I had to replace the lug nuts and wheel studs on my front tire due to me not tightening the lugs enough and hitting a gnarly pot hole. crap. Bought the studs directly from mopar as i didnt want to have any warranty issues, even if it wasnt a deal breaker, i wanted to play it safe. The guy i got the wheels/tires/lug nuts off of mentioned that he got them from discount tire (in ohio ~150 miles away). They aren't OEM because the acorn cap wouldnt fit right with the center cap installed.
I emailed their rep on a jeep forum and asked if i could buy them individually and what the cost per and shipping would be. this was his response:
Thank you for the PM.
We do have 1/2" open end lugs available individually. The cost per lug is $1.75 plus freight but I would be happy to send you 5 lugs at no charge. Reply back with your full name, address, email, and phone number and I'll have them sent out asap for you.
i know its only like $10 plus shipping, but I thought that was pretty friggin rad.
