Had a massive front end shimmy that was getting worse through last week and the weekend.
Finally crawled underneath after work on Monday night and found the steering damper bushes loose.
Tightened the nut on the pin end at least 1.5 threads, and gave the Panhard rod clevis bolt and nut a 1/4 turn for good measure.
Problem mostly solved (now for another ounce or so of counteract balance beads in each tyre)
