17' Series Attn; 17.58-3ob owners

I use one only to reduce the porpoising out of the van. Im generally an anti WDH disciple for my own personal perspective. Nissan recommend against them, and from my layman's processing I just can't square away the extraordinary twisting force they apply to the tow bar and chassis. I have no interest in what the likes of Hayman Reece have to say about them, because they have a vested interest, but I would love to sit down with a Nissan engineer and have it explained to me.

Used them on the previous 16.49.3 and improved the towing (Especially by stopping the "porpoising" being single axle).
With the current 17.56.2 we can't fit them due to the off road hitch. Upgraded the suspension to HD and air bags, fitted an adjustable tow hitch and tows just like the old van with 26PSI in the bags!

I'm not a Nissan engineer and probably wouldn't admit to it if I was.
Think of the tow hitch as the the balance point of all of the downwards forces on the car/van combination.
When put the wdh on and pull the bars up onto the chains you are creating a rotating force.
This force is trying to rotate the tow bar down towards the ground through the car, hence the front of the car tries to move lower. The tow ball itself is trying to rotate away from the ground, hence the front of the van tries to lift.
The wdh at the chains is trying to pull the draw bar down to the ground.
This is why the forces are so large. The wdh bar, tow bar and draw bar are all carrying forces, mostly trying to balance the various loads between their contact points.
The wdh chains and draw bar. The tow bar connections to the car. The wdh and the tow bar.
When you go forward and turn you change left to right load distribution slightly. When you reverse you cause this change to increase to a larger degree (partially unloading one side and adding additional load to the other)potentially overloading either the car or draw bar. That's why you should always disconnect the wdh when reversing.
Hope this helps.

cut it out Landcruiser driver.............................
No I don't in the 17:58-3
The standard ball wieght is really low in these (130kg) even loaded up and modded like ours we are <200kg

I don't with my 17 on the landcruiser. Feels very comfortable without, and appears to be sitting flat.
However, I have a gvm upgrade which changed the factory springs. The handbook also suggested it wasn't required until the weight of the van exceeded the weight of the car.

I'm a newbie and have always used one. I think they're great invention.
Since owning my van i keep a look out at other vans on the road and notice quite a lot being used from the small to large vans.
