"Any thoughts......replacing stud?"

Yes. If it's working, don't replace it.

FWIW - one of the first things I do to any vehicle that I obtain (new or new to me) is remove the lugnuts, clean the studs and put a bit of Never Seize on them. Cheap insurance. Most torque specs are given for clean, lubed threads. So I'm of the opinion that the stated spec ASSUMES the threads are cleaned and lubed. If they're gummed up, I raise the torque setting on the wrench a bit.

I've always hammered or pressed the stud out (put lug nut on and turn it til it's flush with the top of the stud for more area to push on). Clean/lube splined area (male and female), get new stud started with a hammer, and then I place a few washers around the stud and use the nut to pull the new stud into place. Have to get a bit ingenious to figure out how to lock up the hub so you can use the nut/torque to pull the stud in.
