I know George MacDonald answered this question a few times already but I am
still curious about the creaking sound coming from the rear suspension. He
suggested spraying with water and greasing but added that was just a
temporary fix. That creaking is driving me nuts, what is the permanent
solution? New springs, struts?

I also heard about the balljoints seizing and snapping (saw the pictures on
TeGGer(R)'s homepage). How do I check if they are ok or not?
