I think that Karl is right on the money on this one. You can replace
the clutch and pilot bearing and resurface the flywheel, but if the
clutch actuator cross-shaft is worn unevenly from side to side, clutch
performance will suffer. After having seen a couple of the aftermarket
(probably Mexican) cross-shafts fail, I only buy the German ones with
the induction-hardened fingers. The rubber mounts are certainly a
potential issue, but the labor required to replace the clutch is
significant enough to justify the cost of a new cross-shaft if it is
worn unevenly.
