Well, to anyone that may be doing this in the future:
On the sprocket side of the assembly, there is a spacer that is held in with grease. It will release with a gentle pull.
The back (inside) part of the cush drive can be gently pried out with a small screwdriver.
This gives you access to the rubber bumpers and a bushing.
I cleaned up the area I thought was heat discolored and realized it was corrosion. It cleaned up well with fine grit sandpaper.
