+1The only good way to bleed a Jeep clutch is to remove the slave cylinder from the bellhousing and pump the slave cylinder piston several times (usually takes 20-30) while someone keeps an eye on the fluid level (should be about half way) and air bubbles in the master cylinder. Once there is no more air bubbles, but only fluid, you're done. Factory Jeep slave cylinders do not have a bleed valve.
Oh, and don't forget to take the inner liner out of the master cylinder
They are relatively easy to bleed...not sure where all the "impossible to bleed" comments come from.
Wear a leather glove and it's easier to push the rod in. Do it slowly though so you don't spit fluid up out of the master. Plus going slowly allows the helper to watch for the air bubbles. When you think you are done, push the rod another.5-10 times to be sure. Even a tiny little bubble causes problems.
