:shakeheadi have new tires and checked frontend parts for wear and cannot figure out why at 60mph and 70mph the whole frontend goes to shaking and bouncing?. i have new wheelbearings and frontend alignment done and wheels are balanced on my 88 gvl hatchback yugo. how do you fix this problem please.

Steering damper worn out? Or worn out CV joints (does the car make knocking or creaking sounds going around tight corners?).

My first guess would have been worn out shocks or unbalanced wheels.
