One of the axles I rebooted was my torn-boot OEM axle. Upon disassembly, it was totally fine (no grit in the bearings etc), so it has worked out well with a simple reboot despite having near 200K on it. I think the Toyota CVs are pretty robust and tolerate being driven with a torn boot better than any other vehicle I've ever driven.
Another option would be to get a set of NAPA/Cardone reman OEM CVs - for a 460/5th gen 4Runner - and send your 470 axles back as the core return.
They are all of $86 on Rock Auto right now. They'll be a bit more at NAPA but they'll have better warranty support, and you can open the box to verify it's a true OEM axle before actually buying it. Since you are not lifted, the aftermarket neoprene boot should last at least a couple years. When they rip - or when you lift - you can re-boot them with aftermarket high-angle boots. Rebooting is easy enough that I'll never go back to complete axles.
All the "reman" axles are anyway is a disassembly, clean, and re-boot with new grease and a new axle nut. Considering they do them in Mexico with low-cost labor, it's pretty easy to see how they are done so cheaply.
