Rear axle slack adjustment

So I have no idea as to what to do with the rear passenger side axle adjustment nut. It is only on that side and do know that is the way Dodge does things.... bang head on wall.... I have read that there should be .018 or so clearance, but how or what side do I measure? I can get the nut side to get nice and snug but the drivers side is still quite loose. Any help would really help. I really wish I had a manual right now. Xmas is coming HaHa, I wish.
I swear I will figure out how to post pics soon.
Thanks y'all

The driver axle butts up against a block in the center of the diff. The right axle also touches this block and the end play of both are adjusted on the right side.

Here's a bunch of info on 8.75 axles

Here's the install adjustment(PDF)

Thank you, the PDF was exactly what I needed. I need to buy a manual.

Ther eare some that love the 'green bearings' so they don't have to deal with this. I prefer the originals.
Also some say that you can run them tighter, as in only a couple thousandths to allow for heat expansion. The factory spec over the years changes even though the materials and construction didn't. So the big thing is to lube the bearings, CAREFULLY install the axle so you don't nick the inner seal, and make sure it's fairly tight and everything is installed.

Like Rod said, definitely be careful with the seals when sliding the axle in, nothing worse than doing a bearing job only to end up having lube leaking out onto the brake! I would replace the seals and gasket every time the axle comes out......I learned this after the fact.  

Yep, don't forget, the inner seal keeps diff lube out of the bearing. The bearing must be packed with grease, just like front bearings. The outer seal keeps the grease in and dirt out.
