I have a K-3 which I bought last year second hand. never had any problems with stabilization. I got the O-GPS1 module for Christmas, didn't have much time to test it properly.
I also have the faint clicking sound along with the faint "grinding" sound of the stabilization working. Actually it is more like a little gap in the sound of the stabilization "grinding".
So far my tests showed trailing but it was very close to the minimum operating temperature of -10°C, the trailing was mostly north-south direction. I also have 10°deviance for the south direction after doing careful normal and then precise calibration. I don't know if 10°is acceptable or not. I would be much happier with 2-3°deviance maximum.
I'm kind of worried if that clicking is showing something at fault but it is very orderly, precisely doing it at every second of the Astrotracer exposure. No such clicking when I wiggle the camera a bit in Live View with SR on, only the louder movement of the sensor position reset.
Maybe we could do a collective complaint to Pentax on this issue even if they tell us it is normal.

I forgot to mention the faint "clicking" is exactly one second no matter if I'm using 16-45mm lens, 35mm lens, 50-200mm lens or a 400mm lens. It is also present regardless where I point the camera (north, east, south, west, directly upwards etc...)
