Ive got new balljoints and tie rod ends on the way, if I don't want to fart around with having the daizen bushings pressed in should i just get new caster arms too?

Changed all bushings to Daizen, 3 wheel alignments, 3 sets of rims/tires, 12 RF balances, new ball joints/tie rods, new sway bar bushings, new rotors, no run out on hubs - still have 60mph vibrations on my steering wheel. $4k later. Nice car Toyota...

Did you check your steering rack at all? If it's loose it could be the cause.

I've had a slight vibration from 55-65mph for a while now. The other day I hit a pothole and blew a tire. Then I started hearing a knocking sound whenever I brake, and no it def had nothing to do with the brakes. I take the car to a mechanic and he points out that a few of my bushings are completely shot, especially the lca bushing. I just changed my 20" wheels for my stock 17's and been driving for about a week now. ALL VIBRATION IS GONE. and that is with shot bushings, also car rides super smooth, haha. I will be trying the daizens as I have another set of 20's on the way.
But I have to say, it was the wheels causing the vibration. Even with bad bushings car is smooth as silk.

Yeah the only time my car has really shaken is when my rims are bent. My car is a little shaky when I brake and if I'm going fast on the highway but I think that is because I need my wheels balanced.

Same issue here, my 19's need tires. Current wheels one is unbalanced/bent making a vibration at speed and under hard braking

Och

And thats really all it takes. Most people just dont want to admit to themselves that their 20's are bent, or that that their cheap aftermarket rims aren't properly centered, and will witch hunt the suspension, changing parts from good to new.

my steering rack was adjusted and is perfect. My car shakes with 16's and 18's and 20's so what you're saying about denial is irrelevant.

Och

Then your 16, 18, and 20s are either bent, not properly balanced, or not properly lug centric.

16's and 18's are Lexus wheels and therefore hub and lugcentric. 18's are brand new (second ). So all my wheels are bent or unbalanced during my dozen or so Hunter balances? Talk about denial..

You should find someone to swap rims with whos car doesn't have shakes - doesn't have to be a GS, can be LS/IS.

The only other thing that I can suggest is to find a shop that can perform lug centric balance.

Lug centric balance has been done. Thrice.

Och

Are you 100% sure they did lug centric balance? Are you using proper lugs?

I've suffered from the shakes in the past and they were all related to wheels only. With properly balanced wheels I was driving with no shakes even when my caster arms bushings were shot to the point where they were being held together by a miracle and my upper ball joints had tons of play.
