Jim and samslam, have you checked the axle bearings? Or the ring and pinion for alignment issues? Maybe a loose U-joint? Or a U-joint cap missing a needle bearing or two. Double check the rear shocks, leaf springs, etc. Make sure you aren't experiencing a tread sep issue, or a tire cupping issue.

Jim and samslam, did you guys every find out the problem with the vibration? I have the same issue. It gets worse when the weather gets colder.

Ctuba, have you had it in a shop and had them pull ALL codes, both hard AND soft? Soft codes don't cause any of the lights to come on, but can reveal problems.

Hi Guys
I had a similar problem with an SC400 and it turned out to be the type of ATF that had been used in the transmissio. You must use Toyota Genuine ATF Type IV to ensure that the vibrations are removed. If you've used Dexron or similar you may need to change it a couple/few times to remove any trace of it.
Best of luck.

Thanks for the heads up there Smokey. Hopefully the guys having the problems will see your update.

I had a similar experience with an SC400 1994 model. After a lot of testing etc I found that the use of Dexron automatic transmission fluid was the culprit. Toyota/Lexus have specified a particular type of fluid and that only can be used. Try changing the fluid with Type IV from your local dealer, drive it for a while then change it again to try to get as much of the Dexron out of the system. It worked for me.
