You can drop the trailing arms pretty quick.
Remove the axle bolt or nut (depends on build #), Remove calipers and hang with zipties or safety wire and not from the brake hose..
Remove the upper outboard swing arm bolt (near the spring) and lower outboard arm bolt.
Remove the lower shock bolt.
If you don't want to fiddle with parking brake shoes, remove the nuts from the emerg brake handle and pull the cables down. Disconnect the Adel clamp on the frame holding the cable.
Pull the trailing arm out off the axle splines and aft to remove.
While you have it apart you can replace some of the bushings with Polyurethane types if you desire.
This kit will do all the rear end bushings and rear hub bearings.
