Up around Coen the other week saw a new Navara dual cab with a bent chassis (opposite the hotel), locals said it's the 4th one so far.

Has anyone heard of this happening. Bends between the cab and the
styleside.

Yep,
saw one on an email a while back, also happened on the cape.

This on buckled upwards, the chassis bent not far forward of the rear axle.

Story was it hit some large bumps on a formed road, don't know if this was the case or not.

Are these the D40 or the D22?

D40
The guys I were talking to said that it wasn't towing, or overloaded in the rear.

Haven't heard of it with a Navara, but seen it on Hilux and Rodeo dual cabs.

It happens to dual cab models because they have no weight forward of the rear axle and often a heap of weight behind the rear axle. Drive them over the rough stuff and the chassis bends, opening up the gap between cab and tray/tub.

If you've got a dual cab, its best to keep the weight well forward.

Thanks Phil G
Makes sense, good to know it's not just a Nissan thing, but a dualcab problem.
Main reason I raised the question, a mates son just bought one. Will give him your advice on loading, when touring/trekking.

rockpiglet,
I used to own a dual cab courier which had a theoretical payload of well over 1 ton, I say theoretical because the gross vehicle mass, less what it actually weight, left payload of approx 1.3 ton, ALL of which sat behind the rear axle.
I once went to put 950kgs of pavers on, and could see a bigger gap in between the rear of the cab, to the front of the ute tub.
I did two trips that day and wondered how in the hell would you get 1.3 ton in there with out it snapping, Alright for a standard ute, At least you have the ability to get some weight forward.
I don't think that this is confined to Navaras, vehicles don't have to be overloaded to buckle up there.

It really surprises me, if it was a commercial heavy vehicle and the chassis was bending while loading within GVM, it wouldn't happen for long.
Law suits and loss of sales would follow.

I understand the road conditions above Lakeland, but you still wouldn't be happy.
I wonder if the manufacturers have safe loading advice in the manuals for the novice.(going to read my mates)

Also with the cost of these vehicles why aren't chassis reinforced, or bigger rails, or even dual chassis rails in the stressed areas.

Seems to be so many dual cabs on the road, must mainly be people movers, with only light luggage!
As it sounds like you wouldn't want a large weight downloading the tow bar either.

The problem is weight distibution, you just can't get it right with a dualcab, All weight sits behind the rear axle and actually takes weight off the front, no good for anything,and I have had a heavy trailer on mine and you can see it flexing in the mirror when it was driven on tar, and yes I beleive you are right in saying that they are people movers with light loads, in the last few years dualcab sales have sky rocketed as well as the trim levels, just look around and see how many there are around.

based on my observations I am not surprised the Navara bent....seen a couple of them like it.

Nothing to do with the Daul Cab...I have had 6 Dual Cab Hilux's and they have travelled on the roughest you can through at over the years..and fully loaded at that..never hurt them at all

The Navara's I know of were travelling with me and they bent....

Had my D22 loaded up very heave quiet a few times, but keep as much weight forward, and have the lighter stuff at the back.

Sounds like a weight distributation problem to me ,,
Rodeo's are renouned for it, but a Nissan ???
Bloody hell what is the world coming to ??

Not everyone is telling "porkies", just some

I am interested !

Pls keep me posted
Cheers Bucky

The locals I spoke to up at Coen said it was new models only, 4 so far. I didn't get too in depth as mainly spoke about fishing!

I wonder if there has been a chassis re-design for the latest model?

I like to think that you need large incorrect weight distribution/ overloading for this sort of thing to happen. But then you would think the light steering, and front end handling would let you know somethings not quite right?

Has been happening for a long time with holden. Not sure but would imagine alot of people would remember the old holden one tonners, HQ'S, J's, X's, Z's majority bent in the middle forcing the backstop at the top on the tray to lean against the rear of the top of the cab. Sounds like nothing changed. Regards Steve M

True, they were usually over loaded though.
Seems to be 2 changes 20 years later.
The chassis bends the opposite way, and you don't have to be heavily loaded for the privilege.
