They say that if you lift your jeep more than 2.5" you have to replace the front drive shaft. I'm running 5.0" and still running my stock one. I know it's going to give up the ghost soon. I figure its a 2013 JKUR with 10k miles. I should be ok another month. After that, I will look into replacing the front drive shaft.
You didn't say anything about the steering stabilizer nut coming off. I was trying to figure out why you are getting a noise at 60 mph on the freeway. You wouldn't get that noise at 60 on the freeway with a rock in your breaks. That only happens when your going slow.
