OK once again I need the expertise of you wonderful people on the YJ forums. Unfortunately my Jeep has been off the road for the past couple years. I was just driving it home from the mechanics where much work was done to get it road worthy again. I was ecstatic my YJ was still among the living, but upon turning onto my street I heard a loud pop/grind noise come from underneath/behind me and then my 4WD light came on. I was at my house so I pulled in and got out to check it out. I couldn't see anything wrong, so I jumped back in, ran through 4WDHi, N, 4WDLo, and 2WD before leaving it in 2WD. This did not do anything for the problem however. The light remains on and the noise occurs every time I turn the wheel sharply. Your help is greatly needed as I am afraid dishing out any more cash for a mechanic is out of the question. Thanks!
