Shaking Steering Wheel '87 85/4000Q

[Jason Mawhinney]

I second the suggestion to check the control arm bushings.  If they're shot, they can feel like something is seriously out of balance when it is very slight.  Also, check to make sure the hubs where your hubcentric wheels mate up isn't damaged.  Mine was at one point and I went through wheels balance after wheel balance until I figured that out.  It was very frustrating!
Good luck finding the solution.

I'd check the "joints" again.  Check the ball joints, check the
control arm bushings, check the subframe bushings.  I once had a bad
ball joint / bushing problem that would cause the front of the car to
shake violently at 80mph, and that's what it was.
