Hi Speedy,
If you need to take the spindle out, cut the pipe past the crimp line. Before you install the spindle back, make a light drilling on opposite side of the spindle and make a dent punch when installed plus your clamp. I'm not sure about your clamp because it's very hard to crimp or compress the pipe unless with very strong crimp. Maybe clamp won't do anything. The spindle will force fit into the pipe and only needs to stop it from moving. A dent will do.
