REAR AXLE ON LEFT BECAME VERY NOISY AGAIN AROUND 57K MI, ESPECIALLY ON FREEWAY AND HIGH SPEED. TOOK IT TO DEALER AGAIN (06-22-04). THIS TIME, DEALER (SCHUMAN CARRIAGE MOTORS INC., DBA SUBARU OF HAWAII, ALSO DBA AS WAIALAE SUBARU) DISMISSED NOISE AS FROM TIRES, REFUSED TO HONOR WARRANTY, AND CHARGED US AN UNDISCLOSED $96 "DIAGNOSTIC FEE". UNPLEASANT EXPERIENCE AT DEALERSHIP CAUSED GREAT EMOTIONAL TRAUMA TO MY WIFE.
