I have this popping noise coming anywhere from the passenger side somewhere. It sounds like it could be coming from the passenger seat on forward. It's not the frame/steering box because I keep a close eye on that. I was just wondering what areas I should be focused on when I have someone inside turning the wheel while I'm underneath. I was thinking, springs, spring mounts, body mount, cross member rivits. Also, I just did my front hubs so I know they are tight. I've also check the axle u-bolts, tranny/transfer case mounts and they all seem to be tight. I know others have had this passenger side popping noise ... so what was the solution?
