Had the dealer warranty the leaking pinion seal in January of 2011. Now, 6,000 miles later it is leaking again. I did the vent mod immediately after the first seal failed. So the mod didn't help in my case. I did probe it to make sure it was clear, and it was clear, so no new blockage. I don't suppose I have an recourse with the dealer, but oh well.
Anyone else experience a leaking axle after doing the mod?
Probably a bad seal install to start leaking again after 6000 miles. Just to clairify you did take the check valve style vent off the rear diff right and replace it with what ever method you chose? maybe the female threaded portion is clogged with crap from the original vent? Was the factory one clogged and jammed shut? And Ive had "the vent mod" done for years now and dont have an issue.
Yeah I replace the vent valve with what is described in the instructions and probed it with a wire and it's still clear. Probably due to the low mileage some rust formed and chewed up the seal when the driveshaft rotated.
more than anything the vent mod is to keep water out when driving through high water. a releaking seal would be more a sign that pinion bearing is to loose, driveshaft imbalance, poor install, wear groove on pinion yoke or a combo of any of these. The issue with the vent mod is IF the vent becomes clogged and pressure begins to force lube past the seals. That doesnt meen the seals wont be subject to to any of the other items that affect sealing
Ant then there are a few that have gotten new diff for sealing issues since Nissan doesnt rebulid diffs

Contacted them and they said it was done 2/10, so no luck with the 12/12 repair warranty. Cost they quoted was $345...not happening with them but I'll do it in the spring.
Yup, did the axle vent mod and still get leaking seals every 30-40k miles. It's because the axle shafts are corroded/worn and grind the seal surface back down. The only way to really fix it right is to get a whole new axle shaft. Ask me how I know....
BTW, I've been through 2 driver axle seals, 1 passenger axle seal, and 1 pinion seal.
