Vibration upon letting off gas

Hey guys. I have been driving the GC as often as possible. There seems to be an annoying vibration when you lift off the gas pedal. Doesnt seem to matter how slow or fast, You can feel it in your seat, not in the pedals. Anybody have any ideas? TIA Shawn

I'm gonna say the driveshaft needs to be balanced.

Mine does the same and that's the cause.

When u-joints go bad on the driveshafts they will cause that as well, I would check those before actually removing it and taking it to get it balanced.

No harm in removing the front driveshaft for a quick test drive. At least it is the active action rather then a passive one.

Yeah, that's a good idea, it takes all of 5 min to do and if it fixes the vibration you know where your problem is.
