OT Pacifica brakes?

My son called today and asked me to help him replace the front brake pads on his 05 Chrysler Pacifica all wheel drive. He brought the new pads and we proceeded to change them. The passenger side was wore more than the drivers side, but neither side looked bad enough to need replacing, but we did anyway. When putting it back together, he twisted off one of the lug bolts on the drivers side. How bad of a job is it to replace the stud? Something you can do yourself, or do you need some special tools? I asked him why he thought the pads needed replaced and he said they could hear a grinding sound once in a while. It has about 110,000 miles on it. I said it could be the rear brakes making the noise, so we attempted to take the rear passenger side wheel off. It is stuck on tight!!! The center cast part of the hub is very rusty. I tried taking a BIG hammer and hitting the inside of the wheel rim, but was afraid to hit the aluminum wheel very hard. I tapped between the lug bolts on the outside of the rim and sprayed my home brew of ATF and diesel fuel on it to no avail. It was getting time they had to leave so we just put the lug nuts back on and picked up tools. How do you get the stuck rim off the hub? I didn't want to use the flame wrench on the aluminum wheel, what else can you do to it to get it loose? Thanks, Chris

Maybe loosen the lug nuts a bit then drive the car around the yard and see if it breaks free. You will probably hear it when it lets go.

I've hit the tire with a sledge hammer and have had to hit them several times to get them to let go..aluminum on steel!....I put anti sieze on them when they do that

We used a long 4x4 to knock the wheel loose on dads pickup, to change the flat one morning. Just hit the wheel from the opposite side of the truck with it end ways. With it jacked up we turned the wheel as we hit it.

While not a safe practice, I agree with Johndeere720 about driving it with loose lugs to break it loose. A fellow I know has a 1990-something Stratus and had the same problem with the rims corroded tight. He said he had to get pretty agressive (turning) to break them free. Again, not a safe practice. Find a "closed course" to do this in and consider the inherent dangers involved. I wouldn't back the lugs more than 1/8 turn from contact to do this.

Cat Guy has a good idea. We hit them on the inside so as not to damage the aluminum while rotating the wheel. This usually breaks them loose. Don't put anything on the studs when you reinstall.
