Is this a hard job?

 

It's easy. well... It's easy if you have the dust shields off the car.
If they're still on the car, you'll have fun with the front wheels. rears are still easy since you can just remove the hub.

 

I am unsure if they are pressed in, but before you destroy the threads with a gripping tool, as I probably would have done, you might try a trick my friend showed me while removing my exhaust Y-pipe to manifold down pipe connection bolts.

If you thread two nuts down onto the stud, back the first one into the second one, and the tight connection should allow you to back out the stud, if it is threaded into the hub.........

I don't know if the studs are pressed or threaded, hope this helps someone even if it isn't for this project. The reverse method is a great way to thread a stud down and get it tight.

 

I thought you could just hammer them out, which ever one is bad.

 

The wheel studs are pressed in from the back on every car I've ever seen.
(unless they're a stupid euro car that has lug bolts.

 

Did you ever do it I’m trying to mine but the dust shield is in the way

 

This is an 8yr old thread but you will need to remove the dust shield.
