    Ruby2, Dave is getting quite technical. TC is torque converter.

    You need to watch the tachometer to see this happen.

    Our horse float, as I mentioned earlier, is 3.5 tonne. For me driving with heavy weight sport mode is the way to go. But the D4 revs pretty hard with my weight, so I keep it in normal drive. It still revs adequately high enough for me, but not near the 4k mark it will go in sport mode with this weight.

    In my Toaureg towing the same trailer, sport mode is better, as the engine does not rev as hard as the D4, but in normal is too relaxed for my liking.

    On inclines I do flick across to manual mode....just wished LR put it on the right and not on the left....a real design flaw IMO.

    Brett.....

    Ok thanks for that Brett.

    Yes I agree it would be far more intuitive if it was on the right (sport mode) that is. I find I do go right and then doh!! its to the left!!

    Chuck, yes bearings all good and checked...all have good grease....I married my mechanic so he's got a vested interest

    Called the float manufacturer today and asked some questions he said "Oh I think a wheel alignment will fix that" to which I replied I am way ahead of you....done wheel alignment on the car and the float, check the bearings etc etc.......did some experiments......all my responses left him very perplexed.....if the car does not suffer this with the Olympic brand float then one thinks that it's the float design or suspension?? which is causing the issue!

    Nah I wasn't saying that, I hope it didn't come across like that appologies if it did was just giving a comparison on similar problem and was moreso trying to get across needs to be level hence my lifting my van a bit to achieve this.

    Ha ha my husband sits on the left but there is no way I would give him control of my gearbox He's only allowed to drive Ruby when it's absolutely necessary I never did share my toys well when I was a kid!

    Interestingly to add to my experiment and because my brain has not stopped thinking about this.....tonight we hooked the float up to Hubbies paddock basher Prado added 500kg water tank and off we tootled. Just to make doubly sure. The float did the same thing with his car also.

    So far we have done:
    Float and Disco - wobble and sway
    Wheel balance on float and car
    Turned tongue to be in the high set position
    Float and Prado - wobble and sway
    Disco and another float - no wobble or sway
    Tonight the float will get a wheel alignment check so we can say what's going on but I can see (I reckon) that the front drivers wheel on the float is toed out and quick check confirmed this.

    I think I should have been a scientist really! However, at least when I make a call tomorrow I can say I have saved them a lot of time in trying to work out the offending culprit of this issue and it's not the Disco or the hitch.....

    Thanks again everyone for your advice, tips and thoughts they have been great and I appreciate the time you have taken to type them!

    Still no wiser

    Since my last post we have done the following:

    Jacked up float, spun all wheels to make sure hubs have not been drilled out of round.
    Placed a 60 litre water tank in the tack box at the front of the float as close as we can get to the draw bar.

    The hubs are acceptable.
    The water tank has made a slight difference but it's still skipping around and wobbling just a bit less than before.

    Off to the place I bought it from on Tuesday night to take the owner for a drive in my car with float and water tank! He took the float, unloaded, and it didn't put a foot wrong on his car....I should have taken it to him with the tank.....

    Sigh........
