I'll be swapping out the stock shocks/struts on my w124 for Bilstein sports and will be doing it myself. Just wondering if you guys have any tips or precautions to save me any possible headaches/repairs if I happen to mess it up. One serious question though, are the shocks and springs independent of each other? In other words, the shock/strut does not keep the spring compressed right? Just want to prevent a spring from flying out from the car when I remove the shocks. Otherwise, the swap looks pretty straightforward. thnx in advance.
