Front wheel hub assembly replacement diy?

So my 2012 C63 AMG with just 30k miles has a bad wheel bearing. I'm pretty confident I can replace it myself except I don't know what special tools (if any) or procedures are necessary to do the job properly. I looked for info on this forum as well as Google and didn't come up with much. Has anyone done this job before or know where I can find info like torque specs and the such?

See that big nut at the end of the hub? Take it off with a big wrench. Good luck, it’s probably at 200ftlbs.

Heres a C-class video. Our cars are going to be sort of the same. No grease cap, and you have that big nut instead.

Thanks, I have seen that video and realized it's not quite the same as my car. Im sure I can just figure everything out as I go. I just want to make sure I have everything I need.

What have you noticed differs between the C-Class in the video and your car?

I've only taken the wheel off to inspect the bearing so far. Didn't have much time to get into detail but there is no dust cap and instead of that axle nut in the video it has what looks like a 12 point nut. I can take a pic later. I was under the impression that the actual bearing is not serviceble so I will need to replace the whole hub assembly.

C63 wheel bearing is nothing like the links and videos posted. 4 bolts hold the assembly to the vehicle...thats it. Far simpler than the typical Merc setup, most importantly do not remove the large nut on the from of the hub, just the 4 bolts holding the hub to the spindle.

Would you happen to know the torque spec for those four bolts?

Great job, Kyle. I wish we had more vendors who were this much help. I've moved you guys to the top of my "look here for parts" list.

Ha, had no time to snap a vid today but this is how the C63 hub is designed. Hub and bearing is an assembly and then a stub is shoved in the center so the abs can read wheel speed. Stub also structurally supports the bearing. We run studs on the racecar, disregard the studs.

Just finished up replacing my hub assembly. Was pretty easy! I just can't believe that 4 small bolts hold the hub, rotor and wheel on. Seems like it should be a little beefier
