jerking at 50

Well if I go over 50 and rev it like I said it it will still jump at me. I just have to ease into all speeds

steadily power through the jerking.

Not the CPS then. If you have steady power, with no loss, then your problem is most likely in the drive train or suspension. I would check the ujoints first. Also; have some one follow next to you on both sides while you drive into the problem. Have the observer look at the wheels for hop or shake.

Thanks I'll check that first but if that's would it make the check engine light come on?

I'll check that first but if that's the problem would that make the check engine light turn on

No. If your check engine light is on you should have it scanned with an OBD II reader. Jeeps also have sub codes for their transmissions, so whether the code is in the engine or trans you should find the culprit.
