Don't be too sure.  I have the same thing in my '79 Malibu.  The first
thing done was to remove a clip that holds the cable to the frame.  This
was done by the factory and allows the cable to flop to a "happy"
position.  Apparently the clip caused it to take too tight a bend.

But that didn't eliminate the problem although it made it better.  I
pulled the dash apart and yanked the speedo.  Looks like the cable
housing has a steel cup at the speedo end, and the cable itself has a
piece of nylon moulded on to keep it from going in too far (so you can't
replace the cable from the tranny end).  Anyway - after lubing the whole
cable several times to no avail (couldn't see any shiny spots on the
cable either), I finally took to lubing the nylon and steel cup.  That
usually stops the squeek for a year or more.  Next time, I am going to
try lubriplate in the cup, it should last better than speedo lube.
NOTE, don't put it on the whole cable - it's too thick in the winter.

If you want to lube the cable too, while you have it apart, get a proper
speedo cable lube.

Hope this helps...
