Dang U-bolts!

Be sure you get the type with the knurled flattened portion in the middle of the U

Without that you will crush the housing tube. Also the torque is 45 lbs not 100, not that feels about right.

Look in the FSM to verify the number but I'm 98% sure.

That's just not true. All I've ever used are round u-bolts and I've never crushed anything. Crushing the axle tubes comes from over torquing the nuts and nothing more. You're correct on the torque spec. It's only 45LBFT.
