Dogbones only last a few years for me Shock mounts last a fair bit longer. The new Meyle HD ones are reinforced and claim better longevity. Dogbones/Pitman arms don't usually clunk like shock mounts can. Have you actually inspected the shock mounts?

You can remove a wheel and see if you can shake the shock piston near the top to see. Shine a light up won't really help you see them, to do that you need clean hands. Remove the rear seat top cushion, C pillar lights, covers and finally the parcel shelf and rubber shock mount seals/covers to really see them up close. For me, going to all that trouble necessitates having a spare set of new mounts in case they are toast- with all the interior items out of the car, it's a 10min job.
