The replacement suspension springs were easily installed using the video tips. The video was absolutely essential for the rubber boot replacement, as the written directions that came with the kit were poorly illustrated. Also essential was the large spring clamp mentioned in the video. The boot installation was a bit difficult at first, even after watching the video, and then went pretty quickly as I developed my own techniques. Also helpful was an able assistant aiming a flashlight just where I needed. I am very pleased with the results as everything is working perfectly. I LOVE THOSE INSTRUCTION VIDEOS ! APP is a great resource for the the DIYer and has made every repair project satisfying for me.
