I am swapping the TII diff into my FD for hard launches. The mileage on the diff i got it unknown, so i figure i should replace the berings inside there since its out. Anyone have any other suggestions as to what i want to do to get the TII diff prepped and does anyone have any idea what part number the bering is??

 

make sure it's an S4 diff instead of an S5. Otherwise, in l33t speak, it is teh sux0rs! Might want to change the ring and pinion gear as well. Though, you'll definitely need to replace everything in the diff if you do that.

(S4's came with a clutch-type, which is want you want, S5's came with a viscous-type)
