I have a 95 ZJ with the 5.2 V8 full time 4wheel...

Over the past few days the speedo has been acting up. I can be going down the road at approx 45 mph and it will "flutter" between 55 and 80 mph quickly. Last night it sat on 0 when I was going down the road and when I punched the gas a little it jumped to 100 and bounced around....this morning it almost made a full loop. It will return to 0 most times but will get stuck others.

Before I start tearing things apart, is there something that I should look at first? Anybody had this problem before?

Please help!!!
 
I'd start by checking to see that the Speedo gear is secure in the T-case and then I'd pull the gear to check the condition of the teeth. Also check the wiring harness for any abrasions and shorts.
