Ski-doo blizzard track falling off left side?

Question

The track is falling off the left rear of the sled at the bogey wheels.What could cause this?

Answer 1

I had a 79 blizzard 5500 with the same issue. On mine the track clips were falling off one by one. Track clips basically hold the track in place, they are metal pieces mounted to the track on the outside of either suspension rail/ or slide.
