its probably the drop links as the rubber shrinks and causes the anti roll bar to move around. There not much from subaru, think they where £18 each but i'd upgrade to some whiteline ones there much better.
I have a knocking noise from what i think is the wheels but the wife is sure its the middle ....even the smallest lump in the road sounds terrible.....
I've got to ask this, even if it is obvious: you have checked the wheel nuts are tight, haven't you? Also, no tools left lying around under the bonnet (or a bag of last year's dried up conkers in the glove compartment).
There is a long bar (sway bar) under the front of your car. It runs from wheel to wheel. There are links that connect the bar to the suspension on the wheel. Those are the drop links, or endlinks. They need to be connected well to the bar and the suspension components (control arms).
Cheers mate ...How can I tell if thats the problem ??
I think you need to get a mechanic to look at this. If something's coming undone in your suspension (or is already undone), now is not the time to be learning about your car while you continue to use it.
To test if its the drop links, get down under the front of the car - you shouldnt need to jack anything up. There is a long bar (anti roll bar) which goes from wheel to wheel which connects the the suspension and looks like a stretched 8 and bit like this
these are the drop links, if they are shagged then when you move the anti roll bar they will move. If they are shagged then they will move noticably.
