I've ordered the Eibach kit now, but have heard that the rears can be a pain to do, due to removing the bottom bolt which can seize, resulting in replacing the rear bushes, but which bushes are these, and should i replace them anyway?
I've noticed a knocking noise from the rear getting louder over time - thought it may be ARB links, but was gonna replace those too.

In short - which other bits can i replace on the back and front whilst the suspensions in bits, bar the struts, which i think are good...?
