It would really help you if you can find a good local, and honest independent Honda shop near your to work on your E, instead of relying on the dealer for work. For 3k, you could probably refresh the entire rear end. From the photos, it looks like most of the bushings need to be replaced, instead of the knuckle. Also, does your E seem to sag and the top of the wheels toe in, when you look at it from behind? If so, and you change out the control arms, you might consider going with a set of adjustable arms, to assist in future alignments. Struts and rear differential mount ( if AWD ) may also need attention. Keep us posted on your findings.
