Banging and Rattling Noise Under the Bonnet – Need Advice on Strut Mounting and Cooler Fan Fix

This banging and rattling noise is driving me mad! So, I booked my car in with Halfords, and after a thorough diagnosis, they reported that both front suspension mountings need replacing. The excessive noise while driving seems to be coming from those front strut mountings (not that old, mind you – they were replaced on 9th March 2024). They also mentioned that my cooler fan looks brand new but is missing its rubber damper. I’ve never had any work done on the radiator or the cooler fan, so this is all a bit confusing. The chap said it’s also rattling a bit and that I’ll need to get it refitted properly with the rubber housing. Does anyone know what a rubber housing is, and is it something I can DIY to make it fit properly? What parts would I need? For the strut top mounting, I’ve ordered Monroe. Fingers crossed this one does the job and finally stops the noise!
