That pfffft sound we heard when you removed the factory breather tells me it wasn't working properly. There was pressure in the diff which could have blown your axle seals. Not good!

Best diff mod video I've seen yet. About to do mine and this is very helpful. Thank you!

I think if you checked this every year or so clean it with some carb spray or something you would not have a problem I owned a eighteen wheeler that kept plowing seals saw this little breather on the axle one day while pressure washing my frame cleaned it and never had another seal blow. No I don't mud bog with my Frontier, this is probably a good idea if you do.

I concur, best video Ive seen on this mod , well done and useful info, thanks.

Filter is made for 5/16 inch and 3/8 inch fuel line. You're using 1/4" fuel line.

I installed the same kit,very easy to do. Great Video!

I just bought a 2019 SV. Thanks for the how to video. I will be doing this on mine soon.

Lose the filter it will attract some moisture in time and also limit air flow , which defeats the purpose. You’ll be changing those out once a year or should. The breather vent doesn’t have a filter, it won’t get dirty inside the tail light housing anyway.

Probably just use a $5 fuel filter for a lawn mower.

Hey TO, thanks for the info. I’ve a ‘14 Frontier with about 100,000 miles. So I’m gonna try this and hopefully before I blow a seal.

Could you please list out the parts you used, and where you got them? Thanks!!! Appreciate the vid.!!!

Excellent work thanks for sharing!

Great vid I don't think that hose barb 9040-51026 works on the Pro 4x. Tried it and threads didn't line up probs cause of the larger axle.

Wish i would have seen this earlier. Both axle seals are leaking on my 21’ with 26k miles

Hi, good work. Can you tell me why you used a fuel filter for this mod? Thank you

I have a 22 frontier with 15k. My pinion seal is leaking really bad .I've always had some whine on acceleration uphill so I'm assuming they are related .after the repair (hopefully replacement) I plan to do this mod .I've never went off road with mine yet

Is this for the M226 or the C200?

I wish you show which way the filter goes I just installed mine but didn't know how the filter go like if it has an up or down way to put it in place.

Nice install vid!

Any idea what the part number is for the Toyota part you installed?

What’s that bar going across the bed of your truck for?

Is this necessary if you don't off road?

Where can I find the parts for this?

Offtopic but what size does a Nissan Frontier 2019 axle carry d40 or d44?

Toyota part is the wrong tread. Ordered it and I’m not about to cross thread the shit out of it
