I recently purchased a 2004 2WD Yukon XL. Going around fixing a few items and came across the suspension part pictured below. They are up front right behind the shocks. I thought they were bump stops but some research in forums suggest they are called "Jounce Bumpers". Can someone confirm what these actually are and help me find a part number? I don't see them in any of the online parts diagrams. These are obviously shot and need to be replaced. Thanks!
