After weeks of trying to find the clunk in the front suspension of my leveled 21 TB and a visit to the shop still no answers. Then I came across this. After replacing these links the clunk is gone. One more thing, make sure the stabilizer is centered. Mine was shifted by 1/2 inch. I’m sure that’s part of the reason I could only hear the clunk on one side. I waited to post to ensure that was the issue.
