the run-craps, and will continue with them for a while; car only has 2,500 miles; don't want to throw new tires away. At any rate, car shouldn't have clunking sounds regardless of tires. Will follow Rominj's advice and call Lexus corporate next week. I think the 'clunk-when-you-step-in' is related to the one on potholes; I probably just have it worse than others. I'll let you know what Lexus has to say on this issue; they better not say they don't know about it, because the ex-service manager said he touched base with them, and they acknowledged the problem but not a solution. This was over a year ago. Have a nice weekend.

I have a similar problem with my 2002 in that there is a "clunking" noise when I turn the wheel and step on the brakes, but ONLY when cold. For instance, I hear the noise from the front wheel area when leaving my garage in the morning at the bottom of the driveway which curves and is sloping down, but nothing after it is warmed up. It seems like it has something to do with the first time I step on the brakes, but I don't see or feel any problems with the brakes. If anyone has heard of this or has any ideas, I'd be very grateful.
I did have a creaking noise in my previous SC300 over large and gradual bumps when it was cold which I endured for years. It turned out to be the sway bar bushings, and I wish I had replaced them much sooner!

Interesting discovery Bubba; will pay attention to see if my car follows the same pattern. I think it will, since the step-in-the-morning clunk only happens the first time I use the car. The other day I wasn't paying attention, but I'm almost sure I heard it from the rear this time.
Does anybody know if the shocks are the same all around, or different front and rear? Maybe it's the same kind of shock but different lenghts. Rominl? Any other suspension expert?

if that's the clunk sound you talk about, that's the brake pad shifting when cold. i know it's sorta common on the gs
