    I took my 89 burb on a 90 mile trip through the Colockum Wildlife Area here in WA this weekend, not in 4wd alot but a lot of bowling ball sized rocks, ruts and the like. Did I mention dust? Anyway, coming home home on the highway I start to hear a chain draging sort of noise coming out of the t-case. (belive it's a 241) slow to a crawl and pop, the noise would stop. I noticed the front drive line was still turning in the parking lot. Ideas? Thanks!

    What is the position of the Tcase shifter? If it is indicating 2wd I would suspect a hub sticking in the locked position causing the Driveshaft to turn and subsequently the chain inside the case. Auto hubs are notorius for not working properly.

    You can twist the shaft by hand to make sure what you were seeing is just parasitic drag...they'll do that.

    Auto hubs? Need to back up to unlock them, but if it was in 2WD, that shouldn't make noise from the case.

    Thanks for the replies, it's making sense. Yea, I can turn the front shaft by hand...so it's just draging? shifter is in 2wd position. Auto hubs. Whats up with the clunk nearing a stop and then no drag noise? It's kinda scary..

    Are you sure that all of your tcase bolts are tight on the mount? There are 4 of them 2 on the mount and 2 from the mount to the tcase. Mine would clunk when my mount was loose and also my downshift from 2 to 1 is kinda stout also.
