In contrast, so are most of the 4 pinions, with ATRAC.
I’ve got one that needed it at ~100k mi (same with my old 80 series). I’ve got another 100 series, with 260k+ miles, on the original starter. I guess it depends on the luck of the draw, and your idea of “life of the vehicle”.
I take it...
98-99 front diffs were 2-pinion from the factory, 00-07 were 4 pinion. Throttle, wheel RPM, and sudden traction probably have more to do with front diff breakage, than ATRAC.
CV axle rebuild is just as bad as a birfield rebuild.
I find the 80 to 100 series weight difference trivial.
The IFS...
Being drawn to a 98-99 pre-VSC/ATRAC, with 2-pinion front differential, because of a perceived weakness in 4-pinion ATRAC vehicles, seems “upside down” to me, but what do I know… If it’s a real concern, add a front locker.
Head gaskets & PHH, vs timing belts & heater T’s.
While the areas of...
I do understand the regret, after going from a 94 LC, to an 04 T4R.
Lusting after the 98-99 rear locker (which also includes the 2-pinion front diff), and whining about ATRAC breaking front diffs, seems “off” to me. Aftermarket lockers do seem to enhance front diff durability.
As someone that...
