Busted 2 teeth off the rear pinion gear today

Apparently BrenSpeed is the same. My shipping on the gears was free, and they are not the "blue box" Motives but the steet performance gears which are more accurate and better hardened. Mark also mentioned Reider as a good source and I'll consider them also in the future...although I don't want to bust another set just to try the vendor, lol.
Well, they tell me they'll be here by Friday without expedited shipping. They're helpful at BrenSpeed when you call so I can't fault them there.

No, Zach. Brand new 2-3 ysars ago when I put them in. I'll post what I find during the teardown -- anything's possible. I won't be doing it now until the weekend though. I did have OTHER things planned to work on this weekend, but this obviously takes precedence, lol.
Brenspeed is still cheaper, Rob. I got what you're talking about for $243. Just write or call them and see what they say. That's the basics.
Are you doing this yourself? Do you have the tools you need? The main thing is an appropriate press to remove/install the bearings, a beam-type (non-"clicker") torque wrench that reads to 20 or 50 inch-pounds, and a dial indicator with a magnetic base. A micrometer is sometimes helpful as well to sort the shims when you need to.

What I ended up doing is buying the 4:56's from Brenspeed but I bought the install kit for motive gears off jawgears.com
They said something about needing a special notched cross pin or cross shaft? Can I buy this seperately somewhere? I don't think it came with the install kit from jawgears.com :(

I'm pretty sure Alon will lend you a hand, try PMing him alon@modbargins.com is his name on here.

I have no idea how to install these and I'm currently looking for someone in the SoCal area that could be of assistance. I'll pay you too :] PM me if anyone's interested in lending a hand.

actually with 4.56s (8.8) it does not take much grinding on the ring gear to get it in there

I agree. I notched/flatted my cross pin and all it got me in the long run was a worn cross pin hole, lol. It depends on your diff as to where you "notch" it -- but it'll be overall stronger if you just grind a bit off a tooth of the gear.
On a really thick ring gear (4.88 maybe or 5.13 for sure) this isn't practical, but it's not a lot of metal on the 4.56. I'm doing that this time. Auburn is sending me a new cross pin for my ECTED and I'll be putting that in this weekend.

Ha ha, maybe so -- but at least my truck has a "real" Dana 44 up front -- not a tarted up D30 with a different center section...[ducks down behind cover]

It would be better to my peace of mind if there were something I could put my finger on other than my foot-to-the-floor offroading style that was necessitated by being 2WD when everyone else if 4WD.
I broke a set of Richmond 4.10's in a similar manor as you have.. Was just driving along.. and ( insert noisey sounds here ) started.
Sometimes stuff just ' breaks '.
Usually, it takes a big engine to break stuff like this. My 3.0 should be proud, lol.
I bought Motive Gear stuff this time, the "Performance Line" or whatever it's called. Much better than the low end Yukons I bought last time. Yukons top end stuff is very very good and their junk is good -- for junk.
But every time I cut corners with what I buy, I regret it. This is just one more thing I did years ago that I wish I'd done differently.
Remember that water pump I ditched in Centrallia? I lost a cobra wheel.. Umm, how many tbars snapped? Balljoints..
We all become edumakated sumtyme :)

Ha ha! Yes, well us experimental and aggressive types do break stuff don't we? And then there's the "routine" or just "random" failures. Thanks for the encouragement -- but I'm not real down about it. Just annoyed at *another* repair job, lol. I could be spending this time finishing the build up instead.
They were new gears, didn't magnaflux them and probably won't the Motives. It's probably a good idea to though. I just have this idea that it shouldn't be such a deal in such a low powered vehicle, lol.
Learning by experience is what it's all about. In the process of "overcoming" you become more capable. That's most of how you and people like you who are my role models for "automotive self sufficiency" became as capable as you have: overcoming difficulties of one type or another.
Yes, I'm getting more experienced -- dang it!

As John works on his next experimental project utilizing direct drive Traction Motors powered by a Mr. Fusion Home Energy Reactor he picked up at a Defense Reutilization and Marketing Facility

Mate.. we need a drink ( LOL! )! Mocca or Hot Chocolate?

All better now. Took it apart and found the pinion busted off THREE teeth. I'll photograph it later and post it. Nasty.
All three teeth ended up somewhere where they didn't hurt anything, praise God!!!
I took my time, cleaned it out good, replaced bearings and races, etc. The new center pin from Auburn took all the slop out of the differential inside also. After fully cleaning it, there was no scoring if the spider gears, or even the ring gear.
Three other mechanics at work examined this and said it looks like the pinion gear just gave up the ghost. There was no wear or funny marks on the ring to show that any long term weirdness was going on.
I guessed a pinion shim of 0.032 for the new Motive Performance Series gears and it turned out to be right (another blessing). The shimming of the carrier for lash is trivial.
I spent a lot of time though setting up there at work where I had the truck as there were none of my little jigs for pulling gears there, though the press was there. A lot of time cleaning things up also. All told I spent about 7 hours at work today doing the axle rebuild.
But it was by the book and everything is right now. Very quiet on the way home except for chatter on turns after awhile. There as no limited slip additive at work and I had to use straight 80W90 gear oil. I'll be draining this in a week anyway after break-in so I'll add some when I put the "final" oil in the gearbox.
It's was real good to find the ECTED had not been damaged. Whew!
Also, the diff was scarcely warm to the touch, though it has rained so there was some cooling effect. Still, no real heat I don't think.

Plan is sometime in the next 3 to 4 weeks. I just ordered what I need to rebuild the double cardan in my front driveshaft. I have the rear and the u-joints already.
Nothings stopping me but time to work on it at this point. I want to take a couple of days off from work but with the acquisition by Evraz Oregon Steel and all the changes they want I'm busier than I can adequately describe, lol. Our entire financial and production reporting system is being revamped.
