2002 F-350 Rear End Specs?

[tysonmatc2]

I tore into my rear end last night because I found some metal chunks and found that the shim on the Pinion Gear shaft was torn to peaces, the bearing spun on the shaft and I believe the shaft is shot. What are the backlash specs for a 3.73 rear end? I was thinking between .008 to .015 but not sure. Any help is appreciated, thanks!
