nissan motorsports 4.6 final drive questions

[sdtouge]

im getting a deft force soon, and at the same time i was planning on installing the nissan motorsports final drive (4.6 one)
for the bearings in the gear and pinion part in the back of the diff, is it neccesary to replace them? when replacing the final drive? there are two of htem and each one is 100$, so that would make this like a 1600$ lsd....


thanks for the help

It's not required but it's a good idea to thoroughly inspect for wear or runout and replace them if they look suspicious.

i would recommend replacing them
highly recommend
why do the ring/pinion swap 1/2 assed? get new parts with your new diff and you wont worry.

i did for mine
its cheaper thru dealer usually
