Sounds like fun. So, only one maybe constructive comment. Wheel bearings.
Apparently for a while one of the big three had a lot of trouble shipping cars across country. The wheel bearings would fail prematurely. It was traced back to shipping them via rail. The clack-clack-clack of cars rolling over gaps in the rails is actually quite violent. Especially since the wheels aren't rolling, so the grease oozes out from between the rollers and the races. Basically you have metal to metal contact, with the train clack-clack clacking in them like a hammer. This damages the bearing surfaces leading to very early failure.
It's the same reason you don't want to beat a rusty brake rotor or drum off a wheel hub on a car. Yse heat or a puller, or you'll be replacing bearings real quick.
If bearings are rolling, there is a film of grease, so there actually isn't contact.
We really need a tribologist in the house. What's that, like the second time in a week???
That's like towing old stickshift cars on their rear wheels for more than a few miles. If you do this, remove the driveshaft so the back bearing in the transmission doesn't burn out, because it's the drive gears that toss the oil about and keep things lubed.
If the lube is right, steel-on-steel bits shoon't really ever come into contact.
