warped flywheel

I'm almost positive that my flywheel has been warped real bad. On a hot day I really have to baby the clutch and even then the whole car will just shudder real bad. The shuddering has been son bad that the cat converter has been loosened up a bit from all the shaking/vibration.

About how much would a replacement cost?- 97 sport, 4.0, AX15.

The only way to tell is after you've dropped the transmission to examine it and the clutch mechanism. A warped flywheel is rare enough that I sure haven't heard of one on a TJ. If you end up needing one and are in SOCAL, I have one I removed from my '97 TJ when I converted it to an automatic.

I'm changing the oil and looking over everything tomorrow since I'm heading back up to school at the end of the week, so I'l have some time to look around underneath. Do you have any ideas on what else could be causing this? I know that the flywheel was resurfaced a year or so back and I've heard that that can be a big no no for certain models.

Yep machining the flywheel is not recommended by the factory. Oil on the clutch disk can cause it to chatter and conceivably that the flywheel was machined might have something to do with it as well.

hmmm
I probably wont have the time/$$ to have it really looked at or taken care of in the near future. Is there any real long term damage that all this shuddering etc can cause, at least until I can have it fixed?
Also would you know how I could tighten up the converter, its driving me absolutely nuts every time I hit a bump

Converter? The only converter I'm aware of on a Jeep is the torque converter but that is only used with an automatic transmission.

That's a very good suggestion to investigate.
