Well you had me curious, so I had to remote home, put that VIN in (ever try to read a VIN from a picture on a window sticker online, remember the digits, then launch the EPC from a VPN on mobile? it's not fun!)
The major assy's are not listed in the same way the EURO one's are, but if you dig into the notes you can find reference to them having ZQ0 option order code. From there you can pop up the service info and it definitely lists the axles as having ZQ0 and the service info for them (but it doesn't list the axle number specifically, which is weird), pretty cool info actually It directs you to the 463.234 sheets even though the VIN is 463.255. It does the same for the EURO VIN's I have (which are 463.234, 463.272, etc):


They must use earlier pictures for the repair data (why take new pictures when it's kinda sorta the same, EPC is the same way with diagrams) as you can see, the bracing structure on the front axles is changed a bit from the pictures I see. Or it's just the angle, not sure.
Maybe since they are new the full axle info will populate in the EPC in the future?
You know, just in case anyone here buys a G500 (G550?) squared and decides they want to service the portals on the driveway? (yeah right

)
