Is my SDM about to go out?

I have just got a used 50-135mm yesterday and everything was perfect. just an hour ago though i notice that there's a sorta rough bumpy sound/feel when moving the focus ring from minimum to inifinity. you can also hear it when the autofocus is doing it. strangely enough when the lens isn't attached to the camera it doesn't make the noise nor do i feel the bumps. any ideas? is this my SDM dying?

Ok so just last night I was using the lens and the focus went to minimum focus distance and then stayed there. I took it out of AF and tried it manually but the focus ring turns but doesn't change the distance scale and therefore is now stuck in minimum focus distance. is this SDM failure or is this like the whole focus thing has failed? this lens is a newer Nov 2012 bought lens which should've been fixed of the main issue of this lens in the past.

Try to rotate the screw drive focus with a small screw driver, hopefully it will free up the sticking gear or motor.
