My TJ Wrangler 2.4, 2004, NV1500, NP231J. Lift 2". Diff 4.88. Tapping, rattling under the car. Tumbling, rattling when climbing and heavy loads. On the video can be seen the rattling. Could this be the transfer case chain or in something else to look for the problem?

It sure sounds like a transfer chain slipping. Possible driveshaft, but probably the transfer. Be sure everything is tight underneath. Trans to transfer. Trans mount, motor mount. But be prepared to pull the transfer out.

I have ARB air locks on the rear and front differentials. They are new, I believe it is not of the differentials. My colleagues here have suggested that the chain is rattling.
