WOW.. how bent is the chassis... and it doesnt even look like a large hit on the door!

That's why when I cut down my 80 series the chassis was made to never break and was done by a marine boilermaker.

You get a little flex but she sits solid on and off road.

The doubler plate finished forward of the rear wheel on the chassis and is 5mm plate.

You'd be doing well to bend an 80 series chassis!

A neighbour showed up with a bent d40 navara today. Heard something about a washout. He was towing a trailer but not heavily loaded.

That's because all the dual cabs today are just glorified models of a decade ago when they were rated to handle 1,800kg with upgraded brakes, motors and sales brochures

It does say "Flexiglass".

And I would have sworn it was aluminium . You just can't trust those new fangled composites .

BINGO...........

Dave,
Chassis in the early '90s were a poo poo load stronger, thicker, designed, fabricated etc than today's crop of wafer thin steel pretending to be a chassis........add in the fulcrum effect and you get...........snap........

I have just reread this whole thread from wo to go, the above statement made way back in October 16, 2013, nearly hit the nail on its head.

Yes I agree that air bags can and do have some affect of chassis bending/breaking and yes I agree with Metters and his statement from  October 21, 2013.

But the earlier 4x4's including the 60 series and the Nissan GQ range had chassis made from mild steel and were thickr than modern chassis.

The newer late 90,s onward 4x4's went to lighter, thinner HIGH TENSILE steel to build their chassis with.

High tensile chassis are in fact stronger than their heaver MILD steel cousins, but unlike mild steel ( if not made thick/strong enough they will bend, but seldom break ) , HIGH TENSILE steel fatigues with constant flexing ( same as Stainless Steel ) and in time the high tensile steel will develop cracks , the cracks weaken the chassis design and will fail.

In the mining industry, particularly the underground industry , the average age of a vehicle ( mainly Toyota Landcruisers are used in this industry ) , is only a couple of years before the chassis fail and the vehicle becomes land fill.  No air bags , not that much in the way of overload, but constant flexing of the chassis.

Mentioning the mining industry.. Years ago back around 2000 - 2001 I was bringing Land Cruisers in from Freeport Mine in Irian Jaya.. Used to build utes using the 1PZ turbo engines.. (That's another story) Bottom line is the mid wheel base cruisers from Freeport were stripped down to the bare chassis, Australian long wheel base chassis's were used to build the utes. A bare Australian ute chassis could be picked up by two people, one at each end.. But the bare mid wheel base chassis of 1990 vintage needed four people to pick it up..

   Very true. People forget the intended purpose of design. In the case of dual cab utes it is to essentially carry five people and their tools/equipment to a work site. Personally I think it is nearly criminal for these manufacturers to rate these vehicles with 3500kg towing capacities. People load them to the limit or beyond, throw a 2 tonne van on the back and then hit dips and cattle grids at 100kmh and wonder why something fails.

That should  " Buff Out  "

Here is another one. Must have over loaded the tray.

Similar sort of scenario killed a bloke at my old mans work years ago.

The mounting bolts look as though they didn't go very far into the slab

I was talking to a hoist installer when we had one fitted to our workshop. He said a few times he's go to a job and drill through the '250mm slab', only to find it wasn't even 100mm thick.

One place had a hoist there for years, bolted through 80mm of concrete. more good luck than good management.

I knew a bloke in Newcastle that punched a hole in his slab in the garage changing a tyre. The vehicle went up on the jack and then the concrete started cracking and the jack went through the floor. The builder skimped a bit on the concrete by all accounts.

l drove my 650kg tractor over a 100mm footpath , it cracked . l was going to have to pay the damage till l asked to sample the path for depth . the concrete was 12mm thick at that spot & no reo at all . the tune was very different after that  .

I googled this topic last week and found a bucket loead of bent dual cabs regardless of make....people just don't understand axel loading ??

I got married in Nagambie a few years ago!

Has anybody seen a bent Isuzu Dmax chassis?  Was discussing with a few mates the other day and a google search failed to find an example.

12mm is rude. Most councils have gone away from putting reo in footpaths these days - not required.

The bent dual cab ute thing has been happening for a long time, in 1990 when I was last on the spanners for a job as a mechanic, a lad i worked with bent his dual cab with the weight of his tool chest sitting in the tray against the rear tali gate. That is the standard style side tray, no canopy.
All that took was speed humps in car parks. It never went off road.
We sorted it out by adding a spacer under the rear tray mount so he could sell it.
You do know to never buy a car from a Mechanic don't you 
Just today I noticed one in a car park, a late 90's model, just a very slight bend to it, the gap between the tray and cabin gets wider the further up you look.

Well yes I do but I am not asking for any bragging rights, just that I am genuinely interested if there are any reported cases.
