Looking under my new 99 hi-lo and noticed that at the left hand side double pulley one of the cables appears to have slipped over to the other side. Cable is in really good shape, everything is working fine, but I am worried about it. No way to nudge it over now due to the tension. Wondering if there is a way to loosen the tension and safely move this cable back over - without messing everything up. Looking for suggestions. See pic
