Thought of that as well, but the rotor itself simply slides over the axle housing/flange. If I was to tighten that big ol' nut(even if I could), I don't think it has anything to do with the loose rotor...so, if I tighten it a) I don't know if I should(don't know what ft lbs the max is) and b) I don't think it'll push the rotor flush against the hub.

STILL CAN'T RESOLVE IT! haha....all though I'm almost there!

 

Ah gotcha at least you found the source

 

So as stated, the squeak is still there... It seems my rotor isnt sitting flush enough against the hub and it has the slightest of play where the rotor slides onto the axle housing/flange.

All this is leading me to believe that in fact, it is a bent axle flange on the outer passenger axle shaft. Obviously, you guys aren't hear to literally look at it/hear it, but what else could it really be? I mean, it makes a different sound that what a caliper/brake pad would make, it's the exact noise when I pull and push the rotor, its scraping....

I also set up the guage on the knuckle and tried to see if there was any indication of a warped rotor, but the dial didnt move at all... so again, lead me to believe its not the rotor rubbing on the brake pads/caliper, that its gotta be what I think it is, the inner opening of the rotor scraping on the flange...

going nuts am i.....

 

The flange on the front is part of the hub/unit bearing.. U might need one of those.. Since u have a dial indicator take the brake and rotor off and measure the run out of the hub flange and see what u get.

 

Good to know it's part of the hub(or maybe it isn't!). Again, the rotor seems to be scraping on the unit hub(now that I have the proper terms) right where it slides over the flange. It's that additional "play" thats not letting it sit flush and in essence "wobble" in and outward and rub and squeak...

Let me ask this..... if I run it like this for a while (been squeaking for about 4 months now anyway), what's going to be the most extreme problem that i'll run into? I know something is slightly off causing it to rub, but all lugs are properly torqued, rotors were warped, etc. So it leaves the flange like I said, or now the possibility of a bent hub.

 

the rotor should sit flush on the hub when the wheel is on. u can apply a bit of anti seize to the center of the hub where the rotor slides over the raised part on the hub. do u have the correct lugnuts for the rims u have?? reason i ask is some wheels have a different pitch on the cone in the wheel lug holes, and need the correct lug for that angle, or atleast thats what i know... maybe when u tighten the wheel its not fully tightning down and inturn the wheel is slightly loose??
can u make it squeak if u jack the squeaky wheel up and spin it by hand??
maybe there is rust build up on both the rotor, and hub causing it to not sit flush??
u can use sandpaper or a wire bursh or a die grinder with a "cookie" abrasive disc and clean the rust off if there is any.

 

Name is Joseph btw....or Joe, whatever you wanna call me.....

Regarding the correct lugnuts - I bought my set of wheels from a place that sells a lot of Jeep products, so I would hopefully assume that they gave me the correct size. However, I will say(as posted earlier), the style of my lugnuts has more of a ovaled/ball-type end. What I mean by that is the inside of the lugnut doesn't really go "deep". Thread is also only about an inch or so I'd say. So I said, perhaps the lugnuts are just bottoming out. I trimmed the actual lugs a little bit, the the end of the unthreaded part - about 1/4'' perhaps? Sure hope that wasnt a bad idea, didnt really see it being a problem. I did that in hopes that the lugs push the wheel back more to push the rotor flush. No go though....

Yes, I jacked it up and spun by hand....no squeak/visual issue. even had my brothers friend who is huge spin it, still nothing. Both tires spin the same amount as well with the same amount of force. Doesnt seem to be any more/less drag on either tire.

I believe thats what it is....the wheel is just tightening, but not the rotor to the hub....and I'd like to think it was perhaps the lugs themselves, or too short of lugnuts. Backspacing on the wheels is 4.25'' but I'm pretty sure that doesn't mean anything.

I haven't actually taken the hub off to check, perhaps that will be my next weekend adventure.

 

This may have not fixed his problem, but it did eliminate mine. I did what you suggested and all is quiet now, THANKS!

Its 100 ft pounds. I had a rotational squeak in the front end that was driving my crazy, I went through everything and it ended up being that big axle nut I tightened it up to spec and my squeak went away!

 

Another thing, if that big axle nut is loose there will be enough play between the axle shaft and the unit bearing to cause a metalic squeak when your driving, even if your lug nuts are tight.
