Wheel Bearing Location?

The instructions for my P2K E6 says to lubricate the wheel bearings and since I’m new at this, I’d like to know where the heck they are so I don’t oil the wrong places
In the photo below (click on it to enlarge it) are they at A or B? My guess is B

B is probably the best place to add some oil. Truck sideframes no longer have bearings.

B are the bearings – the axle ends don’t even touch the sideframes of the trucks. You can even remove the sideframes and the engine will still run just fine.

I appreciate it, B it is then.
