Front right wheel rotor unstable

[divelab]

I recently changed my summer tires to snow tires and noticed after tightening the front right wheel to the rotor... there was a slight 'shakiness' to it.
Meaning the wheel was solidly fixed/screwed to the rotor, but it felt like the rotor itself was the piece that was unstable. I checked on all the other wheels and they were all soundly fixed onto their rotors and no shaking was experienced.

Together with a slight scratching noise I have been hearing for the last 4 months... am hoping someone out there can quickly identify the fault. Is this something that usually happens after 130,000 Kilometers?

I thought it could be a ball bearing issue... but not sure. Planning on visiting the garage before xmas in anycase.
Thanks in advance for any feedback.

That serious? Will defintely investigate it further and asap.

Is it typical for wheel bearing problems to impact the shakiness of a rotor -when the car is jacked up and you feel a slight looseness/wobbling of the wheel after it is tightened onto the rotor? I thought the noise I was hearing was down to the bearing issue, but didn't realise it was also now linked to this wheel problem.

Very definitely as the wheel hub is connecting to the outer part of the wheel bearing and the car to the inner part. In the good old days you used to set the wheel bearing adjustments by tightening the hub nut all the way up whilst rotating the wheel and then back it off one flat and put a split pin in. That gave just a tiny bit of movement if you held the wheel top and bottom and 'rocked' it. At least that's the way the old Police mechanics I used to work with taught me in the 1980's. No idea if that's how it's still done, but it may be. Any excess movement and/or noise was immediately investigated to see if the bearing had gone dry and was failing. Definitely something to be looked sooner rather than later. Any marks/pitting/blueing on either the bearing track or rollers was cause to change the bearing.
