since I swapped in a montero LSD I'm going to get the axles redrilled. I originally was looking for a toyota axle, but they did not come stock with a LSD and a TRD LSD was pricey. I got my montero LSD for $45 a the local u-pull and was also able to swap some 3.54 gears for a better mpg. A explorer axle with disc brakes would be nice, but the stock brakes have been sufficient.
