ABS pick up sensors

This is my story. Just hope it can help somebody.
Today was ''D'' day. Went to the dealer ford for my gear swap to 4.10. They previously told me it would cost about 200$ plus oil and taxes. Since they will be busy for the next 4 hours, i decided to get breakfeast nearby. My cell phone rang 45 minutes later and the tech told me to get to the garage ASAP.
The mecanic showed me the 2 ABS pick up and they were stock in place. He needs to remove them to continu and to do so, he ll have to break them. I said go ahead, i want thoses gears installed.
Well you know what? thoses things cost 70$ each, 40$ for the wiring an 50$ for labor. If i knew, i would have put some PB blaster on them every day for a week before the installation and i m sure they would have been fine.
Worst part is that the car is stock at the dealer for the entire weekend since they dont have the parts in stock. It SUCKS!!!!!!
There s a good part at this story. Since i m still on warranty until may first , they will replace each bearings involved in the process, including part of the labor for free. I guess they saw how much i was dissapointed.

Also decide that i m trough with mods and trowing money in that car. To bad for my Prochamber.
