Yes it will work in your 4-Runner. There is one thing to consider, do you have manual locking hubs? If you do it will bolt right in. If not, then you will need to swap your axle shafts and axle tube bacuse your front axle has an ADD module. This is an easy swap, no seals are broken and you oly have to remove 4 bolts. If you buy the axle I can walk you through the swap. Thanks for the interest!
