How to analyze front suspension defects

[Tom in seattle]

When I drive over a road defect the left side (driver side if that makes a difference) feels solid and un-remarkable but driving over the same defect the right side exhibits a noticeable thump and rebound sound, loose parts or metal to metal sound.  I think I’ve eliminated exhaust pipes as a culprit and have replaced motor mounts.  I’ve lifted the front and tried to detect any wobble in the wheels….none.  How can I narrow this issue to bad suspension components or eliminate them from the chase?
