I have a 1997 chevy suburban 4wd and while in 4wd it was making a loud clanging noise when accelerating in 4wd hi or 4wd lo. Anyways everything underneath was tight and no play. I couldn't figure it out. It has the dash 2wd 4wd hi and 4wd lo electric switch it wasn't flashing while in 4wd hi or low and you could hear an engagement sound when 4wd selected. I thought it maybe it was the front crown and pinion gear missing a tooth. I took it to the mechanic and it was the 4wd actuator! I guess it was gimped up and engaging and disengaging while in 4wd and making a horrible clanging noise. Anyways I replaced the actuator myself a few years ago (which was possibly the easiest repair ever) but the 4wd light was flashing and it wasn't engaging at that time. Anyways it cost me a fair bit more to have a mechanic diagnose and then replace the actuator but if it happens again I'll know what it is. Also I may be able to help someone else searching online for an answer. It's a fairly cheap fix to do yourself and super simple to do. About $60 from 1aauto! Hope this helps someone out.
