if my ballpoints
personally, i have never liker how most ballpoints feel, you can never beat a quality felt pen like a sharpie :shifty:
I would also look at your control arm bushings on your upper and lower control arms. They tend to wear over time as well causing a loud creak when driving. Ball joints will give you more of a clunk, like something is loose if they are bad.
Yes they can creek or squeak even with good boots. My '03 has Moog ball joints and they don't have any grease fittings.
