Unless I am completely misunderstanding something here...

I just installed my aussie locker. The Aussie installation booklet told me to torque the 8 bolts holding the case together at 50 ft lbs. The FSM says to 35 ft lbs. The FSM is 1988 specific. But it has diagrams for both the 2 pinion(4cyl?) and 4 pinion(6cyl?). But where is has the torque specs for those 8 case bolts, it does not say for which diff. I swapped in v6 diffs into my rig, and that is what I bought aussie for also.

I torqued them to 50.

Any input?

Also, I might just end up taking it to someone because I did not mark the bearing caps, and I would not even know where to start on how to set the back lash and stuff....poop on my parade

 

If you didn't change the gears you shouldn't have to set any backlash or anything. When I did mine all I did was pull out the spider gears and install the Aussie as per the specs that came with it. Have you looked at the installs over at Zuks site?

 

I'm working on one right now....Aussie into V6 4 pinion case. I noticed that also....aussie says 50 and fsm says 35. I am figuring that because of the increased strain of an aussie trying to push the casings apart that they wanted to see better clamping pressures on the bolts. I did some testing by marking the factory bolts with a dremel tool with mini cutting wheel on it. I placed a grind mark on the corner of the bolt and then loosened and re-torqued it to the same grind mark....it was way over 35 and that's from the factory. I like to use 45 myself.

 

thanks both for the replies and help. After reading a little more, and reading a couple of your write ups. I guess the 4 cyl diff doesn't split like the 6 cyl diff. So that answers one of my questions. . thanks
