Axle shaft diameter

[CalsXS2]

I'm getting ready to pull my wheel bearings. I want to try the concrete anchor method where you expand it then drive it out from the backside.

So I'm at work where we sell the anchors. But I forgot to bring my hub. Can someone give me the diameter. Preferably in inch's. I have a 1/2'', and a 3/4'' anchor on hand.

front axle is 17mm between 11/16 and 3/4
rear is 20mm a little bigger than 3/4 hope this helps

For the rear wheel, you don't need any sort of puller or removal aid. There's sort of a built-in bearing remover in the form of that tophat shaped spacer fitted into the left bearing. Find a socket that just fits on that spacer and drive it down into the hub. It will push the center tube spacer, right wheel bearing, and grease seal out the other side. Then it's a simple matter to drift the left bearing out with a long punch through the hub.
