Coincidentally, are you talking to parts or service about this issue? The only reason I ask is I recently had a strange circumstance completely unrelated to your axel problem.
A rock got kicked up and cracked my windshield. I had it replaced with OEM glass by Safelite who couldn't have been more accommodating. However, immediately after the glass was replaced I got an error, "Service Windshield Wiper Sensor". I called Safelite, who came to my home and said it's likely that the sensor had gone bad after removing it from it's adhesive pad on the glass, which the fastest way to fix was thru the dealer.
I called the dealership service department, scheduled a visit, only to have a service adviser tell me that the only way to get the sensor was on another new windshield. They ship complete, I was told. Mystified I called back Safelite, told them what I was advised and they immediate said it was BS, they even found a part number and said I should call the parts department. So, I did.
Guess what. They had the part in stock, and confirmed that the part was indeed the correct rain sensor, and I could come in to get the part replaced. Called the service department again... and like magic... it got fixed!
My point with all this is there might be some major disconnect going on with Parts vs Service at dealerships. Given the nature of dealership experiences people have had in this forum... it doesn't sound far fetched. Might be worth you while to see if your case isn't something similar.
