Yes, this it is always caused by a worn, loose or maladjusted suspension part. The hard part is that many time it is multiple parts that all contribute to the end result. On one of my vehicle I could not find it, finally found an old school tech, he lifted it up with wheels about a foot off the ground, put a 6ft 2x4 under the front tire and the leverage from that showed how badly the wheel bearings where worn even though by hand they felt fine and you could not wiggle the tire.
