Hey guys, my bro-in-law has a 99, 4.0, AW4, 31" all terrains, 3.5" Rusty's lift with 3 degree shim and t-case drop. He has new u-joints on the driveshaft. He has a vibration at around 65 mph. Someone on another forum told him to disconnect the driveshaft and run it at 65 mph in 4-high to see if his vibes were coming from the front driveshaft. I told him the idea scared me but I figured I'd check with you guys first. Any thoughts? Thanks for your time.
