Hi guys can anyone help I changed my suspension set up to coilovers because I had a knock and clunking noise on the passenger side of my 2004 wrx impreza and now the noise is still there?????? I've stripped the boot out and drove up the road with the boot proped open and it's not the sti spoiler which I thought it might have been please anyone got any ideas???

 

Nearside ARB bush or droplink??

 

Ensure the jack is secure and not moving.

 

slight play from one of the shafts.

 

I had the same problem . I took everything out of the boot including the jack and the spare wheel and it was still there . Next I replaced my noisy spherical drop links with brand new oem links but the noise still persisted . In the end it turned out to be the anti roll bar to chassis bushes that were badly worn allowing the roll bar to knock . Wish I had realised this before shelling out on a set of coilovers.

 

check the bumper, had the same on an old car which drove me nuts for month, turns out the bumper bolts were a little loose
