Notice
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.



Important
Use care not to twist and damage the ground straps when tightening the retaining nut.


Install the bolts retaining the antenna bracket to the antenna, if the bracket was removed. Tighten

Why are you changing it? If its because the antenna won't stow you can change the mast in most cases and save some serious $$

How To Replace a Defective Telescopic Antenna

Now this is a simple mod and the OEM assembly with motor is $130+. You'll know you have the problem because the antenna won't fully retract



Parts:
Adjustable wrench
GM OEM Power Antenna Replacement ($13 E Bay).




Make sure the antenna is fully retracted and that the radio is off

Remove the antenna mounting nut located on the base of the mast on the outside of the car. If the mast is bent it may be necessary to cut off the old mast). If you can't all of the plastic cable out as one piece, (sometimes the plastic gets really hard and breaks into pieces then falls down into the motor), you can just pull the motor after you have pulled the mast out and get all of the pieces out. To do that you'll need to take out the outer right turn signal housing.




Turn on the radio and pull out the old mast and serrated cable completely out of the antenna motor. (Note which way the serrations on the cable are facing)

Feed the serrated cable of the new mast into the antenna hole and stop when resistance is felt. (about 12”). Make sure the cable is fed in with the teeth the same way the old cable came out.



Turn the radio off to lower the antenna until the serrated cable catches.. You may have to cycle the antenna a few times until the cable catches the gear mechanism and retracts into the antenna motor.



Replace and tighten the antenna nut into the mast base.



Turn on and make sure that the mast fully extends without binding. Clean the surface of the antenna to remove any adhesive etc.

10 minute job.



If you encounter a stuck mast here’s advice from the mast vendor:

You see the new "Retaining Sleeve" (silver, 2 inches or so, with slots) on the shaft of the new antenna mast, the original one is most likely a little corroded/frozen into the shaft of your antenna No problem : You are in need of what I refer to as the "snap and tap" technique of mast removal

Turn radio on and let cycle to as much extension as is currently possible

Take hold of the thickest metal mast section (closest to fender) with you thumb and forefinger about 2-3 inches above the top of the antenna shaft hole

Push the thickest mast section into the shaft (as much as it will go within that 2-3 inches)

Hold tightly with thumb and forefinger and Snap your Wrist upward.....you will here the mast bottom "tap" the bottom of the frozen in place retaining sleeve (what this is all about) Repeat this over and over again In-Snap-Tap-Repeat Short Firm Bursts of Energy Focusing the energy blow to the point of the tap This will free the retaining sleeve little by little till it comes out completely

 

That's the way I did it. Thanks DeeGee!!!!! David

 

The original thread was; change to. I take it he wants to go from a fixed mast to a power antenna.

 

Ahhhhhhhhhhhhhhhh

RT*Q

Now thats a lot harder. No profile info so we need to know if its coupe, Z06 or FRC.

You'd need a power feed, an auto extend command wire and use the existing antenna cable and ground. Not straight forward.

 

OOPS! Sorry. David
