first time jeep owner (08 wrangler unlimited) and self taught youtube mechanic so please forgive my ignorance. im having some trouble getting my studs to pull through on the rear hub. i triple checked the size they are indeed 1/2" 20s. but for some reason they absolutely will NOT thread in all the way. the brand is dorman and im wondering if maybe the threads are a tad too big on the studs? just curious if anyones ever come across this issue or maybe there is another brand that would work better. ANY ADVICE is appreciated. thanks a lot guys!
