A further update - ours got waggly as I noted previously. Now re-greased and it's smooth again.
I'm wondering now whether ours ever actually needed replacing. Perhaps the original waggle was just a lack of grease. Worth a try for anyone else with the same issue.
Unfortunately the garage didn't renew the boot - it did get a new one when originally replaced though. I'm thinking that either the new one is split or it's not being sealed on properly. We'll see...
