common failure on the inner tie rod bushings causing the noise although it could be struts, links and many other items. go to a shop and have them check it for you and give them a bid.
This vehicle has two pattern failures that can cause the symptom you describe. The first failure is worn out inner tie rod end bushings and the other is worn frame bushings.
