Thread: ball joint maybe?

ball joint or cv halfshaft

From your description I was thinking of what moves when you turn. Strut bearings, the springs get pressures on them, ball joint, strut tower bar has pressure, endlinks flex, sway bars flex and cv's turn

At first I was thinking spring movement and strut bearings. But....this is a W body and therefore the sway bar coudl be breaking/broken as nearly all of them seem to do.

jack the front wheels off the ground

grab wheel at 12'oclock and 6 o'clock position

try and tilt the tire toward and away .. if there is play.. replace ball joints and go from there.
