I think this is because the tracking

I've not seen a mechanism where "the tracking adjustment screw locks
down". They're usually a rather cheesy piece of garbage where the
tracking adjustment acts as an end stop, and the force of the tension
spring is used to hold the wheel axle against it. This works, but it
will "give" in one direction if you pull (or maybe push) on it in one
direction.

To check the bearings, you're usually best to grab the unbladed wheel
at the _sides_ and wobble it, not the top and bottom. This may also
show up sloppiness in the tracking adjustment trunnion, but that's a
design problem, not wear.
