so a little update.... i had hoped this would of been finished today. instead a phone call to advise that my current bearings have been water damaged, and are crap, so they will need to be replaced. good news is the little bearing is a very common part number, and i should have it in 2 days. once the little bearing is fitted, i can get my guys to place it in and check clearance.
i have a jn15 vzr gearbox, and when my guys pulled the big bearing off, it was the same number is members's "bhowle" one. so for those putting one in after me, some important numbers are...
31408-31X08 Big bearing (for lhs)
38440-D2100 Small bearing (for rhs)
38342-8E001 Axle seal (little axle seal)
38342-8E002 Axle seal (big axle seal)
now the seals and little bearing you should pick up no problem, the big one could be a problem, but is currently available for amayama trading via nissan japan.
one thing noted is the alignment holes (for mine) aren't spot on, but they will be for yours, and really it doesn't matter anyway, so long as the bolt holes are fine, which they are. below is a photo of the helical underneath the oem viscious.
