On my 08, manual trans the read diff was allowed to run low. A known issue when I bought this truck. The rear end does howl and the gears show signs of excessive wear and some heat. When I asked the dealer the cost to repair they quoted a whole rear axle. Gear set/gaskets/seals replacement wasn't an option according to the Service Rep. Does this about normal for dealer effort?

The truck has 259,000 miles and the rear axle assembly was replaced under warranty at around 30k. I am the second owner. According to the original owner was a custom ordered truck. He wanted a Nismo but in 2008 the Nismo wasn't available as a Crew Long Bed so he ordered an SE with a limited slip axle. So I was told. Does the VIN decode what axle this truck was built with? I don't plan to put as many miles on this truck and its normally a commuter. With this many miles is a new axle assembly a strong suggestion or overkill?

Thanks for the input and happy New Year!

Look at one of the bolts on the pumpkin, doesn't it have a tag on it? read the tag or better yet take a picture of it.
Most rear ends will state exactly what it is on that tag

I have never heard a special order limited slip rear diff/axle.

Are you asking for the gear ratios?
Model Axle Gears
XE KC 4x2 5M C200k 4.083
XE KC 4x2 5A C200k 3.692
SV/SE KC 4x2 6M M226 3.538
SV/SE KC 4x2 5A C200k 3.133
SV/SE KC 4x4 6M M226 3.538
SV/SE KC 4x4 5A C200k 3.133
SV/SE CC 4x2 6M M226 3.538
SV/SE CC 4x2 5A C200k 3.133
SV/SE CC 4x4 6M M226 3.692
SV/SE CC 4x4 5A C200k 3.357
NISMO KC 4x2 5A M226 3.133
PRO-4X/NISMO KC 4x4 6M M226 3.692
PRO-4X/NISMO KC 4x4 5A M226 3.357
NISMO CC 4x2 5A M226 3.131
PRO-4X/NISMO CC 4x4 5A M226 3.357
SL/LE KC 4x2 5A C200k 2.937

SL/LE CC 4x2 5A C200k 3.133
SL/LE CC 4x4 5A C200k 3.357

Edit:
I am guessing you have a C200k
Look for a used one on ebay , auto salvage yard, or an internet used parts website.

There are zero tags under any of the 12 bolts.

Yes I'm interested to know the gear ratios when the gears get replaced, same for same. I saw that gear chart earlier, before I posted.

If this helps to know, or show my ignorance, if I get mid corner wheel spin the SLIP light on the dash will illuminate/flash.

Minus the pumpkin tag, will the VIN verify the rear end build?

Manual trans gets the 226 rear only. I factory ordered mine in 2010.

I think a new axle is overkill. A new gearset, a rebuild kit, and a person with the know-how to install it should be all you need. If its not a 4x4 you could even switch to a lower ratio.

Dealer wants to sell axle to axle as it’s a maximum priced sale and completed in minimum time and no leaks no possible poor fitment of gears etc.

Exactly... That and they likely don't have anyone who is capable of doing a rebuild in the department... Check with your local independent shops for one that knows how...

I was visiting Florida and needed a u-joint and a carrier bearing and the tech struggled, imagine him trying to install a set of gears.

Heck if I've got a bench vise or big c-clamp and some sockets I'm all set with the u-joint...

They tried to get me to buy an entire driveshaft assembly.
I told him I have a 20 ton press at home and could do the job in less time than he whined about doing the job.
What shut them all up is I said “you know Roger Penske owns this dealership, he’d love to hear how you consider this job tough”. His race team could swap an engine in less time.

Is one of these axle groups (M226 or C200K) considered a Dana 44? A local gear and axle shop asked if I knew which one I might have. He claims one of the Nissan types is a Dana 44 and will be a different estimate of repair than the other type.

Thanks again

Yes, If I recall correctly, they say the M226 is a Dana 44.

It is built by Dana but it is a Dana 44 variation.
Ring and pinion gears are not interchangeable with other Dana 44, I believe.
Rugged Rocks sell a master rebuild kit for the m226.

I have a howling noise coming from the rear end when I take rounding turns or am driving between 10-45MPH. I can’t really hear it when I’m at highway speeds. So short of driving faster all the time I think I have an issue with my rear differential. It’s a 2008 Frontier Nismo 4wd. So assuming from the above how can tell which diff I need, if that Is my problem? PRO-4X/NISMO KC 4x4 6M M226 3.692 or PRO-4X/NISMO KC 4x4 5A M226 3.357? I’m assuming it’s one of these 2 based on the fact that it’s a NISMO and 4x4. It also has a 12 bolt diff. Appreciate the knowledge.
