Deezel,

I don't remember needing a special wrench for the axle unless the new axles are different than the older ones. I replaced at least 4 axles and didn't need any special tools. There is a bolt in the end of the axle that holds the axle in the spline inside the bearing carrier, but a regular socket was all that was needed to loosen or tighten it. If I remember correctly, the older 220s had a larger size bolt than the 240s.
