I did our trailer and the hardest/longest part was getting the trailer blocked up to get the axle off. I did purchase the kit thinking it would make it easier but after doing it I can see all you need are the saddles if you can weld. After getting everything lined up and a simple tack weld it all went back together fine and the alignment measured out perfect. I did not have to extend any wiring, lucked out and had more than enough slack.
