That's what's left of an upper thrust bearing. I've NEVER seen one so worn 
out. You're supposed to have 2. The lowers don't need thrust bearings, as 
they are fixed by the far ends of the bars. They get a large O-ring instead.

It is VERY common for the upper torsion bar to get loose in the left upper 
trailing arm. If left unattended, this will rather quickly auger out the anchor 
hole in that arm. It can be fixed, but this can be difficult. Check the left end of 
that bar. If the dimple in it has worn to a slot you'll need to flip it over and drill 
another (deeper) dimple. Then you'll need to weld some fresh metal along 
the edges of the flat on the opposite side, to fill the now enlarged hole in the 
arm. Note that the "flat" in that hole is no longer flat, so a flat bar will always 
be free to rock in that hole, no matter how tight you make the set screw.

This is one of the weaknesses in the Type 3 design.
