Installed on my '72 Scout with no problems. Polyethylene bushings are much easier to install than removing factory rubber bushings. I recommend a ball joint service tool kit and an impact gun to remove the old ones, it makes the job easier. These bushings come with two packs of grease so you'll have plenty. Each set is designed for one axle of springs and brackets. You will need two sets if you have front and rear springs. I was a bit concerned that the rear might have a different part number…
