Default Servo on the way out?

My 50cc SBach has one aileron servo in each wing - Hitec HS-5625s. The one in the port wing sings at while idling at center; I suspected the linkage at first but I've had it off and apart and it appears to move smoothly. In addition, the port wing servo will not hold the aileron up when the Rx is off. That is, if I deflect the starboard aileron up (as in, towards the sky) with the rx off, the servo holds it there. On the port side the aileron sags to just below neutral.

Is this servo on the verge of failure?
