Hi. Got a 2003 blobeye wagon wrx , had classic shock knock. So replaced with some coilovers I had just to quieten things up a bit, but now ride is a bit harsh, what causes this shock knock? .is it the top mounts? Or the whole strut. If I replace the top mounts and replace original shocks will I have solved the problem,or are completely new shocks req,d. Thx
