Well, some list it as a spindle, some as a knuckle. Go figure. Same difference, I guess. Miller Import Parts listed it as a rear spindle. Looking for a replacement, I've learned to be prepared to see it listed either way. As far as the bushings are concerned, I had enough time during lunch to call Energy Suspension. The kit comes with all the spindle/knuckle bushings, trailing arm bushings, and upper control arm bushings.
