Still Vibrating after Road Force Balancing
Car still vibrates between 65 on up. However it is intermittent. Sometimes it will vibrate at 70. Sometimes smooth as silk
got the car road force balanced all wheels are between 6-7 lbs. I am going to go to the shop have them lift it up and check the lower ball joints and all the control arms.
QUESTION: Can i just replace a ball joint or do i have to replace the entire arm? Is the ball joint connected to the control arm in any way? Please excuse my ignorance. Thanks for your replies in my earlier post by the way.
If i don't respond in a timely manner its because after a while this site stops notifying me by email even though I subscribed to it.

Tire could have a bad belt inside, hard to pin point but should be seen when road force balancing.
If the rims is fine, most often it's the tire. Even a new tire can be bad when trying to balance it.
Also worn out suspension will have its hand too.

Rotate the tires front to rear now and drive it. This will rule out a slightly bent wheel or bad tire.

The reason I'm thinking ball joint is when the car was in the air we inspected the control arms and all of them had good NO cracked rubber around the joints. But on the left side when I hit a but it is noticeable clunkier
Also when I'm leaving the driveway if I turn the steering wheel almost locked left or right there is a clunk. But not when I'm driving. It's not the cv axles

If you have cracked rubber around the bushings, then that is a tall tell sign that the bushing are bad.
Air, water and dirt over time has made its way into the bushing, along with normal wear and tear and the bushing simply becomes no longer adequate.
Not many here have experienced bad ball joints, but many of us, including myself, have either bad CA's or have had to replace them.
If you actually watch the motion of the CA's and flex of the ball joints when the steering wheel is turned, it's clearly evident how they can go bad, especially given the weight of the car.
My guess is that you'll need at least all four UCA's replaced.

There is a member here, caha14, who used to own an 07 460L.
He had similar symptoms, and got Lexus corporate involved. From the outside, they appeared ok, but it was decided to remove them and they had a tremendous amount of play in them once pressure was applied while they were placed in a grip.
They were shot.
Typically, from reading symptoms other owners have described regarding clunking/popping noises, along with reading several LexusDriver maintenance history's, I'd still venture to say that your issue is control arm related.

I just had a road force balancing performed yesterday on my 2009 LS460 SWB with 39k miles. 6 control arms replaced up front in June 2015 at 34k miles. I was getting a very high frequency bouncing vibration between 60-80mph. When I get up to 90mph it goes away. Yesterday on my way to the balancing appt, my 4yo was in the back seat humming so he could hear his voice shake...then my 2yo chimed in. :/
I went to Firestone as they are one of the few non dealership shops that have Road Force balancing machines. The manager was really nice and answered all of my questions. After the balance, he said one of the front wheels was out of balance by 1/2 ounce. But the other tires were pretty good. And he said the rims were not bent and the tires were good too.
While driving home, the shimmy was still there so I'm in the same boat. I will say though that particular stretches of highway, especially the stretch I drive, are pretty bad and have grooves in them about every 10-12 feet so what I'm feeling might be that too.
I'm running Michelin Pilot Sport AS3 which have 15k miles on them. I have noticed they've becoming louder the last few thousand miles with a noticeable hum at highway speeds and I know the Pilot Sport are not the quietest in the Michelin lineup. And these tires usually go for about 25k-30k on our cars right? The tread looks like it's halfway gone, maybe a little more.
I'll be replacing the tires with the Primacy MXM4 or the Pirelli P7 when the time comes. I just want the quietest, smoothest ride possible.

What year and how many miles on your car. This should be in your signiture so you can be better advised. Like if I see you have 60k or up I can say probably control arms.
