I would have thought most people here are doing much more complicated work all day.

All four bearings are part of an assembly that bolts in. 8 or 12 bolts depending on position. I'm lucky that I don't even need a press.

The wheel comes off (5 bolts), the brakes come off (2 bolts), the axle/hub bolt comes out (1 bolt), and then on the front there are four bolts holding the assembly to the car. On the rear, nothing holds it on except that hub bolt.

Use a torque wrench to get them to spec. The kits came with new bolts. The axle bolts go on tight tight.
