I used the same boots that Billy used when I bought my rodeo 6 years ago (just did the outers). No signs of cracking or breaking. Thinner is BETTER on outer boots because they have to flex a lot more then the inner ones. The dorman boots are much more flexible then OEM so hold up very well. I have since put them on 2 more rodeos.
I tried to get my abs sensor out when I first did mine but it wouldnt budge. I didnt try hard enough to break it. Since then I just unplug it and remove the 2 brackets that hold the wires. Only takes about 2 minutes and you dont chance trashing the sensor.
