Vibration while under torque

2006 Wrangler 2.4L, 114k miles

While driving, only in 2WD and 4HI, I have a bad vibration around 1800-2300 RPM. I am replacing clutch/pressure plate/associated bearings this weekend. If stationary and holding same RPM range, I am not getting the same vibration. While moving, if I push in clutch pedal, the vibration goes away. I have crawled underneath and tried moving driveshafts and everything seems fine there. It is really driving me nuts, what else should I look at?

Pull the drive shafts and check the u-joints.

Off and On, I have had the same issue. For me, every time it has happened, it is in relation to one of the driveshafts. There are a few parts that can go bad, u-joints, centering ball, or splines themselves. Start with removing your rear driveshaft. put it in 4WD and take it for a drive. If the vibration is gone, it will be the shaft. vise-versa for the front. It could be something in the axle like a pinion bearing, but from what I read, those make a deep growling sound in addition to vibrations.

I'm willing to bet that you have a stock rear drive shaft and a couple inches of lift. Your problem sounds like a textbook example of a drive shaft shudder/vibration caused by too much angle on the stock rear drive shaft. I'm not sure if you have a Rubicon or a standard TJ. Either way, I think that a double cardan (CV) style rear drive shaft is the solution. If you have a Rubicon model, it is as simple as replacing the drive shaft and adjusting your rear control arms. If you have a non-rubicon model, you will need to do a slip yoke eliminator kit.

Was the drive shaft removed or disassembled prior to the vibration? If it was removed and the yokes are not aligned properly, there will be vibration.

I'd echo the advice to check your u-joints and add checking for a loose t-case or differential yoke.

Just had the same issue with my '05 TJ.
Got a new one with a grease fitting.
Be sure to orient the new u-joint so the fitting is accessible......
There is a 'backwards' install where the grease gun can't fit on the zerk.
Been there, done that.

Vibration under load is a warning =)
