Replacing Rear Bushings

M151 or M151A2 - The entire A- Arm needs to be removed from the vehicle, and put on a work surface. Trying to do this while on the vehicle is a waste of your time. The old bushings will need to be cut out, they can not be pushed out, don't try . Again trying to push them out is a waste of your time. Below are methods used by myself and others that have been the least path of resistance.
