Jayco Outback - Axle

[Teabag]

Just out of curiosity, who's Axle is sprung over or under your leaf suspension? Also, is yours the upgrade 2ton suspension?

Now, the reason I ask is my Jayco Hawk outback and Nutto has exactly the same camper with only 10 or so difference in build number yet his is sprung over and mine under. This gives him an easy extra 3in in height. The only diff is mine is the 2ton suspension and was wondering if this is the norm or and Jayco, what ever works on the day type thing......

[Black Diamond]

A little confused now going outside and getting my head under the Jayco
Jayco specifically state that the Outbacks have the "Underslung axle" for improved Ground clearance, which is standard on the Outbacks as per the following pic.


Mine is spring is under the axle. Think i better give Jayco a ring on monday 
This could get quiet messy as the annexe walls will then be too short if its fixed.
And as far as i know Jayco automatically upgrade the GVM when two water tanks are fitted, and having a look at the placard mine is not. Maybe they have placarded it wrong as Teabag you are saying you have the 2t upgrade and the axle is also over the spring.
Anyone know what the diiference is in the upgrade?
Teabag is there any chance you can count how many spring leafs you have, and possibly someone with the standard GVM?
In that case by the time the water tanks are filled i am stuffed!

Sorry for all the questions, i think you may have opened a can of worms.

My placard in the front boot states 2000kg and mine is 7 leaf springs but not sprung over as in your picture. I may have to call Jayco to see if this is what they do for the 2t suspension. Nutto's was an easy 3in higher.....

When I ordered my Jayco I specifically asked for the 2 tonne axel upgrade, my dealer told me because that I'm  going twin water tanks and a few other options that my hawk would be to heavy and that Jayco would upgrade the axel at no charge. If I specifically ordered it with axel upgrade it would cost me $400.00.
Seems to be a bit of a grey area.

Yes, not really the query. I'm just trying to work out why some appear sprung and some are sprung over.......

I have a 2010 Swan, but asked specifically for the axle to be underslung and u/g to 15" tyres for extra ground clearance, but this is not indicated on the placard for some reason? I also have 2 x tanks but don't recall anything regarding axle upgrades?
ATM: 1414kg
GTM: 1288kg
TARE: 1114kg
Axle load capacity: 1400kg
I have 6 x leafs fwiw

* Forgot to say that I have shocks fitted as well, not sure if this matters or not?!?!

This will be an interesting thread to watch, wonder what sort of warranty work Jayco is going to be up for.

[Teabag]

Well, interesting results already. Might have to give Jayco a call with WTF......I want sprung over to gain the height........

[Black Diamond]

Turns out i have got the 2000kg axles, i just was not looking hard enough! And it has 8 Leafs.
I still might hit them up for a Payload upgrade.


Back on topic, look forward to Jayco's Response on this.

Interesting, yours and mine have same payload but one is slung different to the other. When it goes in for warranty on the door, they can spring it over.

Mine was built 8/09 it is set up as per the picture Black Diamond Posted.  My OB was standard and has an axle load capacity of 1600kg according to the compliance plate.  Interestingly is it has a empty ball mass of 137kg and BD's has 133kg.

[DANBRI]

Mine was underslung from factory.

[ehsc]

My 2005 dove outback is under slung standard from factory with a load rating of 1350 kg.

As per Black Diamonds posting "Outback" should have "Underslung" axles  imagine my surprise when our Outback Expanda arrived without   I enquired about this with the dealer, who said it was something to do with legal coupling height requirments   go figure they run the same chassis as the campers just wider or longer as the case maybe.

At a show I looked under another the same model as ours, surprise surprise "NOT" underslung, then looked at a Sterling Outback dual axle. and it was underslug  

My 06 Eagle was underslug
08 Swan was Simpicity
10 Expanda overslung

[Old Croc + plus one]

G/day Teabag

Our 09 Swan O/B is over sprung 7 leafs and 2 rebound springs

Atm 1572      Gtm 1427    Tare Mass 1272

and the Empty Ball mass is different to yours and Black Diamonds our Mass Ball Weight 145  ?? don't know why they are different

Load Cap 1600

Thanks again for your valued input.......

No problem, I checked my Goldstream but it doesn't have an axle so that's all I had to add

So, that makes you a post whore then.


Wouldn't expect anything less from a Goldstream owner.........

[zed]

Wouldn't the ball weight vary on models and accessory's, (1 or 2 gas bottles, pole carrier, 1 or 2 water tanks, battery's)
My 07 eagle O/B was under slung 

[AKB]

Our 08 hawk o/b is underslung

[V8ute]

   My 10 eagle is underslung.
That lift will alter a few things?? Annex walls, hitch height, stonegaurd.
   V8ute.

I second that  post whore he is 
At least we get ours out you load and proud keyboard Camper!

You Jayco owners must be weird. What is an axel? Is that anything like an axle? 

[Nutto]

So, it seems that:
Outback with 1.5t axle has 7 leaf pack with axle underslung, which is what mine is.
Outback with 2.0t axle has 8 leaf pack with axle overslung, as per Teabags, BlackDiamond, which also results in 2-3 inches less height (which annoys Tbag no end ).

This is all related to legal hitch height, which Jayco are quite anal about.  I found this out way back when I was researching campers, and asked Jayco t'ville about underslinging a std on-road jayco, to which they said they would not do it as it would put the drawbar hitch height beyond the legal limit.

Now, the hitch height on my O/B is near on the upper legal limit of about 420mm above ground.
With a 2.0t axle (assume it is physically larger than a 1.5t) and the extra leaf (all of 6 odd mm), these must combine to put the drawbar over the legal height if it is underslung like mine,   and I reckon this is the line that Jayco will push when you ask them about it.

One thing to remember about this whole hitch height thing is that it only talks about "towball" height.   Nowhere in any of the literature does it mention or relate to couplings (Tregg, orac etc), so, Teabag, I reckon dig up some info on the legal ball heights and, if they take this line, hit them with the "but I don't have a towball, I have a coupling - the laws only talk about towballs" approach.

Until then, looks like you have 3 inches less than me!!!!    There's a reason why I walk they way I do LOL
