Bring a thread back from the dead (at least I search!

)
Mine is knocking, more predominantly on the right, but both sides over bumps and pot holes / cats eyes at low speed.
I was thinking ball joints, but as previous owner has fitted eibach lowering springs, not sure if something like bump stops hasn't been fitted the wrong way round, or if top mount bolts are loose.
Will have a look tomorrow, but wondered if anyone else got to the bottom of it, specifically AndrewJB?
