Mike,
The carli set (top & bottom, left & right) ranges around 900.00 to 1100.00.
The spyntec kit uses Dana 60 parts, they are available at your local parts store also, costs break down as follows (rough prices):
spindle bearing kit w/seal = $12.00
inner bearing = ~$40.00
outer bearing = ~$40.00
replacement dually hub w/abs = ~$550.00
35 spline stub shaft = ~$110.00
MM locker = ~$180.00
You see the prices for yourself here:

Hope that helps.
