i need help on replacing my front rotors, i can replace the pads but i dont know how to do the rotors. any special tricks or tools i should know about or any help would be appreciated.

its a 99 a4

You'll probably need a big hammer to break it free. Clean the hub thoroughly with a wire brush to insure the new rotor seats square, and put some wheel bearing grease on the bare hub to avoid needing the hammer in the future.

.. wheel bearing, ball joints,

I had that problem at the rear.

hair dryer? lol.

...could this work?

but you knew that

I recently purchased new front and rear pads with rotors.
How much would a shop or someone typically install for someting like that?

and if you don't have the tool to compress the piston back into the caliper you can always just use a big C-clamp<ul><li><a href="http://www.audiworld.com/tech/wheel139.shtml">http://www.audiworld.com/tech/wheel139.shtml</a</li></ul>

I do realize that I dont want to over heat the hub and bearing.. btu one just wants to heat the rotor s it'll slip off. Since the alternative it swing away with a sledge hammer, this seems MUCH gentler... no?
