Default diff. pegging and diff reassembly

so I had my 3rds out and took the front differential apart. so putting it back together, wondering....how much pressure is supposed to be on the gear. I didn't adjust the peg. I just slid the assembly to it before securing. should I do more? maybe tighten peg then back off X amount of turn?

You should talk to Bill at GBR.

Actually talked to him today (ordered a new front dshaft) I conveniently failed to mention that I disassembled the diff he built me because I thought it was broken.
When it was an entirely different issue

You have any pictures of how the pegged diff looks inside? Wondering how the GBR method compares to the Ashcroft method?

I think so.
I will look. If i don't have a picture I can take one, as I still have the front diff out.
It is just a looks like a big huge bung with a nut and a big huge bolt with softer peg fitted, to the inside. Centered at about 7/16 - 3/8 of an inch from the edge of the back of the ring gear. I will get you a picture

A pic would be sweet. They use some sort of bronze pad? I should have pegged mine when I rebuilt the diffs last year. I might just buy a couple housings from GBR.

so to recap.
1. get your backlash and preload correct, while putting it together.
2. set caps in place, snug locktited bolts
3. as per rave 66ftlbs on the 4 bolts, criss cross pattern. (I like to torque -10ftlbs, then -5 ftlbs, then final)
4. tighten peg to close encounter (like a whisper, not a yell.....just a hint of drag) with ring gear.
5. back the peg off 1/3 of a flat of bolt head. (this put me 100% back where I started)


a little goop, tighten 10 little bolts and vrum vrummm
