So I managed to change out most of the fluids in my G35x (rear diff, transfer case, oil, atf, brakes, etc), but the front diff is baffling me. There just isn't enough room to maneuver. I can get by 10mm hex on the filler slot but then I can't move it at all. The bottom drain plug is bad but not as bad as the top. What tools did you guys use to do this job? I doubt any torque wrench could fit up there either in the event that I was able to get that filler plug off.

 

I used the same hex driver that worked on the rear caps. I just stacked up a couple of extensions on my 3/8 drive ratchet to bring the tool out to where I had room to swing it. Just make sure you keep the hex square in the cap so you don't round off anything. It was a pain to break them free but after that it was a piece of cake. I got new plugs(caps) and washers from the dealer because mine were so rusted I didn't want to use them again.

 

Do you have the part numbers for the front drain and fill plugs?

 

The drain plug has a magnet. Part # 32103-1MGOA. The fill plug is 32103-1MGOB, no magnet.
The gaskets are #11026-4N200.

 

Got a link to somewhere that carries these? Searching those part numbers on infinitipartsusa, everythingnissan, courtesyparts, yields no results except for the gasket.

Thank you

 

Try 32103-1MG0A and 32103-1M0B. The zeros look like O's. I took the numbers off the labels that said Genuine Nissan Parts.

 

Thank you much Bassman. You were correct, 2 different extensions purchased at Harbor Freight was all I needed. Changed the fluid out this evening. I was surprised that only .8Qts went back in. Was expecting more fluid it's all good.

 

The front diff. doesn'y take much oil. 0.8 qt sounds right.
