The concept of removing a wheel and putting spacers on the wheel hubs was something I couldn't do at home. The ring nuts were tight and I couldn't get them out. I took it to the shop and unscrewed the nuts with no problem. However, the wheel bolts on my 2018 Jeep Wrangler Sport JL were too long. I had to cut them to fit my wheels on the spacers. Otherwise I like the blue color of the seal and the nice look of my jeep.
