Pretty easy install. Remove upper ball joint nut, remove camber sleeve that's currently in there, install adjustable sleeve. Sometimes the sleeves are a pita to get out. It'd probably help to spray penetrating fluid on them for a couple days before you're doing the job.

There should be a chart with your new camber sleeves that outlines what number/letter to set them at to get zero degrees. Install them at zero, check the camber angle with an angle finder, then set the bushings where you need them. Use plenty of anti-seize when you install them.

I got mine at Rock Auto.
