Arrgghh... knocking still there...
I'm struggling to get rid of all the front end knocking with my suspension - with knocking still coming front the nearside front when going over bumps.
So far the following has been changed:
Front and rear droplinks
Front shocks
Track rod ends.
Front ball joints
Rear shocks and top mounts.
I don't feel it's the front top mounts as the knocking doesn't sound high up - but any suggestions on what can be left that can cause it?
Many thanks.

Mine has a front knock too, but I've now given up wasting my time trying to find it..... Even a garage could not diagnose the fault.
The only thing it could be is one of my year and a half old BC coilovers have failed.
Is your knock only over bumps?

I think I've had most of the knocking/banging noises possible - lol. Each time I've had part of the suspension changed it's helped reduce the issue. The ball joints replacement got rid of a more metallic sounding knocking, whilst what is left is the standard suspension knocking - something that I would probably have thought was either drop links or the shocks, but I've changed both of mine.
if I was you I'd change the drop links first - by far and away the cheapest fix.

Yep, real pain. I did some testing over some speed bumps and with only the right wheel going over the bump then no noise, but with the left wheel only then the knocking is there - so side dependant for me.

Also side dependent for me, not that I can find it even narrowing down that close haha.
I can't simulate the noise where not moving as I can't put a great enough load of the car without the weight of the car.

Thanks. I'm getting to the stage where I've replaced most of the expensive items, so almost ready to replace everything else one at a time to try and clear the noise.

Try disconnect the front droplinks and go for a drive over the humps or any surfaces which normally cause the knocking. If no knocking then it could be the ARB bushes or bushes brackets or droplinks or even lack of lubrications on them.

Was the suspension you changed brand new?
What model is your car? My Sti shocks knocked but they're inverted and prone to it when the original grease disperses and or dries out. That's simple enough to sort if they are Sti shocks.
Also, what brakes do you have? Might sound odd but a lot of the aftermarket upgrades can be noisy. My AP's knock quite loud where the pads aren't the sort of tolerances as the OE setup would be. I have to keep them serviced regularly.

Interesting point re the pads - as I've had new discs and pads recently but my front left caliper failed so I replaced it with a non-OEM replacement and my front pads in that side (which has the worse of the knocking) do move about and make a noise when I reverse and brake.

Well, I'm going to get the front top mounts changed.
At the rear I've had the drop links, shocks and top mounts all changed and there is the odd knock still occurring.
Worth changing the front and rear ARB bushes too? I must be getting close to changing all that can be changed?

maybe a scottish thing...
I share your pain
I've an 08 hawk GB270 with a helluva annoying knocking sound from the front.
To date - replaced struts and springs/drop links/arb bushes and even started to strip the steering rack down thinking it might be the joints on the inner tie rods....
still no change - not a thing.
more louder from the drivers side going over bumps/holes but also a rattly type knock at low speeds if you turn corners - this rattly type knock is more audible on the drivers side but can also be heard on passenger side.
Completely ruining the car for me but I may need to live with it if I can't find the fault.
cant see any play in lower wishbone balljoints or outer tie rod ends, so running out of ideas to be honest.
Cheers - sorry I can't offer any advice - just a wee rant really.....

I can empathise with the annoyance - as any sort of knocking ruins the car for me. Just thankful I've managed to resolve it. Given what you have already done to the car then ball joints would be my next change.
