Trans Diagnosing shaking while driving-possibly flywheel

[Scout1067]

I think I figured out my issue. My jeep shakes like a terrier when the clutch is engaged and I am engine braking or when I am accelerating. If the clutch is engaged but I am just coasting the shaking stops. I have eliminated the driveshafts as the problem and all the wheels are newly balanced so that leaves me with the thought that the flywheel is off balance. I also get some clutch chatter when I start in first gear. The only thing I can think of is flywheel, or does anybody else have thoughts on what it might be?

How are your motor mounts?

Is the clutch slipping?

Doesn't slip, just chatters when I let off the clutch in first

I think they are the original mounts. It doesn't shake when sitting still idling, only when I have the clutch engaged and the engine under load. That is why I tend to think it's the flywheel. I didn't replace or have the flywheel turned the last time I put a new clutch plate on but that was 2 1/2 years ago and this issue just started last week.

I had a similar problem loooong time ago o a 70 challenger. When I backed off in gear shook the whole driveline. Motor mounts are easier than flywheel.

I will probably do both at the same time, motor mounts and flywheel since I have both on my PLL shelf

Doing both at the same time , you won't know what the problem is.

True, but if it fixes the issue I am giving serious thought to selling my jeep afterwards

If you must sell it do find another.

Well, while waiting for parts, I decided to pull off the inspection plate on the bell housing. The teeth are freshly worn along about a quarter of the circumference of tje flywheel

Do you have an update for your issue…

 

[Scout1067]

It turned out to in fact be the rear drive shaft. It felt tight and no play while on the vehicle but the rear u-joint fell apart when I took it off getting ready to pull the transmission.
