The manual says to install a new new flange nut. Did you, and if so where did you get it? Did you just use a chisel to crimp the nut once torqued?

Also, did you have to remove the hub completely or partially to get the axle out?

There doesn't seem to be a lot of info available on this. I'm wondering if I should take a bunch of pictures and do a write afterwards.

I plan on buying the Timken 513130 bearings from Amazon tonight, but figure I should replace the nuts as well.
