    Default woble>?

    ok guys so my brakes need replaced both pads and disks on the front, after some high speed runs with heavyish breaking i noticed the steering wobeling some, could this just be warped disks?
    ive got clunking still from the front which i think may be the steering rack (not sure) so wasnt sure if that caused the wobel or not..
    any suggestions?

    a difficult one really without experiencing it "yourself" so to speak you would need to find a perfectly flat piece of road and try the same braking manouver several times to rule out warped discs because it could be that dependant on suspension set up/wheel tyre pressure etc that the car is following the undulation in the road surface

    is the vehicle only wobbling under heavy braking - or light as well?
    does it do it all the time or only when the brakes are hot ?


    regarding the clunking - it may be related ??

    but as its a braking issue and brakes are saftey related .... you can do no wrong than going to a a quickfit /nationwide type operation that is offering a free brakes/health check and getting a "professionals" opinion

    i noticed it yesterday with 3 passengers in the car on flat road approaching a round about, i havnt noticed the woble at slower speed only when braking hard from high speeds..
    my brake pad light is on so im gonna shange the front disks and pads anyway and see if that helps..
    any suggestion where to get the set for my 05 cdti at a decent price?

    The wobble under braking could be that the discs are not seated correctly on the hubs. Did you clear any dirt and corrosion off the surface where the disc seats on the hub before fitting the discs?

    EDIT - Just re-read your post and it does sound like the discs have warped. I thought you had replaced them yourself. Just my opinion, though.

    As for a clonking front end, I changed the front anti-roll bar drop links on mine about three weeks ago and it removed almost all the sound effects from my car's front end. It still crunches ever so quietly but I think that the noise is coming from the front ARB mounting rubbers. These are known for drying out, apparently. A little grease can help with this but I have not bothered, to be honest. It is only noticeable when the car is cold and has not been driven more than a few hundred metres. After that, all is well.

    I hope this helps.

    Mine was "crunching" over speed bumps particularly, but also over large potholes, not that we have many of those on our roads. The ARB drop links have helped considerably, almost eliminating the sound. I think that any remaining noise is the rubbers. I shall do those one day...

    As for your "clunking," that might be a different problem. The drop links were only about £9.10 each from LMF, plus P&P, though.

    when i think about it, its more of crunching, for e.g. when im reversing into my drive stopped and turning the wheel the noise is thier, or when its going over some bumps or whatever, not always but usually.
    might be worth trying them then.,..

    It's easy to change them. There is an excellent How2 on this forum in the technical section. It only took a mate and me about an hour start to finish and the results spoke for themselves right away.
