Front Suspension 'Rough'

Since buying my W124 I've had issues akin to worn shocks and/or worn upper mountings. It felt like the wheel was hopping. Since one of the shocks was bouncing excessively I opted to change both shocks, upper mountings and rebound rubbers. I still have exactly the same issue when driving over road undulations.

I've checked the lower ball joints (taking up the spring pressure under the wishbone and then checking for freeplay) - nothing found, also found no play in the tie-rod ends or steering bushes. However, I did find that the steering damper was worn, collapsing and expanding with relatively no resistance. Could this cause the symptoms I'm feeling?

You bet. A worn steering dampner will cause excessive play in the steering when encountering road imperfections.

Great, then it's a relatively cheap fix.

Also check the sway bar bushings. They are cheap and easy to replace DIY. My car was having weird noises and clunks and it fixed it.

Interesting point! I previously had a groaning noise on one side when going over speed bumps and when bouncing the car. I checked the sway bar bushes and eventually traced the noise to the outer mounting point there the bracket that secures the sway bar mounts to the chassis by having someone bounce the car while I checked. Loosening this bracket revealed a dry, somewhat corroded surface with some evidence of rubbing. Some grease on this surface before re-tightening silenced the front suspension.
