Bell Crank Screech

[swift1b]

I think I found the cause of the bell crank screech in the left aileron. I inserted a mirror in the inspection opening for the bell crank and found the cable near the trailing edge rubbing the phenolite plate where the cable passes through the rib. I held the cable away from the block and moved the aileron and the screech was gone! I check the cable at the right aileron and found the same thing but it does not screech. There was no damage to the cable where it was rubbing against the phenolite plates at the bell cranks.Is this situation normal for the rearward cables? I inspected the entire run of the cables from the fuselage and found it centered in the rib openings. Will appreciate any comments...
