Just wanted to let everyone know that I went to napa today to order the centering ball kit part # 211355x which is for the Dana spicer part, napa no longer carries it. So you need to use the precision brand part # 607. I ordered mine today will be in tomorrow. It was 77.00 bucks n some change. If this had already been posted then sorry, was just way to work n didn't have time to search it. But if u want the spicer brand u can still get it online, I found it on all jeep.com for 48.50 that was the cheapest.
