Im not sure what your driving but my 92 teg does a very similair noise when i turn as well, and i thought easy, get my cv joint fixed but when i oped under, there wasn't a single tear, and they didn't have any give. each one has a good amount of life on them. i brought it to my mechanic for his opinoin and he came up with the same thing, he said basically if you want the noise gone we can replace them other wise they will work fine. never heard of this happenen before but thought i would throw in my 2 cents w/ hopes of saving you a couple bucks, but stilldefinatly get it looked at.
