Cool actuator weird behavior

My actuator is acting funny.
This is the situation.
Looking the antenna from the back it is mounted where fully retracted is at SATMEX5 and fully extended is past PAS3R. I never go beyond to avoid getting stuck so I stop at PAS3R to watch Teletica.
Sometimes anywhere I move the dish lands on the perfect spot as memorized, but sometimes it lands off by a little bit. It shows the memory allocation with the name given but it is off.
If I do the run again it stops at the right place or sometimes worse.
One example if I'm watching PAS1R and I go to Intelsat805 it will not land correctly but if I go from PAS1R to PAS9 and then back to Intelsat805, it lands on the correct place and there is no need to compensate manually.
Sometimes happens when I go from Intelsat 5 to AMC4 fails but if I go from SATMEX5 or SATMEX6 to AMC4 it lands in the correct place.
Everything appears to be tight with the exception of both screws # 7 on the polar mount, that with all the washers and nuts show too much play.
Have you seen this before?
