installed new 4in lift and jeep makes weird vibration sound help?

ok so i just swapped out my 2inch sagged lift for a new 4inch. before i installed the lift the jeep was making a weird noise that sounded like it was coming from the rear end. brought it into the shop and found out the the previous owner has welded the spider gears. had the rear end replaced with a limited slip and the noise was gone. now that i put the lift in the noise has returned. it sound like a strange metallic vibration/rattling. any ideas what it could be?

Prolly a driveline vib, did the lift come with a tranfer case drop? If not you probably need to get either a tc drop, or bite the bullet and buy a sye and cv shaft

i put in the T case drop and brought it to the shop they didn't think its anything to do with the driveline. the noise was there both before and after the lift was installed.
