    Default Suspension change - now a knocking noise

    Hi guys,

    I've finally managed to change my suspension over to the Eibach springs and Bilstein B4 shocks.

    Just finished it tonight, and took the car out for a spin.
    It was fine for 3 streets, then when I was going round a mini roundabout, I heard a noise on the passenger side front. Just off the roundabout was some speed bumps (i'd gone this way on purpose to test the suspension). When I went over the first couple of speed bumps, there were weird noises coming from the front passenger side.

    It sounded like something was about to fall off somewhere...

    I pulled the car in, and double checked everything, Nothing was loose, nothing had been missed off. I did notice that the front was lower than it used to, and it may be that the wheel is touching the wheel arch when I turn corners or go over speed bumps.
    I've never had the wheel touch the wheelarch before, so I'm not sure on what it sounds like, but thats the only think I can think of it being.

    Can anyone suggest anything, or has had this problem before?

    I've got 18 low profile wheels, if you need to know that..


    Thanks
    Dan

    Top strut bearings possibly. I changed my suspension, lowered springs and Bilstein dampers and the extra stress brought out the noise in the bearings which were goosed. Noise mainly came when turning the steering

    They're cheap mate, think it was about £18 at trade. Only problem is the suspension has to be taken apart agin

    When you had them apart you'll have noticed the plastic part at the top of the strut that spins to allow for movement when steering. It goes between the spring an the plate.

    Used your pic to try and show you. Of course I can't say for sure it is this, but it is very prominent when turning the steering.

    The only way to know is to change them over as you can't check them when they're off the car unless you can replicate all the forces the car puts on them. I thought mine were fine because there was no noise when turning them, but they had no weight against them at all, even standing on them they sounded fine. Sorry to babble on LOL.

    No thats fine, very helpful!

    I did just swap over the old ones because I didn't get any new ones, just new springs and struts.

    Do you know the part number for it?
    Is the car safe to drive until I get chance to replace at the weekend?

    Thanks, you're a star.
    I'll order 1 or 2 tomorrow.

    I'm just annoyed I've go to go through taking it apart again. It was such a pain in the ..... last time.

    Oh well. Only way of knowing if thats it, is to change it.


    Cheers

    Have you got the sleeves on the bottom of the spring as well? And some grease in the spring seat? That's the only other things I can think of it being.
