When I lube mine, I completely remove all linkage rods from their pivot points, cables I only disconnect. I clean each ball and thouroughly clean out all ball sockets. Then I lube the sockets and reassemble the linkage. Some of the ball sockets may be a little stiff and hard to pop off the balls. A small screw driver placed between the socket edge and whichever lever it is attched to will allow for a slight twisting motion which will pop the socket.
I prefer to use a light grease as it stays on longer, but it also has a greater chance of collecting dirt and debris. Remedy- clean and lube more often.
