I had never
taken one apart either until the cable broke at the upper swage fitting. It is very simple when you get into it. I did as Dave said, then removed the keeper pins in the turnbuckle so I could take it all apart, after that I took the anti-spin fitting off the bottom and the whole thing came apart. Watch where the metal, and nylon washers go, and in what order then you can clean lube as you see fit. I replaced the cable and put it all back together in less than an hour.
