Daizen Bushing Noise?
On my 2002 SC430, I had Daizen sway bars installed around Jun '04. Several months afterwards, I noticed squeaking noise coming from the polyurethane bushing during suspension rebound mostly. Not really during cornering. Finally in Oct '05, I worked with Sewell Lexus (Dallas, TX) to have the bushing relubed to make sure they were done properly (they didn't do the initial install). Then around Feb'06 the squeak came back. I notice it more when the weather is colder or in damp conditions. Has anyone else had this issue? Thanks.

I havent had those issues yet but sounds like a grease issue. It could be at other spots not just where the sway bars come in contact though. Could be at some other suspension parts.

Squeeking is the biggest complaint from any polyurethane bushings! They will never touch my car. Nothing worst than driving around in a luxory car that squeeks!

We really (really) don't have a wet environment in N. Tex, especially this year. ]
I think that the interference point between the bushing and the bar is on the front sway bar where the outboard portion of the bar curves and exits the bushing.
I can have them relubed, but it requires disassemble/reassemle, and that's a pain even if someone else does it.
The answer to the ride question - YES, it's a much better ride - not sports car flat in a turn, but a marked improvement. Also dump the run flats if you haven't. Get the Vette Z06 flat tire inflater bottle and a good inflation pump (I burned a cheap one up) that runs off the battery. All store nicely under the trunk floor mat.
Anyway - thanks for the replies - I seem to be the only one with the problem now.

Rominl - thanks for the help. I've heard only good things about Daizen from everyone. I'm beginning to wonder if I have that one front bar that has the bend that's just a little out of spec, and causing interference on the outboard portion of the bend and the bushing. I'm communicating with Sewell now, fyi. After thinking about it, this is the only conclusion that I can come up with. I remembered that last Oct one of the Sewell tech guys said he thought there was a design flaw in the bars because the bend wasn't located exactly right. Maybe it's just mine being out of spec a little(?).
Thanks
Thanks

I've had the same problem -- squeaky front bushings, particularly during drastic temperature or humidity changes. I also take my car to Sewell, but I didn't have them regrease the bushings.
I intend to ask Todd about this, but I'm curious if we can grease the bushings ourselves. I have my doubts that WD40's spray lithium grease, while easy to apply, doesn't contain something that may deteriorate them.
I do recommend keeping them lubricated. While I love my sway bars, I believe I have a new issue, now with the front one. I won't go into details until I talk to Todd, but the last update I got was that the bushings could be worn.
The old issue is here.

i would definitely suggest against wd40. i think it does more harm than good in removing the already present grease
i talked to todd before, he said you should only use the grease that comes with the daizen bushings / sways. they are one of the best he has used so far and he's been pretty happy
