2011 Overland 230mm rear diff w/ ELSD - Help

Getting noise from the rear end when vehicle has sat for any number of hours. Rotational knocking only when accelerating and only for the first 5 minutes of driving in cold conditions.

Changed rear diff fluid but couldn't pull cover off to inspect as its frame mounted and not easy to do. No shards or filings but also no change in sound.

Read somewhere that they have clutch packs that have been known to make noise but I really don't know anything other than what I can find online. Asked the dealer about the clutch pack and was told that Id have to replace the whole rear diff with a replacement cost of $4500.

As it stands the noise is not too much of a concern but a possible inevitable cost like that definitely is. Can anyone provide some insight into rebuilding this diff if possible and part numbers. Or anywhere else this noise could be sourced? Rotational knocking from rear end, only on acceleration and only when cold for first 5 minutes of driving.
