I'm in the process of installing PSS9's in my 335i Coupe. Installing the rears was relatively easy. I've run into a road block with the fronts. I'm unable to separate the OEM shock from the knuckle that holds it and all the other suspension parts. I've removed the nut and bolt which appeared to hold the shock/strut to the knuckle, but the shock won't budge. Thanks for your help.
