Thumbs down My wheel fell off. Rotor question

Hello guys and girls. Quick question. Yesterday I was driving through my neighborhood and somehow my lug nuts backed themselves off. My wheel fell off and my rotor dug in to the road. My question is would it be safe to get the rotor turned and have a flat spot or would that cause vibration? and if i go to replace it do i have to replace the hub assembly with it or can it be just the rotor. Asking because bj's sells rotor with hub assembly.

and one other thing. Where does the vacume line for the front Dana 44 on a 80 cherokee laredo connect to? Mine is just there.

If your rotor is thick enough to keep in the first place, I would rotate it to see if it's true and inspect for cracks. If it's straight, I would smooth out the flat spot and then break down the hub assembly and check the bearings for damage. Either way you have to remove the hub to get the rotor off. You can get just the rotor if need be and the hub is in good shape. Just make sure it's not the $12 cheap china one. How is the dust shield and the lower ball joint?

Don't know about the vacuum lines.

There is no vacuum line on an '80 Dana 44. There is a vent tube, it attaches to the top radiator mounting bolt on the drivers side.

The rotor seems messed up to me. and i priced the rotor at autozone for $22 and then at napa for $41 The dust cover it dug a hold in the bottom of it. Im not worried about that. Ball joint is fine as well. O and it snapped off one wheel stud as well.

I would replace that rotor and probably the other one as well just to have a good set on there and avoid possible pulling to one side.

New studs, and use a torque wrench when you put the wheel on.
Over-tightening of the lugs may have caused the failure.

The dust shield can be banged out, personally I tear them off and toss them, seem to only collect gravel for me and make noise, but that's my preference.

Check for stripped studs, replace if any doubt about them, cheap parts.

would replace that rotor for sure. Rotors are balanced when you buy them, plus that one looks really bad, wouldnt trust that trying to stop such a big vehicle

If you rubbed a flat spot on one side of the rotor, it is not balanced and will cause vibration at highway speeds.

That flat-spotted rotor will be just fine as long as it's not cracked, which can be tough to tell. Balance may be a wee bit off, but probably not by enough to matter. In any event, the generic rotors from NAPA (Brembo, I think) are a pretty good value. I have no experience with anything cheaper.

Those lug nuts didn't just come loose suddenly -- got any ex wives?

I got to agree with S.J. Wheels don't just fall off. I'd find out why this happened. And normally, if a wheel is loose and not very tight against the wms, you will feel/hear it wobbling around way, way before the wheels just falls off. Did you see any lug nuts around? How far had you driven that morning before the lug nuts just fell off?

something is fishy here.............

Mine choose for me and rusted off

New axles does not appear to have them.

As for lug nuts backing off: As someone who wheeled with crappy street tires for a long time (and thus changed a lot of tires on the trail) I can tell you that if the lugs are wet or dirty when you put the lug nuts on they WILL loosen over time. I ALWAYS check my lug nut frequenty after they have been removed and have started using lug nuts without a top now and put a bit of electrical tape around the lug that way if it DOES come loose somehow at lease it will be harder for it to back all the way off.

Did you just do,or have someone rotate your tires? It must have been beer-thirty before that one got done.

As I said before, I just bout this truck over the weekend. Drove it 700 miles from pensacola FL to NC. It drove fine all the way here. And as far as feeling the wheel wobble. I did not feel it wobble at all. Just remeber the truck drop and drag and remember seeing my wheel bounce across someones back yard. I'm. Just going to replace the wheel studs on every axel and get a whole new set of luggs with a key. I was doing 75 80mph down I-95 and I-10. I'm glad it just dident happen there. Ill post pics of my new truck and a brief intro tonight. So look for it

Yeah I think someone played a horrible joke on you. Those lug nuts were removed or at least loosened.
Solution to problem: Chain one-eyed, one eared, three-legged pitbull to front axle with long chain.

There was another FSJ in P-cola and I didn't know about it? WTF? Were you on Corry Station? I'd get new rotors. Wouldn't mess with a rotor that's been drug across the road.
