C4 shakes while driving
My 1989 corvette sometimes starts to shake while driving. The car drives perfect 97% of the time and like crap the other 3%. It feels like a tire is out of balance times ten. I have had two different sets of wheels and tires on the car, both balanced, and it does the same thing. Any thoughts?

When my front bearing went out, I felt a little movement. When I jacked the car up to check things out underneath and get the weight off the wheels, my front passenger tire would move a little bit.
Id check out your half shafts in back are solid, and all 4 bearings.

Tie rod end or ball joint is bad or going bad, I have the same problem, and I need to fix it, since I’m going to fix it myself I have put it off but it’s on the winter to do list, the tie-rod or ball joint will ride good sometimes than others it will vibrate at around 70mph, the vibration gets transmitted up the steering column, that is why the steering wheel shakes.
In my case who ever had the car before me over greased the ball joint and blew out the rubber boots and now when I grease them, grease comes out of the boot, which in turn caused the ball joint to deteriorate.

C4 Shake
The tires are new as well as the wheels, this was happening with my old wheels and tires too. I was hoping it would get fixed with the new tires. It is not a constant thing, just every now and then. When it happens it feels like the car is going to shake apart. I'll definately look at those ball joints

When I got mine, it shook REALLY bad. We put a new set of tires on it and it was doing what you described. Almost random. It turned out to be bad u-joints in the half shafts. It's perfect now.
Check it all out though. Every car is different.

If you've tried two sets of balanced wheels and tires, it has to be a suspension and / or wheel bearing issue. Check:
Tie rod ends, innner and outer
Wheel bearings
Shocks (usually overlooked diagnosing a shake)
Suspension bushings
Ball joints
Check shocks carefully. They are what controls spring movement, and if they're worn out, all sorts of odd things happen.
