My best guess is that there is something wrong with your speedo gear or sensor. Easy to check...on your tail shaft housing just above the drive shaft there is a sensor. It is held in by 2 bolts. Un bolt...ccheck to make sure all of the teeth on the attached gear are intact...then reverse the process. Only thing i can think of...good luck.

Rubicons don't have speedo gears they are electronic. They use a tone ring and magnetic sensor so checking it's condition is useless but you can look anyway. Is it only the speedo gauge that is bouncing all over the place?

Check the wire for that ring/sensor. It may have worn through and is making contact on the frame/suspension. Many vehicles use a similar set up. I have seen many get pinched, either between suspension joints or between the frame and a road object. Some wear through over time.

aight this is what i got.
forgive me for spelling it out but my knolwedge is limited.
unpluged the wire harness and the speedo quit alltogether and resumed when i pluged it back in (of course).
pulled the magnetic sensor out of TC and wiped it of and reinstalled, still not fixed.
and the third pic is a panel mounted to the underbody the thiese wire harness run to.
any thoughts if the panel and attatched wires are the prob or should i replace the mag part in the TC?

Do a gauge test. Hold the odometer reset button in and turn key to "on" gauges will go through a test, see if speedo goes from 0 to about halfway and pauses, and goes to all the way pegged

So it never went to just a little past 100mph? Mine does, so now I'm thinking it might be the gauge.

One thing you don't want to do is replace a bunch of parts that don't need to be replaced if they don't need to be. A gauge cluster is expensive. One thing you might try is cleaning the contacts for the gauge cluster where it plugs into the dash. I know that might be a long shot but it's free.

Look at the price of the sensor that goes in the transfer case. If it's fairly cheap I would try one.
