Lately my 76 Rabbit has been having a strange clutch problem. When I push
the pedal down and start to release it, it feels like the clutch is
engaging immediately (the car kind of jerks forward like I released the
clutch). But if I continue to let the pedal up it disengages again and then
feels normal the rest of the way as the pedal is released.

The clutch doesn't slip at all, there's no "grabbing" or "jerking" as
normally happens with a broken spring/warped disk/oiled disk. When it
works, it works nice and smooth.

To complicate diagnosis, it doesn't always act this way. I may drive it a
few days without any issues, then other days it may act up all day long.

I have about 70K miles on the clutch, and about 15K on the new clutch
cable. The clutch cable is properly adjusted, and I have no other clutch
problems or symptoms.

I'm not eager to replace the clutch again. Would a throwout bearing cause
this?

Thanks,

Anthony
