My current issue since my purchase 2 weeks ago 4 Runner Limited TRD Supercharger I have replaced the rims tires and all the ball joints.

When I am on the hwy and approach 60 MPH the trucks starts to shimmy from left to right back and forth increasing to the point of a death wobble. Weird part is the steering wheel stays straight and has no vibration or wobbling.
I am thinking the sticks are blown out any insight would be appreciated.

I had that start happening on mine a few years ago. It wouldn't automatically start up at higher speeds, but sometimes after a road heave or bump, it would start a slow back and forth swerving motion. I would brace my leg against the steering wheel to make sure I wasn't subconsciously contributing to it.

It ended up being a loose/worn panhard rod bushing on the rear suspension. I finally found it by shaking the car hard side to side with it parked and watching for deflection in the bushings.

Either that or broken/worn rear link bars.

When sitting still, the bushings are often under a fair amount of strain and won't easily wiggle around, even if they're worn and loose. You might need to really shake the car around to see what's loose.
