Hi, I've just replaced shocks x 4 and springs x4 on my w211 03' avant saloon (sachs), but ride is still incredibly bumpy. Do the shocks bed in after a while? I did adjust the height on the front shocks with the circular clip to match the height on the original shocks. This distance being bottom mount hole of shock to base where the spring sits. Have I missed something out here? Any ideas? cheers.
