The MoT should in any case be due as the three years comes up. Good point - I was conscious of that this time last year, and keen to make sure there was no warranty work outstanding before the deadline, hence getting an MoT after my service/MoT was cancelled even though we were in lockdown. I’d just seen the first reports of rear hub carrier issues (worn/collapsed bushes) and asked the tester to look out for it specifically. It was fine, as I expect it will be this year after <1000 additional miles.
