2002 Jeep Grand Cherokee. When letting off gas I feel a strong vibration (slight vibration when maintaing speed) in the front of vehichle. Any ideas on what is causing this?

I would have a 4WD specialist check all the universal joints in the drive-train…One could be loose…

yep definitely. I had a u joint go out on me one time and it shook when i decelerated and not when i was giving gas. climb underneath and check the drivelines and axle shafts. they all have u joints on them if its a 4x4. when you grab the drive lines and twist them back and forth. you should have zero play in any of the joints. if you do then the ones with play in them need replaced.
