Has anyone replaced the power antenna on a 1996 Pathfinder?
A few months ago I bent my power antenna mast. It is not completely broken but the lowest segment does not retract anymore due to a kink at the very base. I have attempted to replace it, but after following the instructions from the service manual:
1. Remove antenna nut and antenna base. 2. Withdraw antenna rod while raising it by operating antenna motor.
I am not able to pull the antenna mast from its housing.
I thought maybe there was a problem with the plastic antenna cord being stuck in the motor, so I took the whole antenna and motor off of the Pathfinder, but after a full disassemble there is nothing wrong with the cord or the motor. I just cannot seem to be able to separate the mast from the housing it slides in and out of. Anyone had this problem??
Please help!! I already have a replacement mast and really don't want to have to go to the dealer to fix something that should be pretty simple!

Cruiser/4Runner 1989-1996 Antenna - REMOVAL & INSTALLATION
antenna mast is the type where you can unscrew the mast from the fender,
simply do so with a pair of pliers. Most damaged antennas are simply
the result of a truck wash or similar mishap, in which the mast is bent.
Disconnect the antenna cable at the radio by pulling it straight
out of the set. Depending on access, this may require loosening the
radio and pulling it out of the dash.
Working under the instrument panel, disengage the cable from its
On some models, it may be necessary to remove the instrument panel
pad to get at the cable.
Outside, unsnap the cap from the antenna base.
Remove the screw(s) and lift off the antenna, pulling the cable
with it, carefully.
When reinstalling, make certain the antenna mount area is clean
and free of rust and dirt. The antenna must make a proper ground contact
through its base to work properly.
Install the screws and route the cable into the cab. Make certain
the cable is retained in the clips, etc.
Connect the cable to the radio; reinstall the radio if it was

Once wound onto the spool, install the antenna nut even if the
antenna is not fully retracted. Test the antenna elevation and
retraction; the mast will eventually retract fully.
If your antenna is of the electric type, mounted into the vehicle's body, then it is more common to replace the MAST only.
This is done by:
- loosen & remove the upper locking ring (between antenna & vehicle body),
- turn radio to ON. This will unwind the antenna & cable fully (if cable has teeth, note direction which cable is facing).
- feed replacement mast cable into cavity (ensure cable is facing same way as when it was removed) until cable stops feeding, and hold in position.
- turn radio power off. Cable should grab & begin to retract. Guide the new mast into position. As cable feeds in, the mast will follow and retract to its closed position.
- secure upper ring
