Grinding Antenna

[300hoyo]

i recently replaced an antenna for my sisters 2002 rx300. it was easy enough to find and replace but when it retracks or raises, this grinding sound happens. as if the motor dosnt know its done going up or dwn. i think the motor is still trying to move the antenna and if it continues it will destroy it. HELP!!!

Did you take the assembly out, take it apart and remove the broken piece of the old antenna? I have replaced several of them and never had a grinding sound. I have found that it is wise to remove the antenna assembly, take it apart and clean it thoroughly with solvent and re-lube with white grease. It gets VERY dirty and dry in there from age by the time it breaks.
