Thread: The Discovery 4 is a second rate tow vehicle

The LC 200 owners are in a no win situation that many ignor. Toyota say a WDH is required but only a Toyota approved WDH should be used. There are none approved by Toyota.

The problem is just what Brad has said,WDH are a bandaid solution.I used to regulary two 2 tonnes with my defender but I fitted HD rear springs and it never changed the way it drove.My vehicle dropped an inch or so but thats it,no wandering or nervous steering,if you think about how WDH work you can also see how fitting taller stiffer springs with dampers to match would do a better job,fitting a WDH to a vehicle with it's bum on the ground is plain stupid,just fit the correct suspension.

If the nose weight cannot be reduced or reduced safely then you are stuck with it. It does not matter whether you can get your vehicle to stock height using stiff springs or air bags - the weight levers the back of the vehicle causing weight to come off the front. You cannot lever that back up without WDH's as I see it. I know guys who tow heavy all the time and even with rear suspension that is HD and does not drop when the van is on, they use WDH to restore weight to the front. I am not asking about weak or poorly maintained suspension.

From where I sit the wieght changes as the suspension compresses and then rebounds so the rig pogo's at it's center and the WDH tries to control that,which is the spring and dampers job. Pat

When I told our caravan serviceman I was going from a 79 Series Cruiser Ute to a D4 he was worried about the WDH issue. He phoned his mate who is the manager of a Hayman Reece store, mate said that they have looked at manufacturing something for the D4 but when they got hold of one they realised that they could do nothing to improve it, in his words "It is simply the best system on the market".

Seriously guys, we have argued this ad-nauseum on this forum. Please search first - we've covered EAS versus WDH, natural vibration characteristics of WDH, why they're seen as a "perfect" solution, why they're not etc etc etc

And you don't need to ponder the semantics of "should not" versus "must not". Land Rover Australia will not honour a warranty claim on your EAS system if you use a WDH system. That should be all you need to consider.

All well and good but if the issue goes on to court the wording will be carefully considered.
