Jeep jumps!

When I let the clutch out in 1st gear, and easy on the gas, it jumps like Im giving it gas and letting off fast over and over. Any ideas on the cause???

So, the first step is to fill out your profile so we know what we are working on.......
That being said, assuming the RPM's are steady, it sounds like the clutch is juttering/grabbing. There are a couple of causes for this:
Worn clutch
Contaminated clutch
Hot spots on the flywheel
Broken motor/t case mounts
Worn clutch linkage

Paperwork will ruin any military force.

Is it sometimes, or every time?
What is the mileage?

Any way you look at it, unless it is the clutch slave/master cylinder, you will be pulling the tranny.
Not a hard project, doable in a garage or driveway.

My 2001 TJ, 4.0l, 5-spd did that when the throw out bearing was going bad. Not all the time, just some times. 135,000 miles, I think. Not sure if original or replaced before.
I ignored it until the throw out bearing fell apart on me in Brigham City, UT and I could no longer disengage the tranny while the engine was running.
Luckily for me, we tow it behind our rv. We were headed for home from a long trip, so just hooked it up and towed it the 1200 mile back home. Put in a new clutch and throw out bearing in it in the garage.

It has 79K original miles and only does it sometimes. Thats the only gear it does it in.
