Shake when letting out the clutch

I have a 1979 CJ7 with the 304 and a 3 speed transmission. I have an issue with the jeep shaking/jerking when letting out on the clutch only after it warms up. When this happens I can sometimes press the clutch pedal in and rev the engine and it works perfect at that moment but the next stop I am right back to the same problem. It feels like the Jeep is going to stall but the shaking/jerking is enough to bounce the vehicle. Has anyone experienced this and found a solution to their problem?

Clutch Chatter. My 76 CJ5 did this. Its one or more of the following: worn out clutch assembly, improperly worn clutch assembly, bad transmission mount/torque stud bushing, or worn motor mounts. In my case it was all the above. Replaced all of it, no more chatter.

you may have an oil leak somewhere (valve cover, rms maybe) causing the clutch disc to get oil on it. At least that's what I found when my clutch was doing the same thing; chatter when warmed up, works fine when first driving.

Also include bad/broken body mounts.

Start by trying to lift the body at mounts forward of the t case. Pay close attention to the body around the clutch linkage.
Lift the engine slightly by the pan and see if one of the motor mounts separates.
Remove and inspect the transmission mounts.
Insure the skid plate is tight.
Insure the clutch linkage is operating properly.

Repair any discrepancies.

If all is good, then you have a clutch issue.
Disassemble the clutch. Hot spots on the flywheel and pressure plate are signs of riding the clutch and can cause jutter.
Insure there is no on contamination (oil) on the assembly. If so, you will need to fix the leak.

While you can inspect the rest of the components, I would simply replace the assembly, being sure to turn the flywheel.

Paperwork will ruin any military force.

I had the same issue, thought it was the clutch but turned out the bolts holding the tranny to bell housing was loose.
It allowed the tranny to become a little tilted and chatter.

Have you been yanking and snatching you Jeep----burning the clutch/ flywheel/ pressure plate, as in pulling a big truck out of a ditch or attempting to pull a tree/ bush out of the yard for Mama?

You might check the clutch linkage. That bellcrank lever that goes between the clutch pedal and the throwout lever is pretty wimpy. I've had to replace mine twice in the last 20 years.
