Assume you've tried the obvious technique of applying rotation
to the ball joint while implementing the desired translation?

Of course. The socket is designed for tightness at the expense
of ease of movement.

And you want to defeat that design objective that keeps the device
stable under vibration.

Wrong assumption. You're assuming that making the joint easier to move
smoothly will necessarily cause it to change position under normal use. My
Focus does not vibrate, except on rough road.
