Just to amplify a bit, the biggest problem with front wheel bearing preload
is that the hubs are a different material than the spindle, and the relative
temperatures change, thus differential expansion changes the bearing
clearance/preload. That's why you *don't* preload them on installation and
they're a little bit loose cold, they get tighter as they warm up. Using
the brakes makes them tighter yet.
BTW most solid-axle TRs also have tapered roller rear wheel bearings. Only
drum-braked TR2-3 had ball bearings.
