Front rotors are not at all difficult.

They are conventional in that the rotor is held to the spindle via a retaining nut and two tapered roller bearings allow rotation.

When you remove the rotor, the only difference is that you replace only the rotor and not the rotor/hub combination. Accordingly, you need to separate the rotor from the hub, which takes some muscle to break the socket head cap screws.

The inboard bearing is retained by a grease seal which needs to be replaced during this process.

The bearings should be thoroughly cleaned and repacked when the rotors are changed.

Setting the clearance in the bearings is a bit challenging. The spec is .0005", which is basically impossible to feel. You want the very slightest bit of clearance.
