Front spindle unit bearing question

I came across this series of pictures of how the unit-bearing spindles are constructed on our trucks. I take it that the "inner race body" and "outer race body" have the actual bearing surfaces integral in the forged piece, and that's the reason why they can't be rebuilt.

Is that correct? I'm assuming there's no bearing race that can be knocked out and replaced.

The actual wheel bearing is a closed unit and can't be taken apart and put back together without damaging it. The spindle bearing that supports the stub shaft is just a small needle style bearing that can be greased, but I replace them if they're dry at all. They're only about $11 a piece i think. And yes, that is how they're built.

Reason I was asking is I bet a good carbide or ceramic insert in a stout metal lathe could cut out the bearing seat and make it possible to put in a new one. Just thinking out loud.

For the $100 they cost, I can't imagine it'd be worth the effort though...

Well they sure are a piece of crap! I can't seem to keep a set on my truck. Took it today to get new tires and alignment, sure enough one of the dang things was bad. Thats 3 in the last 3 years. The one that is bad now is the last one I replaced. I can change one out in 30-45 min, but they cost so dang much!!!!!!

Sorry to say No Num 2 & 3 wew after market, just don't remember the brand. Num 1 was oem, Money got tight so I has to go cheaper and here I am. Num 4 will be oem, money is better now. Still the after market should last longer than 1 year....
