Haha I love it. Is the shwagin wagon on air?

Ok guys on another note. I am having a little problem. Last September or do I swapped out my one legged 3.73 gear set for a 3.07 posi. Well everything has been good since then but now once the rear end warms up a little I get a popping from the diff. I added 2 of the posi lube additives when I filled it after the install. I'm thinking about draining the fluid an just straight Lucas gear oil. It says on the bottle that you can use on posi units with no additive. What's your guys thoughts?
