That certainly should be looked into and corrected as necessary.
To inspect the front differential mounts, you'll need to get all 4 wheels off the ground and with the motor running, put the transmission in drive and then reverse, with an observer watchin the front differential from underneath. If the mounts are bad, the observer will see the front differential move, as well as hear the clunk.
I’ll have to check those mounts. Rock auto sells a front end rebuilt kit that comes with inner and outer tie rods, pitman arm, idler arm, idler arm mount and some bushings so I have that on that way. That should take care of all the play
