Driveline Vibration
I am getting a weird driveline vibration and im trying to diagnose it. i would like some help
Jeep:
2000 LP30/8.25
4.5" lift, 32s (no SYE)
Symptoms:
The vibration is from 58-67 mph. Anything higher or lower i feel nothing. it is also ONLY when i am on the gas, when i let off, it goes away.
the front driveshaft u joint has a little bit of play in it, but the part that bugs me about it so much is that its only from about 58-67
any suggestions would be greatly appreciated

I have the same problem. I removed my front shaft and all the same, removed rear shaft and problem went away. Replaced u joints and no luck, I am going with a sye. Just put my lift on and its only three inch but I have a 2000, which have problems.
Try removing the front driveshaft and drive it.

vibrations that go away on deccel are bad U-joints.
stress on Drive shaft is taken away on deccel causing the caps to stop moving on the trunnions. bearing surfaces are most likely brinelled or needle bearings are toast.
