I have a dana 30 front with a trutrac locker. 2 years old, but has started to "stay engaged" recently. Won't kick out on the straight away, and vibrations on the hiway. I ususally keep it in part time for the winter, this year it started out with a bad clunk as I turned sharply from the driveway and did it a few more times since. I put it in 2wd for now, but when I tried it again it does the same thing.
Anyone got any ideas? THX
