Steering vibration and clicking on/off throttle

[Zygrene]

Can't figure out what's causing a metallic clicking sound when easing into 1st gear and going on or off throttle at low rpm. Also getting slight steering vibration and slight pulling to the right at freeway speeds. Bad vibration under heavy braking. Inspected front tie rods and control arm bushings and doesn't seem to be the wheel bearings as the wheels don't budge when I rock them. Any ideas? Was just aligned last week before Thunderhill.

Alignment settings on stock suspension:
Front: -1.2 camber, 8° caster, 1/8 inch total toe out
Rear: -2.0 camber, 1/8 inch total toe in
