control arm bushings will do this. axles will click, not clunk. and very rarely does an inner cv joint fail unless youre as low as me, or are making way too much power for them. the only thing to worry about with axles normally is your outer cv joints. they will click when turning and accelerating. another possibility is transmission mounts, but most likely as i said control arm bushings. it's very common on these cars. sway bar end links will only cause a clunk when going over bumps. trust me, i am very familiar with the suspension on these cars considering i've broken and rebuilt just about everything.
