Dummy me just noticed yesterday while driving, that taking off from a stop, the 4wd selector gear shift on the floor moves back a little and then relaxes back to original position,,, does it on every shift also, just more noticeable on take off, probably nothing, just slack wrapping up from torque,,,

But does anybody elses do this?

 

Normal. Even on gas trucks.

 

Mine has done it since birth. Just the engine and tranny moving on the mounts.

 

Perfectly normal.
