removing the power antenna
yep, you will have to remove the fender liner first, the bracket that holds the antenna on will be under the insulation material that faces your door, on mine there was a flap that was covering the mounting screw on the left side as you face the antenna (under the fender, facing the passenger door). Once the antenna is out you will see the fastner that holds the 'round' cover on, remove it and remove the plastic feed piece that broke off, it is also a good time to add some white grease to the drive gear in the antenna. Of course you will have to remove the nut that holds the antenna on top of the fender, I had a tall socket that slipped over the antenna and fit on the nut.
