I've rotors (aka disk) machined (aka turned) or installing new rotors when replacing pads. Machining can be done on the vehicle with specialized lathe, that most Dealership have. For DIY when replacing rotor because out of limit or just upgrading, say too slotted and drilled rotors. Or turning rotors off the vehicle to prep for new pad. It is indeed best to do a front wheel bearing service at same time.
The Slee spindle tool, is a nice method to pump grease through spindle around axle getting grease into back of steering knuckle to axle brass bushing and needle bearing.
Some just press new grease in from back of knuckle while steering knuckle in place. Very difficult to actually get grease into the needle bearings this way. But does fine job of greasing brass bushing, provided no dirty gets in area.
Many on mud have made their own spindle tool for greasing, with plumbing supplies.
Slee tool on and ready to pump grease to axle needle bearing and brass bushing.

Personally I like pulling the steering knuckle the first time in on any 100 series wheel bearing service. It's and extra that does really add to time to a wheel bearing service. But this allows me too properly inspect all ball joints. Additionally I recondition and inspect steering knuckle, brass bushing, needle bearings, de-rust, rust prevent, recondition, seal and pack in grease by hand. It does requires a new seal be installed in back of knuckle. This is a one time service I do. After which I use the Slee tool each 30K miles when doing PM wheel bearing service.
Here is a rather nasty looking view of back side of steering knuckle (seal, brass bushing and needle bearing).

You have near every useful & cool tool there is. When you going to become my neighbor...

Once I had a grease press at a shop I worked in as a teenage. It was free standing with a 12" handle. Made the job fast and easy.
Anymore I just pack bearings old school, by hand. It doesn't take long, but cleaning & inspecting does.
Properly packing wheel hub cavity with grease during assembly, is very important. Failure to do so will result in bearing burning up.
Side Note: Loose wheel bearing can result in chatter (vibration) creating damaging heat. If so loose wheel hub wobbles, the wheel speed sensor may get bad reading. Wheel speed sensors reads the area circled.

Typically a shop, INDY or Dealership does not do a proper wheel bearing service. Reason; it's a ~3 hour book rate job (~$350). To get the job done and make within book time or sooner; they don't clean, (which means they can't inspect properly among other things), don't replace grease in hub, just press old grease out of wheel bearings with new grease (mixing greases), don't set BP preload, don't replace or check snap ring gap, don't grease axle bearing & bushing.
Not very good video angles of wheel hub. I was just really after showing how it pack bearings by hand. You'll get it when doing the job.

After packing axle bearing and bushing with grease. Pull axle out by hand will not settle the grease. So the snap ring gap will be larger than first reading indicates. One can assembly drive to settle and come back and replace snap ring and set gap. I just grabbed up some tools and made a puller. Some in mud have fashion a real simple tool for this.

I must apology for my videos. My camera shuts off after 7 minutes. So one must watch many, to see how to assemble steering knuckle and wheel hub. I just started doing some videos and posting upon a request. They just helpful, but not a step by step how to. Taking pictures adds a lot of time to my jobs, videos adds even more time. So it is limited as to what I show. They only video of dis-assembly is remove cone washers. This was the very toughest hub flange removal I'd every done. Someone used FIPG and glued it and cone washer in. Other than cone washers it just take it apart, nothing special. Just don't pound on parts with steel. Don't pound I hub flange itself either, unless replacing it!
These cone washers were glued in. What a PITA, but finally they popped out. This is a 2007 Series 100 Land Cruiser.
