Would that make noise when tapping the brakes though? All the U joints I've replaced were identified by vibrating or a single clunk, not from small bumps.

We might not have the same problem, but it sounds very similar. I haven't replaced all the bump stop in the strut/shock assembly, but have replaced the tension arm, end links and both doughnut bump stops. The sound started on the drivers side only, but it is now very much on both sides. I ignored it for a while, but I will be actively chasing it this spring. Hopefully you can find the answer before I have to go through a bunch of parts lol.
