FWIW - I'm pretty sure the Sequoia only comes with the 10.5 rear.
I'm also guessing that the 9.5 vs 9.7 is a matter of gear ratio. The higher ratios have a larger pinion and wider gear face on the ring gear resulting in a slightly larger ring gear OD. I'm not 100% sure on that - but it's the obvious reason for the slight variation. <- that doesn't apply to the 8" vs 8.2 - they are quite a bit different. Although so is a current 9.5 vs older 9.5. A current 8.2 is probably 50% stronger than a 60 series 9.5 and a current 9.5 is probably 100% stronger. Just rough guess, but the pinion updates made a big difference in overall strength.
Even so - the hybrid powertrain has more torque applied to the axle than the 5.7 Tundra or the 5.7 LC200 did. That's a lot for a relatively small axle. And the LC250 is heavy. Heavier than almost all crewcab 4x4 full size domestic trucks except for the raptor, TRX, and ev models. I'm not sure if I'm a skeptic, but I'm definitely interested to see how the 8.2 will hold up. My initial thought is that the software must limit torque in lower gears to help it survive. It's hard to imagine that diff holding up to a full application of 465 ft lbs on a rock climb. I think it would go a lot like the TFL front diff in that video.
