I only chime in because I 'JUST' did both lower control arms on the allroad, and my mounts were spotted leaking last month and the subsequent driving brings me to today with the vibration under load.
I have a slight wobble too due to the HP2 calipers that tend to leave pad material on the rotors causing the shudders...but that is only on braking from highway speeds.
Its something you might want to have looked at, or look at yourself if you can get under there to see the mounts.
