Rotor Lug Nut Hole Size

I have had a popping noise going on for some time now that is driving me CRAZY. I cant seem to figure it out. It happens when I first take off and is worse if I stop hard and then take off again like there is some play in something. I have checked out everything in my suspension and driveline because this was my first thought. Nothing seems to be loose that I can see and greasing the joints (have a Rubicon Express Superflex kit on my jeep) didn't seem to help any. So I have just kind of dealt with it and kept an eye on it.

Yesterday I decided to rotate the tires and think I may have found the problem on the front end. When I pulled off the tire I noticed that the holes in the rotor for the wheel studs are much bigger than the studs themselves. The studs are 1/2" studs and the holes are like 5/8". So my question is, are all rotors like this or did I get the wrong rotors? I replaced the rotors and hubs about a year ago and I have found that there are different types around my year model (2000). The reason I think this may be my problem is that there are shiny spots on the rotor and the wheel like they have moved independently and the wheel holes are burred like it has moved.

I didn't think to take a picture but I might pull the wheel back off tomorrow to post a picture to help explain the problem. What do you guys think?

Not entirely sure but that may be the problem. Were your hubs OEM or aftermarket? Pictures will help.

A BTT for you to see if someone else has any ideas or answers.

you still have the problem after taking the wheel off? Believe it or not I had something very similar to this when I got my tj back from shop when I got my free rotation.. day later it was making similar noise as yours. I was checking everything, then what do you know I get the lug wrench out to take the wheel off and the lugs had barely any resistance.. I tightened them up to spec and what do you know. No more sound.

Sounds like your problem last longer so probalby not the cause but its one of those Q:"my car wont start whats wrong" A:"check your gas" suggestions lol

I wouldn't think it would be the rotors...

Have you checked inside your diffs lately?

Lug holes should be about 9/16". They're hub centric not lug.
'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.
