Hi James,
Reading Ruby's post link below, NTB had a similar vibration under hard acceleration with no trailer. Turned out to be the front drive assembly.
Do you get the vibration under similar conditions - no trailer, hard acceleration?
Also notice both you and Ruby are in SA and deal with Solataire :o ......
What do you mean by front drive assembly?Quote:

From NTB's post on the link below, "... found it was a issue with the Front Drive Shaft. The Front Drive Shaft did not appear to be faulty in anyway from the inspection. I replacement Front Drive Shaft was ordered anyway and fitted. The Front Drive Shaft assembly included the universals as well."
Hello All,
Since my front drive shaft assemble has been replaced (at about 1 or 2 months after delivery) I have not had any further issues.
I was fortunate when the Service Dealer could not work out what was actually wrong that they then used a Demo Vehicle to swap out parts. Once established what had to be replaced, new replacement parts were ordered and fitted to my vehicle. The Demo Vehicle was installed with it original parts again.
I hope you get to the bottom of your issue James.

Thanks Neil for the input, I will keep everyone posted.
Testing my boat with the MY13 D4 this week and towing a mates boat also try try and confirm a few things.

I too have a similar issue, however not as severe. Mine is only noticeable on smooth bitumen roads when towing above about 80 - 85kph. My symptoms are a light 'shudder' for about 1 second, about half second of smooth, and then 1 second of light shudder and so on. Coming back from previous trip, did seem to be getting worse, however may have been my anxiety/imagination.
Car in for service next week, and is on issues to review.
This sounds like the trailer stability program doing its work. I reckon you found the sweet spot of a harmonic on the trailer, and the car is doing what it is supposed to, and correcting the sway, before you notice it.Quote:

I bow to your greater knowledge on this issue, but I would not have thought the van (2t off road camper trailer) would be out of shape at such low speeds. Will be interested to hear LRs explanation.

Basil, do you think you'd notice or hear the light application of brakes similar to the "fluttering" of HDC when the trailer stability system is active? I assume that it uses the brakes.Quote:

You MAY have found a harmonic sweet spot on the camper, which kicks in at those speeds. See what LR have to say.Quote:

On a normal Aussie road ;) I have never felt it working, but do on those rare, smooth sections. I don't tow a van, but I would suspect that the trailer assist would be working harder if the van was hit with a cross wind, or similar, causing it to start to get out of shape.
