Not sure what kind of disconnects you have, but that doesn't sound good. Like anything else that doesn't move, it's either rust or lack of effort... I know on the first lift I put on in 03 I had a popping noise the day after and thought it was the disconnects until I saw the paint peeled up on the swaybar where it meets the frame/front bumper on the drivers side and clean metal on the other. It was just the sway bar moving. It stopped after it settled. I'm a fan of Arocroil (probably spelled wrong) and that fixed it. Once it got settled I had no more noise. I just replaced the P.O.S. Superlift springs with Old Man Emu after 80,000 miles on the Superlift and went through the same thing again. Take a look or measure the difference on each side, that might be it. If it is it will stop. If not, keep looking, may be driveline issues. Oil stuff up, and keep driving, you'll figure it out. Nothing beats having someone you trust ( or your wife) driving it while you watch and listen... Either way, I think I'd replace that disco.
