Dropping rear suspension as an assembly

I do it regularly, lol.

Jack the car up as high as safely possible and support with stands - this gives you room to slide it out. Unbolt driveshaft.

1) Unhook brake cables first
2) Unhook brake lines/vent tube
3) Support rear and remove lower shock mounts
4) Unbolt all 4 trailing arms from the frame
5) Install 1 lugnut on each axle to keep drums from falling off - finger tight
6) lower jack with assembly resting on it (be sure to catch the springs as they fall out) and slide the whole unit out with the jack

As long as you can slide it past them, it should work fine. Looks good!

The front of the chassis is supported by two, 6 ton, 24" tall jackstands and the knee wall at the rear. The car sits level and there are at least three (3) 3.5" long drywall screws from each direction at each joint on the rear stand, so unless there is an earthquake here in the Ohio Valley, I doubt the car will be going anywhere.
