I started to do my own, but after surveying the task decided to let Camping World do it. I didn't have all the proper lifting equipment - that was the main thing that made the job look easy. They used two large hydraulic lifts; one on each side to the rear of the axles. Lifted by the frame. Then put large jack stands under the frame on each side for safety support. Then they used the rollaway hyd jacks to support the axles after first removing the wheels. He pounded out the nylon busings with some sort of punch, then pressed in the neverfails with a block and hammer. He did the whole bushing job - two axles, in about an hour and a half.
