Fiat Punto n/s suspension noise

If excessive wear on driveshaft , you will be best to replace that and also check wheel bearings .

if wheel bearings knackered it would get louder the faster you go,could be coming from gearbox

If it was gear box unlikely to disappear at higher speed ? Suggested checking bearing for the excessive movement mentioned which would allow disc etc to move , not for noise .Bearing noise is normally droning increasing with speed .

I have a knocking noise from the underside of my fiat punto-sounds like its coming from the drivers side or centre-I have had both lower suspension arms replaced/anti roll bar end bushes also have been changed/rear engine mount/gearbox mount was knackered so that was changed-wheel bearings have been checked,they are okay and the exhaust has been checked for any movement but again this was okay!! it only happens when you turn hard left or right NOT in a straight line or over speed ramps-it used to be a lot noiseier but the work done on it has reduced the noise but there is something still knocking underneath and we just cant seem to find it-any ideas what it could be as this is driving me mad!!! its a 2004 punto 1.2 active

knocking/clicking noise on left or right hand lock is normally down to outer cv joints,have these been checked?have you checked the front strut top mounts for excess play and wear?
