Default Clunking from back

Replaced shocks all around including donuts on back. When purchased, going over a pavement seam on the freeway would cause a loud clunk. I actually pulled over to check because I though a coil spring must have broke. Now 95% better. Still some clunking when going down a rough gravel/dirt road at 10 mph. Can't recreate clunk when parked by pushing down on each rear corner. A worn suspension bushing? Car has 111k miles. Ideas where to look?

grease the zerk fittings on both sides of the differential. Did you replace the front shock mounts? Always a clunker!

Yes. My test for wheel bearings has always been with wheel off ground push and pull wheel for play. No play.
