    Maybe after a time driving, the engine heat is transferring to your mounts and softening them? :shrug:

    The solution might just be your engine/motor mounts. This is new knowledge for me, but they are a wear item and have to be replaced regularly on lesser automobiles, sometimes within 20,000 miles or a few years, depending on how hard you drive...and especially on manual transmission vehicles.

    Think that is the issue. I did not resurface it.

    I have never resurfaced a flywheel. Seems like other things might be more likely, IMHO.

    Maybe take the word of someone who has had dozens of these Jeeps and attach a stay cable. Just might be an idea worth trying.

    My money is on either a non-flat flywheel or oil contamination. If you seperate the clutch, I'll bet you'll either find discoloration, micro-cracks or small sludge smears on the surface of your flywheel and/or pressure plate. I'd be willing to bet the seal on the input shaft of your transmission leaked a little bit (maybe you parked on a steep downhill?). This will drip right on your clutch disc, and centrifugal force will sling it out to the mating surfaces. If the inside of the front bearing retainer is wet when you pull the trans, you may have found your culprit. Make sure you replace the seal, and don't overfill the trans.

    If it was fine before and now it's not, something obviously changed.

    Look for blueish, hot spots on flywheel?
    And I hate to admit this, but I've taken them out
    with a DA sander and some 40_60 gt paper!
    Much better to visit a mach shop Though!

    Juffer the stay cable is factory original on V6. My 66 Tux came with one.

    Mine did it when backing up hill. The zero dollar fix was to shift into low range when backing up. Gets the clutch out right away, no chatter.

    Make something. A lot easier to try than pulling the transmission and so on.

    Should be able to make one pretty easy. The cross-member should have 2 small ears sticking up on top of cross-member that the ball end of cable sets in. Other end (threaded) bolts to bracket mounted to bell-housing to engine bolt.

    On my 17th birthday I purchased a brand new 1968 CJ5 with V6 off a dealers lot in British Columbia. After owning it for about 2 months, the engine started to shake violently anytime you tried to back up. The engine shook from side to side so hard that you could not keep your foot on the clutch pedal. Since it was under warranty I took it back to the Jeep dealer for repair. My assumption was that I had broken an engine mount. The dealer indicated there was nothing wrong with the engine mounts and this problem was not uncommon on CJ5's with the V6. The factory solution provided by Kaiser was for the dealer to instal an anti vibration kit. The kit consisted of two brackets and a hydraulic dampener, like you would use on your steering arm. One bracket mounted on the top of the engine and the other bracket mounted on the inner fender on the drivers side. The damper prevented the engine from rocking easily side to side. I was less than impressed with the fix, as it looked a bit strange, but I never had another problem with the engine shaking when in reverse.
