Just drive your truck until they get the axle in. Not that big of a deal, sucks to deal with but no reason you can’t drive it.They want to replace entire axle and assembly.
I know they cannot sell a car with a warranty and then not honor that warranty. Back order or not - they will be giving me a new truck comparable to drive / and/or paying my car payments. If not - they can buy it back.
They can’t let it sit for months.
Ford corporate said they elevated the request to emergency. So we will see.
