I finally replaced all my CV joints last summer (around 325K miles). I'd
been getting an odd clanking noise from the right rear which no one has been
able to locate. Decided that CVs were a possible suspect, so replaced all
four with used. Clunk is still there, but at least now I have peace of mind
knowing I have CVs with less than 100K on them. Replaced shocks and
bearings under same logic (Clunk still there).
