The dealer is the one that says its non servicable... for example, I have an 11 journey at work that has a ground pin pushed out of the connector on the abs module. the tab is broken that retains the pin in the connector and instead of purchasing the "repair kit" to replace the connector body, I get an entire harness because the repair kit isnt offered for that peticular connector (rightly so I guess, last thing you need is billy bob butt connecting wires for the abs module).
The dealer is likely the LAST place you would be able to source just the damaged part unless you source it ON the driveshaft
If you were going to get lucky at all it would be aftermarket... anyway its solved.
Sorry for the crappy situation bud, that will teach you to do preventative maintainence to your vehicle eh? lol
