The wiper started to run slowly, then stopped altogether. Now I found Ford has no replacement - they're on back order? For those that can, if you can remove the assembly, you maybe able to get it working in. You can drill a small hole into the bearing housing and get some oil to the bearing and work it in to free up the bearing. I don't know how long it will work. But I found information online of someone doing that, and it seemed to work for them. If yours is still covered under warranty, don't modify the assembly.
