323 clacking noise in turns

[levi59401]

Hi, i have just purchased a 1987 mazda 323 for 300 dollars, i think it was a good deal, however it does have a small problem when i turn to the right it makes a horrible "clacking noise". I understand that this is most likely the cv joint, my question is when replacing the cv joint do u have to get a cv joint or just get a boot kit, the boot is clearly torn and destroyed. someone told me i just needed a boot kit but it makes a horrible noise, so i thinmk the joint may be bad, how do i tell? any response would be appreciated ty
