Urgent - Top Mount Loose?

[Kosy]

Hi folks,

Noob question time. Car just back from having suspension refresh and work.

I've gone to give the bay a quick clean and noticed that f/o/s top mount (outer piece black rubber) is loose and can be spun with my hand? Other side is tight as I would expect.

Should this be tight? Car has had geometry and everything done. If I tighten this will it affect geo?

Thanks

spinning on the nut?

spinning on the nut?

No, whole top hat thing spinning as one piece up and down that bolt.

I've found something saying it should be 20nm?

needs tightening up, could of been forgotten if it's been off recently?

Thanks mate. Yep, must have been forgotten!

Tightened and all good. There was a light knock coming from it which is now gone

Just done all my shocks and springs and have this issue on the rear but won't tighten any more, making knocking noises
