Sweet, thank for the list!!

Also are the "Wheel Hub Adapters" the metal spacers for the hub on the wheels (all four) correct?

Kind of like this?

Also if I was to get some of these, what MM size should I get?

Here's a pic of my baby, might be able to give better advice based off of it

The front end shake is the caster arm bushings in the front, Change it to Daizen Front Caster Arm Bushings. Also change the Steering rack bushings to Daizen as well. My car is a 98 and i don't have any shaking problems at all now. I also changed my front lower ball joints. Very easy to replace.

Hey,

To date I replaced the front Upper Control Arms, Lower Control Arms No.2, Lower Ball Joints, Balanced all four tires & got my alignment done.

With that said the shakes are 50% better, but are still there

Anyone know the next step

If your on aftermarket wheels and dont have hubcentric rings, thats probably the biggest culprit.

Hi & thanks for the input

Are you talking about the adapter or just the rubber rings, cause I do not have the rings in the pic below installed?

Like These right?

Hi All,

Just wanted to post an update....

So I installed four of the Hub Centric rings on my rims & had all four tires balanced and I am absolutely amazed by the results.

My vibration problem is almost fixed, I would say it's about 90% gone!!!! Still a little vibe, but barely noticeable

Thank you all for the help, it means a lot

I hate to tell you this but my GS400 has has this problem since NEW right off the show room floor. The first owner took it in many times to complain and they never figured it out. I've since changed rims and had 3 different sets of tires on it. The only thing that helped hide it was my snow tires have very weak sidewalls and I don't get the shake when they are on the car.
