Don't know if this is the right forum, but in the past year or so, I have broken at least 3 wheel studs. One time one broke when I was "crackin" the lug nuts loose with a breaker bar, the other times they have been randomly breaking.

I have been torgueing them to 145 lbs., cause I thought that was safe. I called Pro Comp and gave the wheel number and asked what torque they recommend with that wheel, and they told me to lightly oil the studs and torque to 110 lbs. Is that to loose or will that be good. I also asked whether I was using the proper lug nuts for that wheel and I am.

Any thoughts or insight would be greatly appreciated as this is rather frustrating and frankly getting expensive @ approx. $14.00 a piece from the dealer.

Whast the owners manual say??? It will tell somewhere in there what the factory torque is. Sounds to me like they are getting over torqued and are streaching which is the cause of the broken lugnuts

 

My '06 manual states 135 lbs. for SRW and 145 lbs. for DRW. It also states not to oil the studs.

Using oil and a lower torque actually puts it close to the required torque. Depending on the oil or anti seize used there can be as much as a 40% increase in actual torque noted on the torque wrench. Oils will give you 10 to 25% and some anti seize compounds can get close to 40%.

Do you have Dodge wheels? You list 18" chrome wheels. Also I would get your torque wrench checked. If you are breaking studs you may have an issue with the wrench.

 

No, they are not Dodge wheels. They are Pro Comp wheels.

As far as my torgue wrench is concerned, I just had recalibrated within the past year, so I don't think it's that. But just to be on the safe side, when I
do it again I'll grab my other torque wrench that I just purchased for a spare.

So would torqueing at 135 compared to 145 make that big of a deal? I know it's 10 lbs., but its not like these small wheels studs.

I'm going to replace my broken studs tommorrow after work and I'll torque them to 135 with NO oil and see what happens.

i torque mine to 145 and have never had a problem. had the combo off at least 6 times in the last year changing tires, rotating, balancing ect...
