Any GM vehicle - with a ‘conventional’ - 10 or 12 bolt (closed axle differential) - will do the same thing - that’s just axle end play.

IF these vehicles are shoved back and forth hard enough at the rear - with tires on the ground - you WILL hear the axle shafts bump the center spider gear pin - located inside the differential.

IF this noise you are hearing is obviously something other than axle shaft end bump - highly recommend visiting local auto repair facility for hands-on testing.

Here is a link to some ‘very interesting’ reading on this subject:

In this article - the person mentions leaf springs as the culprit - you can judge for yourself.

Good luck with it!
