A question about an older vehicle with a king-pin style of front end geometry.
Is it reasonable to judge the wear on the king-pin & bearings by jacking the front end off the ground and vigorously trying to tilt the wheel in camber, while watching and listening for excess play?
I'm not asking for an exact test, just a distinction between "it's good enough for now" versus "it's really time to pull this whole thing apart."
