Ok guys this is the third time this has happened. Im running a 99 1500 4x4 lifted 6 inches with 35 inch BFG mud terrains. I was driving at about two in the morning to Austin a couple weeks ago about 75 mph, then all of the sudden my front passenger side broke off the truck. All of the lugs just snapped off at the same time sending sparks flying as the rotor dug into the pavement, luckily no damage to the vehicle except for five sheared studs and a demolished rotor. In about december, i was driving through a field at about 25 mph and the exact same thing happened to the same wheel. I also had the same problem with the front driver side wheel before I installed the lift. I have had the front end aligned several times and I am almost positive that the lugs werenot over tightened because I tightened them by hand with a 12 inch ratchet and i dont think i could overtighten them by hand with only that amount of leverage. I also made sure they were all tight befor I left for Austin. I don't have a clue what is causeing this; anyone ever had this same problem, is there any super heavy duty wheel studs I can buy... this is a pretty dangerous situation so any input would be appreciated.

 

ask this question over on pavementsucks.com, they have seen just about everything when it comes to issues like this.

 

Seems fishy that you'd get an entire batch of bad wheel studs. Are the lug nuts the right type for your wheels? Acorn versus taper seat?

I think ARP makes wheel studs, you might try looking them up on summitracing.com

 

It sounds like something is locking up while the wheel is still trying to turn, try a little physics here, rotor turns on wheel bearing attached to u joint attached to front axle, if something locks in there it will transfer torque to the weakest point, which are the lugs because the size of the tires you are running (alot of surface covered by them), and the sudden lockup its shearing your lugs, I had a Ford F250 did the same thing (think it was wheel bearing and it eventually toasted my spindle) I thought the u joint would fry first but didnt happen that way
Torque is a wicked thing, it may be happening so fast that you dont even feel the initial lockup and it may not stay locked up (heat), anyhow just a hypothesis.
