I would change all rubber mount's and bushing (trailing arms).

It would be convent to also change the brake lines at this time.

Be sure to mark right and left side on the trailing arms. There is a difference.

I cleaned and painted everything.

Enjoy the new and quit ride.

Yes those are good items to change if  you do not want to get very invoved. Also consider changing the rubber mount in the trunk. The front pinion seal is a frequent source of leaking fluid.

More involve is plan "B"..... you really will  get involved. Change; the inner and outer axle seals,  the outer axle bearings, the rear axle boot with a solid one, check or replace the horizontal rubber mounting tube (at the swing axle). Replace the rubber O-ring grease seals at the swing axle. Consider replacing rubber spring pads and replace the rubber bushings at the trailing arm/ axle connection. You end up with about another $1000.00 in parts and a lot more work for plan B.

Having done this job last year (and my switch out and others are well documented in some excellent threads here) I would strongly recommend plans A and B. Youll only do it once, so you might as well go balls out. It'll be worth it.
