[DeTomaso] Axles and halfshafts

[Will Demelo]

I'm putting a winter parts list together and am concerned about the axles and halfshafts. I've read about these breaking and making a ness of the inner body panels.
I have 450hp to the wheels. I will definately replace the bearings and u-joints, but do I need to replace the axles and halfshafts ($$$$)? Can the original halfshafts actually break in half or is it the ujoints that fail?
