Strut mounts

The front end of my 98 VW Jetta (100K miles) makes a single “clunk” noise whenever I’m backing out of a parking space and turning hard right or left (occurs on both sides, though not at the same time). I had both front struts, strut mounts, bushings and bearings replaced, but the noise continued. I had another mechanic tear the whole thing apart and inspect it, but he couldn’t find anything physically wrong with the struts. It’s still making the “clunk”. Any ideas?

Could be a bad CV joint in one axle. In that case, replace both axles. It’s cheaper and safer in the long run than replacing just the joint.
