97 F450 F-superduty rear end problems

[ITRalex]

Hi everyone,

I have a 97 F450 Dually with the 10 lug rear end (Dana 80?)

recently, my rear end has been acting up. it makes a popping noise once in a while and the level of the noise increases as I have more weight on the truck.
its not a constant pop pop. its just one pop and the truck jumps

The noise happens when I am accelerating and when the pop happens the rear end of the truck jumps to the left and then it would be fine.

I am wondering whats going with that and if other people have experienced the same problem with theirs


Thanks
