    Hi all,

    This morning when driving home from the shop for no apparent reason my 2002 S3 made a loud bang, sounded like something snapping from the front of the car, drivers side. So ive just taken the wheel off, and cant see anything out of the ordinary. I then put the wheel back on and as i turn the steering wheel from left to right i get a bang, followed by a kind of twang (like something rattling and vibrating). This happens when turning left to right, and then right to left, at approx halfway through, so near enough then the wheels are straight.

    Any ideas before i put my car down the extremely tight drive and over the pit? Sounds like something catching, but just wanted some feedback as i cant get my car down the drive for a few hours so just looking over the internet for the time being.


    Cheers,
    Ash.

    +1 broken spring. You might not spot it right away since its usually the bottom coil, run your hand around the bottom of the spring. Careful it might be sharp where its broken!

    Yeah after i looked again i found the bottom 3" of the spring had snapped and was sat loose in the bottom housing.

    Does anybody have an ideas about taking the shock absorber out? Ive got the wheel off and taken off the 3 top mount bolts from under the bonnet, but looking at removing the bottom of the shocker, do i have to take the brake disk off? I tried searching for a guide but couldnt mind much.
    Cheers.

    Its on a pinch bolt on the hub, undo that and it should come out,you may need to take the ARB linkage off too, you will have to open the clamp up a bit to free it, be careful not to trap or pull brake lines abs sensors

    oh right, cheers for the advice. ive taken the pinch bolt out, but the shocker was still solid so i guessed it wasnt just that holding it in. Looks like ill have to waggle it a bit to try get it loose then. So is it really as simple as 3 bolts for top mount under the bonnet, and then remove the pinch bolt at the bottom? (ovbiously also remove any linkages attached to the shock).

    No, its the single nut with the 6mm hex in the centre that holds the shock on. The 3 bolts only hold the strut brace on.

    You'll also need to use a speader on the hub carrier to strut to free it up.

    The tool Ive seen goes in the gap then when you turn it 90 degs it gets wider, you can use a allen key, tap the nearest size into the gap then turn to the high points. Just be careful as it might slip.

    Also soak the bottom of the shocker in good old wd40

    raers are really easy, undo the shocker bottom bolt, think you have to undo the ARB drop link and then just make sure back end is jack securly and then push rear trailing arm down to remove spring the old one will probally have the top loop missing as they often break.

    Clean everything up and the lowering spring should be easier to refit as its smaller.

    A doddle compared to the fronts.

    Cheers for the advice,

    Got the car finished last week and its looking good. I ordered Apex 20mm springs, but 30mm ones came so i fitted them anyway.
