Oil looked perfect however Blackstone said after 20000 miles the wear was like 500000 miles.

2015 Frontier with 180000 miles

diff failure at only 180k especially with such constant service? it's gotta be defective. If the engine doesn't burn or at least enough to matter during an oci and the trans and everything else is fine I'd spend the money on fixing it.
Everything else is perfect. I think I found a differential with 20k miles for $900
Cheaper than a new $40k truck!

I have a 2008 Xterra (same drivetrain) with 387,000 miles. I also have a 2011 Frontier with 150,00 miles - also same drivetrain. I have had no issues with my diffs, but I have heard of pinion bearing failure on those on the Nissan boards. Is it the Dana or C200K - or if you don't know - what trim. Dana was used in the Pro4X as a locker, or in any manual trans version as open diff - everything else is C200K.
If its the more common C200K then the easiest solution is a low mile used one from a junkyard - easy enough to find. If it is not, then likely worth getting the Dana rebuilt by a reputable driveline shop.
Its definately worth fixing unless its rusty. They have a very reliable drivetrain overall thats simple to work on and parts are cheap. I am keeping mine forever.
Hopefully it is 20k miles. I'd also bump to a syn 140 since that does help to prolong the inevitable on some diffs with wear issues.
C200K
Have no choice but to fix it. I aint got $40k

With the excepting of the rear diff that looks like you have a replacement for, I say you are in good shape to push it to 300K miles easily with the kind of driving and maintenance regime you are doing.
You are kind of at the point were trade in value is not going to be detrimentally impacted whether you have 180K or 300K on it.

Thanks, I do take care of it
I did find one with 13000 miles for $800. I am going to try that.

Looks like the junky Nissan axle vent took it out
That VQ40 will go a long time. Great engine. Even Scotty, who hates Nissan (right or wrong, no fights please) reserves some praise for the Frontier.
What about water pump? Its internal.
I believe the plugged vent hose thing on these Nissans blows the axle seals out.
The other anomaly with the C200K is the wheel bearings are greased and don't rely on gear oil from the differential. I don't know a lot about rear axles, so maybe this is a common thing.
Those transmission coolers still failed under warranty with the OEM coolant. Different coolant chemistry was not at fault here.
That came from an engineers mouth from Nissan! You do realize coolant is changed at 30,000 miles and most dealerships don’t use genuine Nissan phosphate coolant, they use generic all vehicle coolant etc. only genuine coolant that was used was the Nissan blue phosphate enhanced coolant for 2009 vehicles and later.
Truly curious. How do you what what coolant they use?

How did the vent take it out? Did it blow out seals and the unit ran low?
No, it let moisture in and corroded the gears.
Replaced unit this weekend with a low mileage pull. All the gear facings where worn. Looked liked the corners of the gears where severally worn too. Very strange. Unit never abused.
