Default Restrictive movement of two identical Hitec servos

I have two HS 322HB Hitec servos that have developed a common trait. When both are tested on an activated RX, also Hitec, the arm movement is slow on both and approximately 20 degress arm rotation in both directions instead of the usual 60 degrees. The older servos, you could make some adjustments by turning the wiper pots by going through the output shaft. I'm reluctant to do this with the newer servos of today. I'm aware that these units are not digital, but this activity at first to me appears as though these servos were programed this way. Any ideas would be greatly appreciated.

You did not mention brand &model type of TX.
HS-322HD are standard non programmable servo, 60 gegree plus 15 degrees each way for trim = 90 degrees total.
(. Speed (4.8V/6.0V): 0.19 / 0.15 sec @ 60 deg. )
If not turning correctly as above, check the EPAand Dual Rate switches/settings on your TX.
