Rear wheel bearing adjustment on 2007 Chevrolet Silverado 3500 HD

The rear axle nut is locked in place with a key and snap ring. I snugged the nut up until all play was removed and then backed off the nut to the first key way alignment. I am looking for a posted, proper adjustment.

Autozone have some popular workshop manuals for free on line once you register (for free) on their website There is also a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
You'll like Alldata if your do work on your own car.
Thanks in advance, I will check the sites. I do like to work on my own pick-up but to date I have been unable to locate anything short of a $250 set of factory shop manuals. I have the crew cab, 8 foot bed, diesel engine and duel rear wheels. The diesel is the problem. Each quiry I make for CD or repair manual, the results indicates "doesn't include diesel". AllData sounds like a site I have already been on with no avail. If you know of any source for repair information, please advise me.
