Be sure and check all the suspension links bushings- five links on a side, ten bushings per side.
Look to see if the differential is leaking, a good time to do the seals.
While the whole assembly is down, replace the rubber flexible brake lines.
Check the axels and make sure they do not need repacking, and also check the rear wheel bearings.
