Ring gear backlash: I see the .006 backlash and the method to get it, but what is the final torque spec of the adjusters? I saw 75 ft/lbs somewhere and wondered how that was accomplished. Some sort of 2.5 inch socket that has some teeth ground out of the walls? I see the adjuster pliers but there is no way to measure torque on those, Look like ring spreaders with pins on the end.
 
75 ft. lbs is not the torque of the side bearing adjusters. If you torqued them that tight you'd never turn the differential. That is the torque figure for torquing the bearing caps. For the adjusters you just need to pre-load the side bearings with the adjusters just like you do wheel bearings. I tighten them down fairly tight at first and turn the differential a couple revolutions to make sure the bearings are seated in place then back them off until there's just a little resistance to turning the diff. Then you torque down the bearing caps to 75 ft. lbs.
 
Thanks. I saw this but cant find it again. If its not called out anywhere that I can easily find, it must be a "set backlash and snug + umph" method as shown in the carcraft article.
 
Fishy, found something better. Read Deans post here: 75 ft/lbs...http://board.moparts.org/ubbthreads/showflat.php?Cat=0&Number=6907425&page=0&vc=1#Post6907425

MoparMuscle article is here, Car Craft article (http://www.carcraft.com/techarticles/ccrp_1006_mopar_83_4_inch_rear_axle_assembly/viewall.html) was worse: "Starting with a large amount of backlash, turn the left adjuster (opposite side of thegear teeth) as tight as you can, pulling on a 12-inch long spannerwrench. Tighten the right-side adjuster to make sure it's tight, andthen measure the backlash. Randy's Ring and Pinion recommends .006-.010inch of final backlash, easily checked with a dial indicator. Backlashshould be checked at four different positions by rotating the ring andpinion. If the backlash is too wide, back the right (ring-tooth side)adjuster off a notch, and then bring the left back in to full preload.Again, wrench the right adjuster to make sure it's tight, and recheck.Work the ring gear toward the pinion in this manner until the backlashis within specs.

Ok. I don't have an adapter for my torque wrench to see just how much I'm getting them torqued to but maybe it's more than I think. I haven't had any come loose or cause problems and one I did is running in a buddies mid 10 sec. race car so I must be doing something right, LOL

When I heal up from back surgery and I'm able to do one again I think I'll make an adapter for my torque wrench to see just how much torque I am applying.
