go get the replacement mast, Pepboys sell for toyota camry which not much different from es300 (around $25 and MUST be for toyota). Unscrew the nut that holding the mass on the outside, then turn on the radio it should push the mast out and just help pulling it. To install a new one just turn OFF the radio and put the plastic mast back to the antenna, screw it back then you are done.

I read your info about the antenna replacement but Pep Boys said they only sell the fixed mast. What is everyone talking about if this is all they sell? Do you have a part number for the Toyota replacement mast? Pep Boys in Raleigh says they have never had this item and in their book it show n/a under power antenna.
Please let me know.
Also, other instructions have said you must remove a nut from the bottom of the antenna housing inside the trunk. Do you know if there is anything else that you do to replace the mast....It seems there are many people saying many different methods for doing this.
