88? my 89 is starting to do that too. My older one started and I didn't lube it and it broke. Anyway, I believe I saw some 'special' speedocable lube that was really , well disgusting and didnt wash off my hands very easily, like it was some sort of graphite special stuff. Cable comes out, from the speedo end of the sheath because that's where the crimped on square drive end is , wiped with lube from a to z and then back in. The trans end on mine was actually a squared cable at the last inch or so on that end. Sure would be easier to just drool some oil down the cable. If it does or did break, there are 'universal' replacement cables that you cut to size, if you are lucky enough to get the exact length right.
