    Well, since everything has been "done" its time to take it back to those who "did it" because it hasn't been done right.

    Hi Patrick

    You say that the springs fitted to the car are taller and designed for a heavier load. If you are using Koniís standard replacement (heavy duty) shocks for your vehicle then I have a couple of questions.
    Did you have them revalved to suit the heavier springs?
    have they been matched to the spring length?

    If you have only have their replacement shocks, they are only designed and valued to suit standard (original) springs in the car.

    You MAY be able to get around your issue by adjusting them (and do this only if you know how as it is all too easy to unscrew the foot valve with the result that they will need to be rebuilt at your expense). Sorry, I hope Iím not telling you stuff you already know...

    The adjustment on Koni shocks only affects the rebound damping and not the compression damping. Given that you have heavier springs I donít see this as a major issue, as you are wanting to better control the rebound of the springs, from what you have described in your original post.

    There are about 5 - 5/2 half turns of adjustment and in your case I would probably adjust them to about half way (about 2-3 half turns) and see what difference that makes. If the symptoms donít improve once youíve done this then I would look at revalving them rather than adjusting the rebound even harder. Adjusting them harder could result in binding up your suspension travel and make the ride and handling even worse.

    Having them matched to the length of your springs is less of an issue given your symptoms but you do need to be sure that they donít bottom out or top out before your suspension hits the bump stops or reaches full droop otherwise you run the risk of destroying them. Some manufacturers design their vehiclesí suspension so that the shocks perform the task of limiting suspension travel but itís a less than ideal design in my opinion.

    Cheers

    David

    If its the death wobbles.... I fitted a new rubber bush kit..... and didn't even get 1000km.... out of the panhard bush before it was aboslutely destroyed. The car was near undrivable above 80km/h....

    The cheap rubber bush kits are ****house. Avoid at all costs.

    Check the pitman arm nut and I would recheck the hub bearing and swivel pre loads.

    Absolutely, they're the main simple things that would cause this if everything is 'new'. The pitman arm nut can seem tight but there can be a lot of play.

    FIXED IT

    Hi Again Blokes
    Thanks to all of you who offered to help me find a cure to my problem, I very much appreciated it, a lot of the suggestions to fixing the problem were not the answer but the fact that they were mentioned made me re-think and also re-check everything that I had done to the old girl however when Phil B mentioned the "Death Wobbles" and posted a link to look at I did so and thought about it all once again and realized that the only thing I had not done was replace the steering damper, so off it came, testing of it proved it was stuffed and justifiably so as it was probably the original unit making it thirty two years old.
    I tried to locate a new Bilstien unit to replace it with (I have used them before with good results) but I was not happy paying $260 including freight to WA for one. I dithered around for a coupla days trying hear and there then gave up on it a bit for a while to ponder my next move as far as procuring one was concerned, when by chance, I was looking around my shed for something else and noticed a Bilstein damper mounted on a fullly equipped front diff housing complete with Maxi Drive Lockers and axles, which I had obviously forgotten about. I took the damper off, bench tested it (it was good) gave it a clean up and re-paint, mounted it to "Vilet", took it for a test run and guess what "perfect" no more "Death Wobbles".

    Regards and thanks:-
    Patrick M

    It's alright but not what I would really like, it has to do the job and I do have a coupla interesting rigs but nothing like what I used to have.

    I would have thought that the 'death wobble' should not be caused by or dependent on your steering damper function.
    A tight steering damper may well mask it but the underlying issue could still be there.

    You may be right but whats to say Land rover didn't put them on originally to do the same thing (hide a "Death Wobble" problem even when everything was brand new? Apart form that while re-building the old girl everything such as swivel pin and wheel bearing pre-loads have been done, everything as I have mentioned has been up graded, the only thing that was overlooked was the damper. Even the brakes were completely rebuilt the calipers have new pistons new seals new rotors and more. Actually that was an interesting one when I pulled the old cylinders out of the calipers some were blocked up with heaps of gunk rendering the primary and or secondary circuits to a minimum of their actual capabilities. Rebuilding them made a huge difference.
