    [Discovery SII TD5] Death wooble on left turns at braking

    Hi,

    I found these videos on youtube that explains a little the problem that I have.:

    [ame="http://www.youtube.com/watch?v=vwiv23dLhMY"]YouTube - Death Wobble[/ame]

    [ame="http://www.youtube.com/watch?v=x7cEOPYQFTs"]YouTube - Death Wobble[/ame]

    When the problems appear ?

    - Firstly, to comment that the problem appear AFTER a slightly lift, from standard to 1.5".
    - When I full brake, specially behind left turns on road at speed.

    Thanks in advance.

    pd: I have searched for 'wooble' and I do not have founded yet again in the forum.

    Steering damper would be the first thing I'd be looking at.

    G'day,
    After Redback's idea have a good look at things as it sounds to me like a caster problem.
    Are all your bushs ect. in good condition?
    Had a front end allignment since the lift? I know toe-in only but whats the angles?.
    Was a tie rod removed for the spring fit?
    Put a spanner over all the front end.
    Mostly just thinking out-aloud.

    Cheers.

    Firstly, thank you all.
    Well, this week I have maked an alignement and puted the front anti-roll bar. Surprisingly, the death wobble is now very light but it's here. I am waiting to put a winch and perhaps, with the higher weight at front the posible caster problem will disappear. If not, I will unmount de lift and re-mount the original springs but in Heavy Duty specifications, and stay on standard height.

    Try the word "shimmy". will give lots of results.
    Lift + braking = shimmy mine does it but very slightly. Use a very good after market steering damper and if its is still a problem change the castor.
    ie. With offset bushes or after market radius arms.

    Have a good look at the Panhard rod bushes.

    Mine got so bad about a year ago after a hard off road trip, I had to hold the front end together with a Ratchet strap to get home

    I have changed the steering damper and the wooble i soooooo light that the problem practically is solved. I have anti-rool bar mounted on front now, and it seems that helps too.

    Look at your shocks and radius arm bushes too, they can cause a wobble if they are knackered.
