Citroen DS4 a rattling. and clunking noise under the car. all suspension. parts replaced still makes the noise

You don't list the anti roll bar bushes which are often a common cause of clunk / knock

Thanks I have looked at the bushes and had a crow bar on them and they seem good I’m just thinking about a drive shafts when i purchased the car three years ago a month after the left outer drive shaft boot circling had come off I don’t no how long it had been off with the last owner. but that was three years ago but I only do 3 thousand a year? Could it be

If the gaiter was off and the grease thrown out , the c/v joint will be worn if driven in that condition .If you grasp the shaft and and the joint you can usually feel any wear .

Thanks il check that out what sound would a wheel bearing sound like the clunking sound is sort of a deep type sound. ? thanks

A wheel bearing is a droning sound that usually increases with speed . If a c/v joint is badly worn , when you turn on full lock and load it , you get a clicking noise

Thanks I have a mot due I hope they’ find something il let you know thanks for your thoughts some times I think it’s coming from the rear end?

Hi,
Did you ever get to the bottom of this noise? My DS4 has exactly the same issue at the moment.
