Go to a wrecking yard and grab a rear spindle/hub assy off some front wheel
drive car. If you look, you'll probably be able to find one that simply
unbolts from the axle (check out the VWs; I think Jettas are like this).
It'll probably be cheaper than some new gizmo, naturally and well sealed
against the elements, and way-overkill structurally, so you'll never have to
worry about wearing it out.

Cheers,
