Replaced mine about a month ago and it went smooth.
The "gromments"/clips were the biggest pita.
My local stealership did hook me up...they gave me extras from mechanic stock as damaged mine getting them out.
Cleaned the motor out since it had several broken sections of the plastic teeth in it.
Put all back together.
Turned the radio ON, then OFF.
As the motor was working after turning the radio off, I fed the plastic tail of the mast and whaalaaa! It sucked it rightin. Had to turn the radio on and off again to center itself and job done.
Quick easy job thanks to yotatech!
