good afternoon my name is ***** ***** I will assist

ball joint will not cause this type of noise. it will give a knocking noise.

if the noise is related to suspension, which could be a bad wheel bearing, it will change with road speed, that is, it will get louder and softer according to road speed. if it is engine related, it could be a failed bearing that the drive belt is turning. this can be determined by reving the engine without the car moving to see if the noise is there.
