Wheel bearing gone after my MOT

I would say they've tightened up the wheel bearing to remove excessive play and thats causing it to hum now.

Not an unusual thing to do.

If they've had to tighten it too much, it hums. Sometimes it works out, sometimes it doesnt.

Adjustable taper-roller bearing? On something as modern as a Note? Really...?

Is that not a thing now?

Sorry.

The 1950s called - they want their running gear back.

They do just go noisy. The MOT looks for excessive play in the bearings, if that had been present at the time of the MOT, it would have failed, so you are lucky there.

I had one fail with little warning.

Driving down a dual carriageway 40mph, pulled up at the shops all fine. As i pulled away there was a grinding noise, the bearing had collapsed.

The only sign of an issue if you were quick, was a single flash of the ABS light about 3 weeks prior. It was one of those did it flash or was it a reflection?

Get over yourself.

I've definitely seen it done as a short term solution to not have to replace a wheel bearing for MOT

Last car I had with taper roller bearings was in the 80s.

A normal parallel bearing simply won't, can't "adjust". The forces of the fastener are taken entirely through the race walls, and an increase in torque simply is not passed on to the bearing itself.

I've had a car pass its MOT with a noisy wheel bearing (which I subsequently had replaced).

Yes, the test won't pick up a bearing that's loud at road speeds, unless it's also rough or audible when the tester just spins it slowly, or unless there's actual play in it.


I just had a front replaced a week or two back - it was very, very loud at motorway speed, started to be audible at 15-20mph, but was quiet when spun by hand - and had zero play. When it finally got winkled out (it put up a hell of a fight), it basically disintegrated.
