RE: Wheel Bolt/Hub Removal
This procedure doesn't require removal of the hub. I hope you didn't damage anything by applying the heat from the torch!
If you have disc brakes, then remove thecaliper from the rotor and hang itout of the way with wire or some string. Remove the rotor.For drums, remove just the drum. That should expose the hub with the wheel studs. Use a C-Clamp and push the broken stud out the back of the hub. If you still have some wheel stud left, you can thread one of your lugnuts onto the broken studuntil the end of the stud is even with the end of the lugnut -- this provides more surface area for your C-Clamp to push against. Service manual recommends not using a hammer to push the stud out due to potential damage to the bearing. Once the broken stud is loose, remove the lugnut. You should then be able to remove the broken stud from the back.
For installation of new stud:
1. Insert the new stud from the back of the hub
2. From the front of the hub, put on a few washers, topped by a lugnut.
3. Tighten the lugnut -- this will pull the new stud through the hub against the back of the hub.
4. Tightenuntil the head of the new stud is flush against the back of the hub.
5. Remove the lugnut and washers and reinstall your brakes.
