Can someone cofirm if the front lower ball joints are the bolt on are press in type. The look to be bolt on type so looks like an easier job to replace but am looking for advice from the pros here please. Also is the DTS suspension considered to be "heavy duty suspension"? I see many spspension parts noted as "except heavy duty suspension " but no indication of which cars those are, even when I've listed the car as 2000 DTS. Was this an option? No idea and just want to make sure I'm getting the correct parts. Thanks for any / all comments. Ball joint Q is the main.
