After several attempts at the various auto part stores, I discovered the size and thread of a bolt you can use as a puller.
16mm fine thread. The rear wheel axle does not fit on a 550.
A couple of bursts with the impact and off it came, easy as pie.
Knowone had a fine thread bolt of that size, so I hit an import car repair place and he dug around and came up with one.
It took a 27mm socket to fit it.
