PER CREW WHEN ONLY ELEVATOR MOVEMENT, HAD TOO MUCH RESISTANCE.  WHEN ONLY AILERON MOVEMENT, RIGHT SIDE TOO MUCH RESISTANCE.  WITH SPOILERS DEPLOYED AILERONS OK.

QTY ON RTBL .94, QTY AFTER OPS CHECKS - .66.  NO STATUS MSGS OR OTHER DEFECTS NOTED.  ACCMP'D ELEV AND FORCE CHKS.  SVC'D R HYDS.  ALL CHECKS GOOD.  NO HYD LOSS.  EDP GOOD.
