After playing with it for some time, I figured out how to assemble it. The trick was to pull the circlip and remove the shaft from the housing (you can see the clip at the top). I had the u-shaped springs somewhat in place, but instead of the ends touching together as pictured, the shaft end sandwiches between the two spring ends. This required two sets of hands due to the tension. I would have take a picture, but I wanted to slide it into the housing before it sprung apart again. lol. Verified with the multimeter and it works.
It failed because the die cast housing flanged opened up enough to allow the internals to pop out. It's bound to fail again in the future from bumps/vibration while towing.
