- Bearing Caps are trussed.
- Larger Side Bearings
- Side Bearings are Shim Adjusted rather than Threaded-Cap
- More Ring Gear Bolts.
- Extra side rib on the housing of the third itself.
- 10mm housing studs with 14mm nuts (e-locked rears have 8 and 12, respectively)
Those are the main points. The bottom line is that there's just more rigidity built in. If Toyota was smart they'd have designed one of these with an e-locker assembly for the offroad trucks. But they figured the same 25yr old diff was "good enough" despite the extra weight and power of the 2gen.
Just an example of "new Toyota" not being "old Toyota".
It kills me, because the (auto) tranny and transfer cases in these trucks are titan strong. Why those chose to then make the rear axle the weak link just reeks of penny pinching.
