AWD fault error service update

22 XLT EB 4K tow

Howdy yall, in another post or comment I mentioned that I had intermittent issues with the AWD system fault popping up. I had these error code on an on/off basis for a while, rear driveshaft speed sensor circuit codes in the AWD module. C05F4, C0F51. Dealership says that it should just be the sensor in the rear diff that needs to be replaced. However I guess sometimes it can be a pain in the ass and will sometimes split upon removal and have to be drilled out of the rear end, so if anybody is having similar issues keep an eye out for that if you're going to self service it.

I also had an issue with what I believed was a coolant leak. Fresh snow on the ground and I spotted some bright green drops in the snow, figured it was leaking coolant. Tech said he had it pressurized for a while and couldn't find a leak, but the system was a few cups low. So I'm either bruning coolant or the tech just can't find the leak. So I guess I gotta keep an eye out for that now too.
