vibration/shaking under power only

my jeep has developed a terrible shake when under power, it continues through all gears. if i press the clutch in it smoothes out immediatley. so, clutch, tranny, mounts etc... where should i start first, what is my most likely problem?

bad u-joint? Could possibly be a bad mount, letting the driveline angles get out of whack I guess...but I would think that would just get you a noticible clunk when you first start moving in gear and not a continous vibration...

yall were right. i have a tom woods double cardan drive shaft in the rear and one of my gold seal u-joint caps was completley gone, the metal under the cap was whittled down to a point almost. the problem is that there is also some damage from metal to metal contact on the knuckel were the two u-joints fit in the double cardan. i think this might be covered by the tom woods warranty when one of their u-joints goes out. i'll call them tomarrow to find out.

If you destroyed a u-joint in the CV assembly, something is seriously wrong! I've been running the same 1310 Tom Woods CV system in my rear D-shaft with zero issues in the past 9 years! Its still tight the day I got it. Im only tearing out the u-joint at the rear axle which is normal. But tearing out a joint in the CV system And Im packing some serious torque in my drivetrain. something is wrong. Better check your drivetrain angles and all your mounts. Even the motor mounts. A bad motor mount can cause drivetrain to go 3 sheets to the wind.

Tear it apart and inspect the centering ball also...fair chance it's gotten boogered up with that much damage.
