hmmm, in the 5+ years I have had my 88 I have noticed that side pops alot more when making turns. I never have had to do the axle U-joints, but they were on my list this winter when I was going to gear down my axles(looks like its gonna be sooner than later). I thought the disconnect was there to prevent this by disconnecting the axle while you turn. Well yesterday afternoon I was comming out of a stream and making a hard left when one of my friends thought he heard a ping come from my front end. I thought I felt some rubbing on the fenderwell and thought oh, if there is a problem it will make itself known soon; and it did a few miles down the trail I was looking at the pass. front u-joint. Everything up in there associated to the joint has a lot of play so looks like I get to do one as well.
