Ok I know this has been covered I have a 2004 sti uk spec with a rear passenger knock I have replaced the suspension as it had coilovers and I had the noise knocking so now I'm running peddlers on a 4 corners also replaced front and rear drop links with white line parts so what's next to try to get rid of the noise

 

Check the rear diff outrigger mounting bushes for play/movement.

Also check that the underside of the bracket hasn't been bent up by somebody jacking the car in the wrong location in the past.

Had this issue on my car years ago, replaced struts, ARB's Droplinks etc... ended up being the above!!!

 

i was thinking next on the list is outriggers to replace its nice to hear someone else saying it to

I've looked and looked online but every one seems to fix the fault on the struts but mine have been changed so almost 100% certain that they are good

I went through this game of changing stuff for a while too. All new struts new wheel bear lateral and trailing arms. Turned out to be the outer cv joint on the driveshaft. Nightmare.
