    Default Wobbles

    Hi guys
    just wondering your thoughts on what happened on the convoy trip to Baal Bone on Sunday.
    We were on the bells line of road in convoy, DD setting quite a mean pace. At about 90km/h around a sweeping bend the road surface got a bit rough. The back end started shuddering really badly, and started a 'wave' of shuddering energy that moved through to the front and shuddered the steering wheel in my hands. After the shuddering wave passed, the car was a bit unstable and eventually settled down. This happened twice more on bells, scaring the bejesus out of me. The car was fine for the rest of the awesome day, we weren't driving at those speeds on the uneven Tarmac anymore. We went home via the great western freeway to avoid bells and the trip home was fine.

    my 2010 JK unlimited sport is completely stock, only has 40k on the clock and was purchased second hand from SVM Roseville.

    I am thinking of taking it to pedders for an inspection

    :O I thought I was alone... otherwise I would have backed off... I did see you @ Lithgow but thought that you kept on the GWH (being that you were stopped at the lights ) Apologies for scaring the bejesus out of you!! I almost lost it on that road on the way home also, some a*s*h*le decided to speed up when I was overtaking them - hit a bad patch on the road and was all over my lane and some of theirs... I'm most likely going to Bilstein shocks much sooner rather than later!!

    This goes for All people on a trip. If ever your in a convoy and you feel uncomfortable just get on the radio and let the trip leader know, we will only go as fast as the slowest car, likewise on the trail if you feel unsure of ANYTHING jump on the radio and we will talk you through it or around it. Don't feel embarrassed by getting on the radio its not a competition or a race, we are all there to have a good time, Safely. If in doubt read Convoy Etiquette, its on the website. Hope this helps you guys, And Rich, death wobbles are very common on JK's around the 40K mark, im expecting mine any time now. The Joys of Solid Axels.. Cheers Doggy Dave.

    Understood and noted DD thanks. I have indeed read the convoy procedures, a few times.
    Because the situation settled down each time I was ok to keep on, but if things were any worse I would have shouted out.

    Aw man, death wobbles. I read about that when I bought the car, never thought I would have to deal with it with a stock well looked after JK.

    Any suggestions where to start, bearing in mind I will be looking to professionals to repair.

    As others have mentioned there are a few reasons for wobbles/shudders in a JK, and at 40,000km and 3 years old there's a good chance that at least the ball joints are completely shot, if not a few other things. Sounds like a trip to Wooders is in order!

    One other thing to consider is the standard shocks (if it's still stock). The standard coils aren't anything to write home about but they're OK (until they sag so much you're riding on the bump stops!) but I found the shocks to be way too stiff and this caused some frightening moments hitting rough surfaces mid corner. Get some new shocks and all of a sudden the suspension actually soaks up the bumps and doesn't shake the steering wheel out of your hand.

    By DD - do you mean Doggy Dave or Dan D ??

    As Paul mentioned above re the stock shocks, they are my next item to be replaced - get your front end checked out though as at least it will be peace of mind for you

    Hey Dan
    i was referring to Doggy Dave, apologies for the confusion.

    Thanks for the info Paul, the shocks are still standard. I think I will take it to a suspension specialist to be checked out, maybe get the parts from wooders.
