    Astra + Speedhumps = weird noise?!

    Hi,

    My astra (2000 'W' Sport) has started making a bit of a weird noise from the front end when going over speedhumps and large potholes in the road. Now the car has been stood for a fair few weeks at a time as I'm at uni, so I'm not sure if it just needs driving or whether something more is up with it?

    The noise can only be described as a thud really. I've checked under the bonnet and checked that the bumper is secure and everything seems fine, but theres a bit of bounce in the front shockers when compressed. Does this mean their on the way out? Would this cause the thud when going over speedhumps?

    Cheers for any assistance!

    This will no doubt be the Anti Roll Bars mate, when they went on my car it made the same sort of sound.

    Here is a link to what the part looks like:

    Also known as "drop links". The rubber end with the nut splits and produces the noise when you go over speedbumps and potholes.

    They're drop links, I thought the anti-roll bar was something entirely different?

    The drop links tend to knock over bumps as you describe, cheap enough to get and replace.

    The bushes on the ARB can go dodgy and grate when moved, mine was doing that over speedbumps, easy enough to put new bushes in as far as I am aware.

    cheers lads, are they easier enough to replace? Looks to be only two bolts?! I would check myself but both the car an my haynes manual are at home!

    Cheers!

    The bottom bolts can be a bitch if their seized as there not easily accesible. I used an angle grinder lol.

    btw the drop links are wat hold the anit roll bar to the struts

    I've been driving the car over the weekend and it still bangs and crashes over speedhumps, but after a period of driving it just appears to quieten down? I haven't had a good look at the drop links yet, but how would I tell they need replacing? Would their be excess play i'm assuming?

    Also, I had a look in my haynes manual and it tells me to remove the front subframe?! Surely thats a bit excessive for changing the droplinks and ARB bushes?!

    Yeah, you dont need to remove that to take the ARB's off. It's one bolt at the top and one at the bottom.
    The only thing that you will need to do is jack it up a bit so it isn't so tight on the nut.

    The only way to see if they need to be replaced [I think] is to get them off. On mine the rubber part was ripped and there was severe play in them when compared to new ones.

    ok, cheers, I've just had a root around actually and it looks relatively easy.... I've found that it also creeks when the cars still and me and my dad bounce each side, would this also happen with knackard droplinks?
