Two weeks ago my father got his first 4WD vehicle ever, a '99 Suburban K1500 LT with basically every option and 170K miles. The day after he got it I noticed a clickity-clack coming from what I thought was the front-end. Tonight I took it for a drive and listened to the noise a bit more and I think it's coming from the transfer case. It only makes this clickity-clack noise in 2WD. Driving around we also noticed a bit of a roar coming from the transfer case too, especially when coming to a stop. I only listened for the roar in 2WD and didn't leave it in 4WD long enough to notice if it does it while it's engaged as well.
Do these noises point to any common issues? I was hoping to try to diagnose it myself before taking it to a shop.
