Second time this is wreckless. Both XJ's ive owned, both left rear wheels have come off while driving. Both have aftermarket wheels. Both have studs that are too short. Aftermarket lugnuts? What gives. This is the second time. My lugs are always torqued, I use a wrench and a flip socket. Should I just impact em on and smoke em tight?

 

Get longer studs.
Punch one out and bring to a parts store and explain your dilemma.

 

I agree with Dan, get longer studs, there's not enough material for the lug nuts to keep their grip on, make sure your using quality lug nuts, just cause their aftermarket, doesn't mean their quality!

 

Is this common? i have never had it happen, but did think my lugs looked short once i installed my Procomp wheels.

 

it a good practice to even after using an impact gun, to go over all your lugs with either a torque wrench or a legit turn of the breaker bar.... I also refuse to run aluminum rims on any one of my jeeps, too many cases like this

 

Torque them, drive for about 20 miles. then torque them again.

 

Make sure you are you using the right style lug nut for example cone seat vs ball seat, and make sure you have the right thread pitch as well. 1/2 inch versus 12x1.5 or 12.25.

Jeeps are factory 1/2 thread pitches and are CONE SEAT. I've used Gorilla lug nuts on every single vehicle I own because I get them through my work. Remember, the the length of the stud or the length of "pinky" finger nail is about how far a lug nut needs to be on the stud.

Post a picture to show us what you are dealing with and hopefully we can figure what what is exactly causing your issue.

 

Oh, and according to my work, the torque is 110 foot pounds.

 

You answered your own question.

 

I have always thought that mine were too short. I hate tightening the lugs sometimes. Im scared they will strip the few threads that are holding on. I think I'm going to get longer ones too. I run steel wheels now so not as bad as it was when I had alum. wheels.

 

You want 1 1/2 times the diameter of threads engaged on steel fasteners. So for a 1/2" diameter wheel stud you need 3/4" of usable thread for the lug nut to engage.

 

btw you using any spacers? aluminum or steel wheels?

aluminum wheels NEED that longer engagement because the different heat cycles of aluminum and steel loosen them up quick.

 

explains why. Mickey thompson classic 2s i had on my 89 wheel fell off. American racing on the 96 wheel fell off.

Both aluminum. Looks like anyone with alloys should upgrade their studs. I'm posting pics of this Chrystler BS of these chode length studs

 

A few quick questions before a statement.

Are the studs breaking? Are all the nuts but one loosening and then a stud is breaking?

Because if the nuts are all loosening to the point that the wheel falls off and you're too busy to noticed that something is going Clank-kabang-clank-kabang as they loosen, you should probably leave your license on top of the truck and walk wherever you're going from this point forward.
