I am trying to figure out which one they replaced... drivers/passengers ?
I have the other two and was thinking of trying myself due to the 3hrs rate local shop wants for one side - says its very hard to get to.
Any help /suggestions would be appreciated!
Thanks,

If it is a pain for the dealer to replace, it will be a double pain for you unless you know how to do it. Besides getting to it, they can be frozen and almost impossible to take out. They often need a special tool due to the pigtail wires that come out of them. Then you must use high temp anti-seize on the new one, otherwise it will be impossible to remove in the future.
