This just happened to my 94 Accord EX.

The dealer said "$180 and 3 hours of labor, we have to take the caliper off and blah blah."

I went to a tire place and they did it in 30 minutes and charged me $30.

Don't bother doing it yourself, pay the $30-40. You don't need to remove the caliper. There is a hole in the back of the disc that allows you to pop the stud out, that's why it only takes 30 minutes if you know what you are doing.
