2002 Jeep GC making loud noise when I let off the gas.

Hi all,
I am new here and looking for some help. I just bought a 2002 Jeep GC 4.7 Quadratic.
When driving it makes a loud roaring sound from the front end(I think) when I let off the gas. while under load on the gas no noise.
Any clue of what I should be checking first?
Thanks,

Welcome to the garage.
Does the noise change with reducing speed? Could be a pinion bearing inside the front differential. I would check the fluid of the differential for metal chavings. Also check the prop shaft joints for play.

Thank you. It is louder the faster you are going when you let off the gas. The fronf shaft seems tight u joints all look good.
