Popping noise from rear end

I would check out the universal joints. Crawl under the vehicle and see if there is any play in them by trying to move around the drive shaft. If there is excessive play then the u joints are the problem. Hope this helps and good luck.

HAve you changed the fluid???? Is it a limited slip rear end? Those require special fluid and an additive. If not correct rear end clutches can chatter and make noises too!
