Ball Joints

[FlipRS6]

My 2 upper ball joints on the drivers side have gone bad, would you guys suggest replacing all 8 or should i just replace the two that have gone bad?

There is no real adjustment to those so I would just replace them as soon as possible and then plan on doing the lower two in the next year or so. The upper rear one is the one that tends to wear out first on the C5 cars. The rubber is crap but at least it isn't too expensive. I would go with the Meyle or 034 motorports arms as I think there rubber is a little better than the Bilstein/Febi or the other aftermarket ones out there.

i think i might go ahead and do all four on the left after getting your input.... should i go ahead and do the the 4 right ball joints as well?

You should do both sides together whether just the top two on each side or all four on each side. If the left is worn out then most like the right is too.
