I checked it out today. It's still a little noisier turning left than right, but it's nothing serious with the wheel bearing. On removing the wheel and checking for play, nothing was found to be loose or noisy. The CV boots are fine all around too.
It still feels very squirrelly on the highway though, especially going over bumps.
I didn't see anything amiss when I looked underneath, and the tires looked fine, so I bounced the 4 corners. The retral sinistral / left rear / driver's side rear bounces about 4 times before it stops. The other 3 corners go down, bounce up and then stop, as they should. It's clear it needs a rear McPherson strut. I'm sure it'll be much more pleasant when that's replaced (with its right-hand mate as they need to be replaced in pairs). That probably means an alignment too as the car has an IRS.
[edit:] tyop.
Cheers,
Scott.
