Has the sound repeated since then?

Since last night no, as soon as it happened I threw her back in park and ran through reverse and neutral to drive again and it made the clunk again as soon as it went through reverse. Kept it in drive and just took her home. Hasn't done it since though. Somebody told me it is just the stress from the drive train to the trans and sometimes it just pops into gear.

Where you on a hill? Do you use the parking brake?

Doesn’t take much of a grade to make a snap noise; as first gear has nearly a 5:1 ratio
You also have a base w/open diff...so probably more play in the diff vs. a vlsd or aftermarket traction device.
