Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

hi everyone my wife and i have had our corsa b auto over 5 years(more the wife's than mine, my motor is being restored using corsa to go to work and that) on a p plate real good motor always passes mot had some issues with emission's last 2 years but get it thru every time.
the prob i have at moment is when going over speed bumps there is a clunking noise and can feel it through the floor.
its not a loud noise just annoying , replaced struts and springs (from a corsa b deisel) fit new ball joints, pads,discs front hose's.
bought new springs to replace old one's when i removed springs the strut was buggered no resistance when pushing down on shocker so i have a pair of brand new springs for sale or swap, i need a drivers door (5-door) dark mettalic grey
cheers andy

Have you checked everything is tight or checked your cv joint as they knock when dry or bust

everything is tight checked it all , cv boot's not split so i would assume they still have grease in them, they have original clip's on securing them.
when it make's the noise i can feel it through the floor it makes sense what you say thinking about it, i was thinking of going down the gearbox mounting route ,to be honest open to suggestions
cheers
