IIRC NSK is a different supplier all togther. I have some bearings that are NSK (not the ones we have been talking about) I just looked at the wheel bearings I have here and they are Koyos and Timkens
I would imagine that NSK makes one too. I haven't encountered any.

It's actually 90368-45087-77 and 90368-49084-77 (must have been asleep, I'll correct the earlier post).
These are Koyo bearings.
90080-36067 and 90080-36064 are Timken bearings.
You could use those if you wish. I prefer Koyo bearings.
Do not attempt to "pop" the rear seal in this manner. The rear axle adjusting nut will slam into the outer bearing race and ruin it. I just did mine yesterday, I set the nut in there and it will not clear the race.
IMHO, re-using axle seals is like taking a shower and putting your dirty...
Also replace the axle flange gaskets.
Gaskets, 43422-60040 x 2
W.B. seals, 90311-62002 x2
axle shaft seals 90310-35001 x 2
wheel bearings, 90363-45087-77 x 2 90363-45087-77 x 2
(same as front axle)
The OEM tool is a 09509-25011
CORRECTION: THE BEARINGS SHOULD READ 90368 NOT 90363...
