Cheers guys.
Had suspension bushings replaced less than a year ago on the front. Also had new front tyres and tracking sorted about a month ago.
It’s really hard to tell but I think it might be one of the back wheels rather than the front. Kind of feels as if somebody was standing behind you, moving your shoulders back and forth!
Think I’m going to have to bite the bullet and take it to a garage, but I always feel like they’re taking the widdle.
I will jack it up and try the things you’ve all suggested first though.
PS, it’s done about 46,000m is that a reasonable age for a wheel bearing? Can’t find anything in the service history about them being replaced before.
