This answer was rated:

2004 Chevy Colorado. I am replacing hte front brakes. I have the caliper off and the mount off. I have taken the four bolts from the back of the wheel assembly and the main 35 mm spindle nut. I have removed the one bolt I found for the ABS sensor bracket, but I can't seem to remove the hub?
The only thing that could be holding the hub is rust, considering you have removed all the bolts that hold the unit in place. I can send you step by step instructions if you like.
