Having just bought a D22 Navara and am a little dubious about the capacity of the rear leaf springs I have been trying to calculate its load carrying capacity.
I have a handle on GVM, GCM etc but my registration papers have a Aggr: figure.
This is obviously the Aggregate for the vehicle and I am guessing this is the same as the GVM but I am unsure as the numbers dont add up. i.e.:-
Rego Papers
Tare : 1880
Aggr : 2765
GCM : 5765
Navara Brochure Specifications
Tare : 1695
GVM : 2920
Carrying Capacity : 1225
Does anyone have an OFFICIAL definition as I may try to get Nissan to beef up
the springs under warranty ( I have searched previous posts to no avail) .
Thanks
Steve

Do a Yahoo / Google /whatever search under "Vehicle Aggregate Mass"
It'll keep you busy reading for the rest of the night.

Try to carry 1 tonne ( like it says it can ) and see what happens..
To comfortably carry more than 600 Kg's you will need Poly Air Bags,, and that figure is more like 500 Kg's

I agree, handling was becoming dangerous at 600Kg+. I intend to take this issue further.

Hi Steve M,
Beware of the navara lean. A lot of navaras drop
[
suspension} on the drivers side buy about 15mm unloaded and 20-25mm loaded. This lean is within nissans tolerance and won't be fixed under warranty so don't waste your time asking. I find that 500kg in the back and the vehicle drives a lot better, to much more and the handleing slowly goes out the door. My rego and nissan hand book shows only 1025kg carrying capacity, what the differance is between yours and
mine ???? Mines a D22 series 2 V6 Petrol.
Regards,
Camwill

Mines a D22 single cab 3.0 td
I am about to post a question about other year's GVM for this model so have a look at that.
Warranty may still be an issue, will keep
forum members posted.

You are guessing correctly, GVM (Gross Vehicle Mass) and Aggregate ARE both the same thing just different terminology. They are both the product of Tare (weight of empty vehicle) + Load = GVM or Aggregate which is the maximum weight the manufacturer has designed the vehicle to be from an engineering perspective when fully loaded. Therefore the heavier your vehicle is empty (including accessories such as bullbar, winch, etc,etc) the less load you can carry in terms of stuff you can add or subtract from the vehicle when going away. The GVM stated by Nissan in your brochure "should" be the correct figure and if the brochure is incorrect as stated you would have an issue with them if the brochure is for the same model year and variant as yours, even allowing for the "catch all" rider on the bottom of all such publications about "we reserve the right to product improvement at all times and as such specifications may vary so check with your dealer". It is highly possible that GVM on your rego papers is the wrong one due to human error either on the part of the dealer or your State licensing authority partly due to slackness as
well as the fact there are literally hundreds of model variants when you consider different years, engine & transmission options, fuel options, single cab v double cab as
well as body options such as ute, table top, bare cab chassis, etc. If it is simply a case of the wrong figure on your rego papers your licensing authority should correct it for you at no cost. I agree with the other post though that said "just because it is rated to carry a tonne or whatever it doesn't mean it will handle real
well at it's maximum rated GVM".

Didn't realise the GVM is stated on the compliance plate ie 2765Kg. This doesn't explain why the brochure states 2920Kg for the exact vehicle ie 4x4 STR single cab chassis 3.0 td.
