3. If at this time you can’t pull the mast out and it 
    seems to be stuck, more than likely the grounding/retaining sleeve has 
    annealed itself to the antenna tube.    What we do is 
    generally remove the power unit from the car and put what ever is left of 
    the old antenna mast that is sticking out of the power unit and clamp it in 
    a vice and very aggressively pull on the power unit and the mast Will come 
    out.     If at this time the old mast comes out proceed with 
    step 4.
        4. Compare the 
    Old Mast with the New Mast, not only do they need to look the same 
    physically but the length of 
    the white teethed cable MUST be the same length.  ( 
    NEVER CUT THE NEW MAST CABLE )....   If the cable is not the same length, 
    then you probably have a broken piece left in your power unit....   If the cable 
    is shorter proceed with step 5....   If Both masts are physically 
    the same along with the white cable length continue with step 6.
        5. There are occasions where the antenna cable breaks off 
    in the power unit and will not allow the replacement mast to be pulled in 
    all the way.   In this event you will have to remove the power antenna 
    assembly from the car and place the power unit on the bench.  
    Then remove the main cover. This 
    will expose the drum.
    
    Now take note of the washer 
    between the cover and drum.
    
    
    With the washer out of the way, 
    grab the drum.  Remove any broken pieces inside it, clean it out and 
    regrease with a white lite grease.  Now reassemble the power unit and 
    proceed with step 6.
    
    
 
    
    
     
        6. Insert the new mast cable into the top of the power 
    antenna tube with the teeth facing the same direction which the old one came 
    out,.. then have someone turn the radio off 
    ( with the key in the on position ),.. as 
    the power unit begins to pull the new mast in, guide the new antenna into 
    the power unit, as it pulls the mast down into the power unit, it may on the 
    first try not pull the mast all the way down, don’t worry, install the outer 
    nut and turn the radio on and off a few times as this will center the new 
    antenna mast. then, "Voila! The mast is installed."
     
       7. If the power unit 
    still clicks and grinds at this point, when the mast reaches its top and 
    bottom travel, more than likely the guide that holds the cable next to the 
    gear is bad.  Contact us and we will show you how to fix this.
