I just cant get with this program...

It's all speculation...until they release more details

Yes, a 13" ring gear is humongo and kinda sorta knew it is in the translation
from metric to English.

There are also 14 bolts to the GM HD 11.5" ring gear and it 'was' referred to as
a 14 bolt...until the confusion of 'which' 14 bolt...just a different 14 bolt PATTERN

Speculation...like the all aluminum Ford pickup...does anyone know if they did
the same as Audi's all alu cars?

Over lap spot weld isn't strong enough in some areas and Audi has cast/forged
(don't know which/where) as interface and then seam welds the alu formed sheetmetal
to those interface castings/forgings

Or has Ford gone to seam welded alu sheetmetal joints? That is expensive, takes
more time and the biggie...high potential of warp-age

Again all speculation until it shows up and logs lots of miles.

Like the sledge hammer to Ford Alu bed...who knew that they embedded the side
view cameras in the tail lights? Dumb to me...as each corner is a highly likely
to be dinged area...then with the expense...wait till the thieves figure out that
they are of high value

Not to say anyone is all bad or any one is all great...they are *ALL* becoming
so 'highly integrated' that the cost is going to be exrtemely HIGH...

The only reason that market is "sewed up" is because they have no competition....I'll bet if Toyota brought out a truck with the same #'s as a 3500 from the big 3, they would sell like hotcakes....

Those of you who brought up overkill in a 1/2 ton make a good point. I also agree that the bigger baby Cummins would hurt the payload of a truck that can't really afford that loss. I would say that these 400 hp motors pushing 900 ftlbs of twist is overkill in my book and I would love to see a motor like this as a HD option, close to perfect for my needs.

Not sure why the "half ton" badge persists here...no specs have been announced. If Nissan rolls this out with a 9000 GVWR, will you still call it a half-ton because it only has 6 lugs?

You guys need to look at the numbers before making any sweeping assumptions about about what this truck is or isn't.

Exactly.

This Nissan will have a 13" ring gear from AAM, an American firm, with larger
axle tubes but only 6 six lugs from the pic's. What is missing is the lug bolt
size. I've seen 5 lug nuts on large trucks, but those lug nuts are in the 25MM

There are two "14 bolts" that GM has used over the years, but only one is currently used in the HD line of pickups. It is only found in 2500's with the 6.0. This axle is called a "Corporate" 14 bolt full-float, made by AAM.

The duramax and 3500 axle is not called a 14 bolt, it's the AAM 11.5" axle and goes by that name.

The other 14 bolt is the axle pictured on the Nissan website and is a 9.5" ring gear AAM semi-float axle, sometimes called the "Saginaw" 9.5".

There is also an AAM 10.5" full-float axle, but it is different that the "Corporate" 10.5" full float axle that has been used since the 70's by GM. The Ram 2500 with a Hemi is the main user of the AAM 10.5" axle.

The 14 bolt semi-float "Saginaw" has had RAWR of up to 6K lbs.
The 14 bolt full-float "Corporate" has been SRW and DRW with RAWR of up to 8,600lbs.
The AAM 10.5" full-float axle has a RAWR of up to 6,000. The axle itself has a higher rating around 9K lbs.
The AAM 11.5" full-float is used SRW/DRW and OEM axle ratings up to 9,350 lbs. The axle itself is rated for 10,912 lbs.

There isn't a single class III pickup using an axle with a 13" ring gear, the largest is the Ram 3500 with an 11.8" ring gear (HD variant of the AAM 11.5).

While there is a source, pickuptrucks.com, that states 13" ring gear it's not logical to be anything but a typo. Why would a truck with a 10k lb tow rating, and 555 ft/lbs need a 13" ring gear??? It's being advertised as more than a LD, but not quite a HD... not 13" ring gear territory.

It's wiki... but they have some info on all of the axles listed.

http://en.wikipedia.org/wiki/10.5%22_Corporate_14_Bolt_Differential#11.5_AAM

There are very few specs on the XD out there, but the tire size and rear axle ground clearance numbers that Nissan provided indicate the ring gear is smaller than 13".

Not a source I will hold my breath for... especially since the transmission in the photo is not a AS69RC.

Aisin makes more than one transmission.

I was thinking the same thing, since Aisin makes a huge variety of transmissions. Virtually every Toyota with an automatic has one including the Tundra. I would think it more likely that Nissan would use a version of that transmission rather than the Ram version which is similar to that used in medium duty Japanese trucks.

Should be OK if they put a good trans and rear end behind it.

They are apparently using the same Aisin 6 speed auto that is used in the RAM 2500 and up series trucks. I don't have any info about the rear end.

Which Ram 2500 uses a Aisin??

Sorry, 3500 and up.

Yup looks like it might have that $1200.00 drive shaft/u joint set up that jeep had.Maybe still has.I had one.Who hoo.

In concept not too bad. It will likely have its place among the 1500/150 crowd but until I see it with HD front and rear axles with 8-bolt hubs I think it will only sell to those who want/need the lowered payload but want power to tow with that decent sized diesel for a 1500/150 series truck.

This decision seems to be made based on marketing more than practicality. I maybe can see them wanting to put a Cummins in the Titan, but the same Aisin the HD Rams use? Come on now. That is overkill and will result in less MPG than if they used a more reasonable transmission for a 1/2 ton. This truck is too much like a half ton to be used as a heavy duty and probably will be priced like a 3/4 ton from the big three ie people will buy the HD from the big 3. If they think that this thing is going to find its way into construction sites and oil fields they will be sadly mistaken. I have never seen a titan or tundra being used on a job site unless they are a painter or something. And for us RV people, we are going to still use HDs from the big three. Ram had the right Idea to put a reasonable engine in a half ton platform for good MPG. They knew if people needed more capability they would go to a HD.

Maybe I'm just a pessimist.

I agree 100% and that's why Toyota will never make a 3/4 Ton truck. How many would they sell? The Big 3 has that market sewed up.
