diff poping when turning left???

Today I was hualing a mini track hoe with my 86 F-350 dually, like I normaly do from time to time, and encountered a horrible poping noise when turning left. Turning right, under load or not is fine. Turning left under load is the only way it happens. I can coast left not under load and be fine. I dropped the trailer and it still does it.

under load = using the gas
not under load = coasting

Any ideas what this could be? Anybody else have this problem.

Thanks

Is this 4x4? Can you isolate the noise a little more by having someone listen from the outside while you drive it?

could be a bad bearing as the bearing and the retainer hold the axle in when turning

Okay, didn't wait untill morning. I jacked it up and pulled the axles. Both outer bearings look great. I took the diff cover off and no obvious shavings or anything in the oil. I'm not too sure what I should be looking at in there to be honest. I'm tempted to take the diff out but then what?

Just a recap, it only "pops" when turning left and you have it under load. Any amount of throttle will make it pop and if I push in the clutch it won't do it. Does not do it when turning right.

Thanks

UPDATE:

I took the differential out and all the bearings and gears look great but the steel and friction plates are TOAST! There's grove marks in them.

It was the limited slip clutch pack.
