I rotate my tires everytime I do an oil change. I check my wheel spacers at that time as well.

 

Good plan! Does double duty.

 

Are you guys that run spacers using extended lug bolts?

 

I believe you are thinking the old style spacer. The new style/better spacer are more of a adapter. Put spacer on stock studs and have new studs offset for the wheel.

 

I understand, you are correct, I was thinking of the old style.

 

Not to be negative, but it sounds to me as though someone may have loosened the lug nuts either as a get even or trying to steal them.
The sheered studs happened when the last loose lug nut fell off.

Here is my story......
Many years ago I left a friends home around midnight and discovered later that someone tried to remove my rear 14x7 chrome Cragar SS rims. Driving ar 45 mph the rim came off, car dropped to the ground and tire went by me off the side of the road. Checked the other tire and the nuts were loose too!!
Lucky I had traction bars so ther was no damage to the brakes.
My brother came by with a floor jack and spare tires.

 

Good thing you are ok. That could have been a very bad situation.

 

Same experience as Charles above. Back in the early '70s I was at the movies with the girlfriend. Came out of the show about 2 hours later, jumped in my 340 Duster and headed home. Got about half a mile down the road and Bang! the left rear drops down as the tire and wheel go past my window. Some scumbag had loosened the lugs on both rear wheels, but couldn't get the locking lugs off. Makes for a real thrill ride for a couple of seconds. Got the hook from an FC Jeep wrecker!

 

From reading this post I can say the lugs came loose, this is common when wheels aren't torqued to spec or when there not torqued in a star pattern. How many miles does your jeep have? Also do you have aftermarket lugs on your jeep? I ask about mileage because Chryslers lug nuts absolutely suck! They are a 2pc design and usually the outer portion of the lug nut will swell and can spin causing the nut to not be torqued properly. Also if you have aftermarket lug nuts "tuner lugs" they could of been your problem as well. These are designed for aftermarket wheels but they are just terrible lug nuts period. A lot of people buy them thinking they are " locking lugs" but are mistaken, they are all splined the same and do nothing for security. I see a lot of issues with these lug nuts on stock wheels, most common being coming loose from normal driving.

 

What's the proper torque? 90 ???
