Noise when shifting into drive

[SavageC20]

Sometimes when I shift my truck into drive and then let off the brake and give it a little gas to move forward I hear a loud clunking noise, almost like a ding. It seems to be coming from the rear end. Once it makes the noise it will not do it again until I stop and put it in park and then drive and take off again. It is an intermittent issue. I have the original Dana 60 in the truck. Has anyone else come across this issue?
