Context for the inexperienced: these are cone seat GM lugnuts, the cone portion is supposed to face IN towards the wheel as they are self centering, not OUT… guy didn’t know wtf he was doin

How the fuck do you adjust a bearing?
There’s a nut that you tighten that changes how tight the bearing is being squeezed. You adjust it so that the bearing turns but doesn’t have any play
More specifically, on modern cars, you’ll normally have a sealed bearing/hub assembly, which does not need adjusting.
The ones that need adjusting are where you have an open spindle, the hub and [rotor|drum] are one piece, and the bearings are open and need to be greased. You’ll have an inner bearing, then the hub/brake, then an outer bearing, topped off with a big nut. You snug that nut down until the spinning hub just starts to get tight, then back it off a 1/4 turn and fix it in place with a cotter pin.
More specifically modern tapered bearings are designed to run under continuous preload (the shaft inside with a nut provides constant clamping force so that the bearing is constantly in contact with its entire bearing race). These older bearings run with no preload, I think largely because machining tolerances were poorer and the races were not always perfect, so the weight of the car applies load to force bearing contact only where needed. The downside is that these bearings need repacking with grease and adjusting very frequently.
I guess I’ve only ever worked on pressed bearings, because I’ve never heard of that.
Yeah, your average passenger vehicle won’t have them. Trailers and heavy duty trucks use them though. I only know about it through YouTube
