Many members have replaced just the boots and not changed out axles, half shafts, jack shafts (pick whatever term works for you ... ... we tend to use the terms interchangeably). I've attached the file for replacing just the boots. BTW, I ended up just using zip ties instead of the metal bands with very good luck.
Oooo, Iccckk!!!
Dorman didn't last any better for me than MechaTech. I ended up just using AutoZone that looked much like OEM & they lasted & were cheaper.
