I think I typed this before but in all these posts it's easy to miss things. I used a stock open diff axle (actually multiple ones since I've torn the CV boots on them) on the passenger side for my 5th gen AE A33 LSD 5spd transmission swap in my 4th gen car.
There is no difference between the AE LSD and the 1997+ I30t LSD transmission according to the FSM. In 1997 Nissan changed from using a single baulk ring on the 1st gear synchro to a double baulk ring on the 1st gear synchro, this doesn't affect anything to do with this swap though so don't worry about that.
There is no difference between AE LSD and I30t LSD axles dimensionally.
Now that I work at a performance transmission shop I am going to hopefully be able to do a Rockwell hardness test on the gears of both my AE LSD transmission and whatever other maxima transmissions I can get ahold of (I currently have a blown open diff 95-96 transmission to compare to) so that I can
A couple points, to make it easy for people to see them:
- When swapping from open diff to LSD, you ONLY need to use an LSD driver's side axle. The open diff passenger side axle works in the LSD transmission.
- AE LSD or I30t LSD axles may be used interchangeably, they are the same (you still need to make sure you get an ABS ring if you have ABS on your car)
- The 3rd gear on the 5th gen (A33 trans) is dimensionally NO DIFFERENT from the 3rd gear on the 4th gen transmission. This indicates a high probability that the 5th gen gear is no stronger than the 4th gen gear, but does not prove it without a doubt without having done a Rockwell hardness test on both gears. I will be attempting to do this over the winter (see above). It is however my belief that Nissan made no changes to the 3rd gear manufacturing process, and I believe the gears to be identical between the two generations.
