Servicing your differential: Suggested rebuild kits

[AKADriver]

Even paying someone else to do it, might as well get the best parts. Diff shops aren't going to be like normal mechanics who refuse customer parts, considering you're already bringing them your housing, carrier, and R&P.

Anyway the OEM parts are

Diff Side Bearing (38440-N3110) (need 2) = NSK R45-11-A-SA U42, Koyo HC 57160LFT

Side Shaft Oil Seals (38342-N3100) (need 2)

Front Pinion Shaft Bearing (38120-13201 or 38140-V7000) = NSK 32306AN

Rear Pinion Shaft Bearing (38120-61000 for '89-'96) = Koyo TR07081R, NTN HR32307CN / (38120-10V00 for kouki S14) = NSK R35-24 NU42 (This bearing is 38mm thick, the older variant is 32.75. some say the kouki inner bearing fits all)

Pinion Shaft Oil Seal (38189-N3112)

Rear Diff Housing Gasket (38320-40F02)

You can probably find OEM grade non-Nissan equivalents to all of these if you search by each PN. From Nissan USA the bearings are silly expensive. I think the bearing equivalents I listed are correct but triple check. If you take apart your old unit yourself you should be able to find the supplier part numbers on the bearing outer races themselves.

Thank you for the PN!!!

So I built a cart using Nissanparts deal and the total came out to over $700...

Doing it on Rockauto (National, SKF and Timken brand parts)came out to less than $250 shipped...

But you know the whole saying, you get what you pay for I am tempted to go with NPD.
