I've been smelling gear oil so I thought I would climb under the truck and check things out. My rear passenger side brake cover is soaked and the rear differential fluid is low. I've done the job before on my old Wrangler but don't think I want to put myself through that again. My question is if/when I pay someone to change the seal should I have the do both? I know on my Jeep I had to remove both axle shafts so it was just as well to replace both.

I did both mine a while ago, it's possible to do just one. Your call. If you haven't done the axle vent mod I'd recommend it unless you want to keep replacing seals.

First I've heard of it, I will definitely look into that mod

If you have a 2005-10 model, you should read Nissan technical service bulletin NTB10-008. You can download it from here:

Changing both would probably be good practice. Does the other side appear to be wet? Did you check out your axle breather? Does it appear to be plugged up? This is important to replace and or do the axle vent mod. Otherwise you are just going to have it happen again.

The bearings must be done to replace the seals and the parking shoes get oil soaked too.

That's not good, so seals bearings and brakes for both sides. The axle vent looks fine, the cap moves around freely. I don't take the truck off road so I'm not even sure the vent mod is necessary for me.

My drive side seal started leaking about a year ago. I regularly check my vent to make sure it is not clogged. After seeing the leak I pull the stock vent and vented it with a hose. Bought all the parts to get ready to replace the seal. Look about a month later and the seal stopped leaking.

How can I get a copy of the NTB.

My truck never goes off road. I knew the passenger side was leaking but pulled the driver side apart just because I had over 100,000 miles on the truck was already disassembled, I was very surprised to see that the driver side was no good as well. My axle vent rotated freely but I changed it and put a new one in for $13 why not.

I think it has something to do with the OEM vent design. Not only does my vent spin, the top moves up and down. I have even removed it and blew (or sucked) through it. Every indication seemed that it was working fine. But once I used a hose to vent my axles the seals stopped leaking. Maybe it was a coincidence. But I think the OEM vent causes seal issues.

All axles need to be vented. It is not an offroad thing. It is an expansion of gases and fluids thing.

I just figured the factory vent was okay if you stay out of the mud. I may go buy the stuff tomorrow

Please be advised, many have done the vent mod and ended up with blown seals. Its a design issue, a plugged vent just seems to speed up the seals failure.

After replacing a leaking driver side, 10k miles later, my passenger side is still in good condition. No leaks. I say fix it when it's needed.

I vented the axle and thought that fixed the leak but every once in a while I get a whiff of gear oil coming from around the rear wheel. I'm looking on here as well as some part suplyers and it seems I'm coming up with different parts. Can anyone tell me if these are the right parts for my 2011 SV 4 door 6-speed V6 4x4

and will I need anything else?

Tools. You will need a slide hammer to pull the axle out.
And either a press with a bearing separator or a cut off tool for the spacer.
Seems like the right parts. You have the M226 axle right. I guess that is a given since I don't think the nissan axles leak.

I think, my truck is an SV not a nismo/pro-4x but I think the 6-speed has the same axle, I'm not sure how to check though. I can get a slide hammer from auto-zone as suggested in the axle seal thread and have a grinding wheel.
