I have a feeling he's talking about the top mount (rubber) that doesn't even pull off, it'll either fall off or stay in the chassis as it's only a buffer.
If we're talking about the top mount bearing, slightly different story that involves spring compressors
Job done but looking like I'm gonna have to replace the dampers. The bearing must have been gone for a while as it had worn into the threaded end of the damper. I spaced it out this time so as I could tighten it back up but I really don't trust that one now
