There are some very beefy parts. The hub itself, and the a separate 1/2 prop on each end. Inside the hub is a set of gears and likely ball bearings and lots of other parts to make it all work and not come apart. There are shops that do nothing but repair the props. Few if any mechanic has the proper tools to take it all apart, get it perfectly balanced and tested to meet FAA rules. Of course a certified mechanic has to take it off and put it on and everything gets entered into the log books.
They also take everything completely apart, magnaflux or some other sort of non destructive dye infusion inspection of the hub and measure the gears and bearings. It is not a simple seal replacement.
I envisioned a book the size of a regular dictionary or a long novel for the log book for our 182T log books. It is a small suitcase and is heavy. There is an entire dictionary size book for just the prop. Everything ever done to the airplane except adding oil and gas, and cleaning the windshield is logged, signed and documented. That set of log books can be 1/2 the value of an airplane if it is lost.
