Polyurethane Bushing Install
Before I get the car 100% put back together I am taking the time to address the weak C6 rubber bushing and installing the Energy Suspension control arm bushings and Prothane sway bar bushings....

Two questions:
What did you use to loosen the rear lower ball joint nut? Closed end wrench?
i didn’t follow why taking out the two lower pivot bolts let you not pull the drive axles.
And what is that awesome high lift hydraulic jack???

Mainly a street car, it may make it to Hallet a time or 2.
It did make the ride more firm. Biggest gain for me is it doesne't pull under boost now. Before it would dart to the left under boost. Little more NVH, but honestly the trans/motor mounts are the harshest. I am thinking about going back to stock.

I tried to illustrate with a cheesy picture. Basically grab an open end wrench and start unscrewing the ball joint nut until it wedges up against the axle. If you support the lower control arm and leave the spindle hanging in air the nut will force the ball joint to pop loose from the spindle and you can drop the control arm with out removing anything else. Pull the alignment bolts from the frame, shock bolt, sway bar, and the ball joint those are the only things holding the lower arm to the car.

Got it. Thanks for the super technical drawing as well! 
also, who makes that high lift jack (that is about 3-4’ tall) and what are they called??

I used this kit. It solves the issue with the rear upper bushing. https://www.corvettemods.com/C5-C6-C...xoC_9gQAvD_BwE

I got the hinson poly trans and motor mounts. They eliminated the drive train movement but the make the cabin resonate with certain engine rpm. I actual had to idel the engine at 720 to make it go away sitting at a light. idle at 650 was awful. I've only had them for about 250 miles so I'll update in a few more weeks when I get more miles on them.

So the Hinsion are more solid with less dampening, but still strange on that amount of noise transfer threw the mounts at low RPMS.

OEM are fluid filled to solve that problem to allow them to dampen better, but you end up with a lot of motor movement even before they crack to let all the fluid out.
