Remove brake disc (caliper etc).
Clamp a magnetic base to the side of the trailing arm (I assume you don't have aluminium ones fitted!). If this doesn't work then get something big and heavy that won't move {tool kit?} and position it at a suitable distance from the hub so that you can...
...Position your clock gauge / DTI so that the probe will run on the surface of the hub. Turn hub by hand and watch how far that little needle spins. As it isn't a really smooth machined surface you will get some variation in needle output (?!).
If the hub is OK then check to make sure that the bearing clearance is still good => pull hub towards you and away from you - in and out towards and away from the differential.
If that is OK put the disk brake back on and repeat the test above.
Alternatively you might find it easier to check run out on the end of the hub - that would be checking for out of roundness in a vertical direction instead of lateral direction.
