I actually did not have this conical washer. As the new assembly was 16mm dia. the old washer (14mm dia hole) didn't fit any more and there was no new washer in the Bilstein box anywhere.Originally Posted by Tiger
I understand today that this washer is taking the forces and transfers these into the rubber while without the washer the force goes straight into the center part of the rubber bearing and cracks it because of the high forces. this is the reason why the movement is so large and the cap kept popping off.
Bad thing is I asked the company selling me the parts for 3 months or more and they keep asking I don't need the large washer.
But after I can stick a screwdriver through the crack in the rubber everyone agrees it is getting time to take the assembly apart again and but large washer and new bearings in. Thanks for your input.
