Replaced the rear sway bar links, but rear end is still noisy. Replaced the left rear shock last summer, but I can't get the right rear shock off, the lower bolt is bent. Can a dead shock be noisy? Or does the loose clunk indicate worn bushings?

Are any of these bushings straightforward to replace? Just trying to figure out where to go next - take care of shock or look elsewhere.
