Bad design or bad seals. Nissan still doesn't know how to fix this. Just keep replacing the seals.
One failure doesn't mean the axle vent mod doesn't help. Maybe your seals had damage before the vent mod. We appreciate the report.x2thez said:OK, before everyone gets all pissed at me for posting this, let me preface this with I know what I am doing so dont sit here try to insult me be saying that I could have installed a hose wrong.
I purchased the Toyota part to install into the vent on the rear axle, I then installed about 6 feet of tube and on the end of it is a fuel filter. I have been running this setup for about 10k. The other day when doing an oil change, I noticed my passenger side rear seal is leaking. I have had the truck since 36k, and it now has 65k, that side has never been replaced, but at about 40, the other side was. Anyone have any GOOD ideas as to why this happened? Oh by the way, the first thing I checked was the rear diff fluid level, and all is good. I am running 75-140 severe gear amsoil in it.
That is really sad a$$....In 2008 with a new design, AND there are still leaking issues?In model year 2008+, the axle shaft assembly design has changed with a larger shaft, larger wheel bearing, different wheel seal and added dust deflector. However, we are having some leaks reported with the 2008+ design as well, we are working on solving this issue as soon as possible. Nissan is pushing Dana Corporation very hard to resolve this wheel seal leak issue.
