I blew my Ring gear

That was a nasty noise hearing that third break! lol! I quickly took the bypass after that!

Hey here is another 3rd I found. It isn't close to me, but maybe someone else can get it for you. Toyota v6 3rd member

It's cool man, turns out a friend had a 4.10 R&P laying around and a local guy is going to set it up for me. Gotta love the off-roading network of friends willing to help. Thanks man, I appreciate you looking out for me.

I don't blame you dude, which my first impression would have been more impressive. The last time I did wildcat, it was no problemo.. In reading, and asking.. I have a good idea why my Ring gear failed my twice. I think there was too much deflection under load because it happened when I was climbing an obstacle on both occasions. The first time, it knocked out one tooth and the second.. all of them almost. Probably because I kept backing up and trying the same obstable despite the noise.

Torquing the adjusters after locker install would have probably prevented this. I returned the adjusters to the same marked position, but didn't even check how tight it was or rolling resistance of the carrier. Interestingly, I have read that the 8" toyota diff has a history of this weakness in deflection which is why they went to 8.4" diff on the Tacoma/T100/Tundra model.

The Tacoma/T100/Tundra model has several upgrades from the older 8” including a larger pinion shank diameter and main-bearing cap girdle (see above picture), which reduces deflection (deflection is a leading cause of ring & pinion failure). Source

Most people are reluctant to really crank down on the side adjusters in their differential. Attaining a good preload through the side adjusters can be critical in protecting your differential from the high torque loads that cause ring gear deflection. It is not uncommon to torque side adjusters to 150-200 ft/lbs when setting up a differential. Source
