I don't know about how yours is run, but I just recently replaced my whole cable and it took me all of about 15 minutes to do the whole job. I would say if you had help, you could just unhook both ends and hook up a drill at the speedometer side and turn it slowly, the person underneath could tell you if it was turning. If it is only you, I would just remove the cable completely then check it the same way. Someone else may chime in with a better or easier way to check it.

Not the whole dash, but enough to get the gauge cluster out far enough to disconnect the speedo cable. Once you dis-connect both ends, you should be able to fish it out.

Ok. So I spun the gear on the cable, and its not the speedo cable. I talked to the transmission warehouse here in town and they have the gear inside the transfercase but said that it takes advanced calculus to figure out which gear matches up with the it on the speedo cable. Anyone have any help for me please. I flunked calculus.

It's easier than you think. If you can find out how many teeth the drive gear has, what you're rear diff ratio is, and how tall your tires are there are calculators that will tell you how many teeth you need on the driven gear.
Here is a simple one:
Speedometer Gear Calculator
Usually you'll put in 1000 for revs/mile.
