It's purely on play at the wheels as I understand it. My Focus has a
noisy bearing. I thought it was going to fail last weekend. I even asked
the tester about it when he passed, it - no, if there's no play, it'll
pass. Any play, it will fail.

not quite true it can have a degree of play, but will fail on excessive play
or roughness in the bearing.

front suspension & wheel bearings.

It depends. Some older cars had adjustable front wheel bearings and these
are designed to have some play. But most are none adjustable and have no
play.

Nostalgia! I remember taking out the split pin, turning the nut to
the next castellation, and replacing the pin.

Thanks Reg. I'm still miffed it passed, as it's clearly noisy. I thought
that would show up some roughness.. apparently not.

if it is a driven wheel then it is much harder to feel/hear the roughness by
spinning the wheel, it just can't be spun by hand fast enough. Which was
one of the good features of the old test, when cars were actually driven to
assess their quality as part of the MoT test.

Other thing is failure of these types is rare. Or is on mine. They seems
to be a service item on many other cars, not cheap, and often a bugger to
replace.
