Re: clicking noise, front drivers side.
Not sure if you're still having the issue but my jeep has had the issue since I bought it about a month ago. The bearings are fine and the cv's are fine but the clicking was happening only when there was a load on the drive train (revving in park or neutral, even while coasting, made no noise.) But the noise seems to get faster with rpm's and not necessarily speed, but again only when its in gear actually accelerating. I took mine to the dealer and they found the u-joint bolts were worn and backing out so they replaced them and most of the noise is gone. The remaining clicking under the same circumstances i'm starting to think may be the exhaust manifold.
