First to make thinks clear... I did not break the spacer itself but two studs that come out of the spacers. But let me tell you the hole story: I was driving down the road with 30-40 mphs and I heard a wired noise coming from my right back wheel when I turned left. It was the first time to hear that noise so I stopped immediately. I checked all the lug nuts of my wheels. All wheels where ok except the right back one. Two of the five lug nuts where super loose.... I tried to tight one lug nut but as I applied some force the lug nut came out with half the stud inside it!!!!! Then I pulled the jeep to my garage to check the hole think out. This happened last Sunday. The jeep is now still in my garage cause I am waiting for my teraflex steel spacers to arrive. Note that the inside of the broken stud was super clean with no dust inside it which means that it was not broken before the incident. Last night I tried to tight the other super loose lug nut ( i curious to see what would happen ) and it broke the same way as the first one. The big difference was that inside this broken stud there was dust which means it was broken a lot of time ago.... My three mistakes I did not check my lug nuts periodically, I did not balance my tires every 3000 miles.... and I bought spacers their origin I was not aware of.... Any help would be appreciated.....

 

Some other aluminum spacers....

 

Wheel spacer..........

 

I may have missed this, but is a brand of wheel spacer mentioned in all of this, other than going with a reputable name like TF...........

 

The spacers where installed by my tire shop so I am not aware of the brand..... But for sure they are not some reputable name..... That's why I am going with TF to be better safe than sorry..... Note that four TF spacers here cost me 300 euros!!!! But I don't care....

 

300 Euros?!!!!! That's like $420 USD! I personally would have went with Spidertrax spacers, but you should be fine with Teraflex. Sorry to hear you had stud failure, it could have been much worse though.

 

No spidertrax here

 

I saw a used spacer where 2 of the studs would just spin in the spacer. Some one had used an impact wrench and thats a big no-no.

 

The problem with the two broken studs sounds like cheap NON-grade 8 bolts and the cheapy ones just failed. Your TF spacers will hold just fine. I you break one of theirs I will be impressed and ask what the hell you were doing. TF=good choice.

 

Thats what I think, thanks.
