New here to the forum hoping to find some help, I don't have alot of experience with vehicle maintenance but I'm pretty mechanically inclined. I have a 2014 GC SRT with about 77k miles. Service 4wd message started to come up a couple months back on engine start up, it was intermittent though rarely came on. Then it started to always come up and I got the codes pulled at the dealer and they said there was no current codes. I had been researching on what it could be I checked the battery cables they were tight and was gonna change the fluid in transfer case and differentials cause I read that could be possibly a problem so I went out to go to the store to pick the stuff up and when turning the wheel sharp there was a binding / grinding noise so I drove to the dealer and asked them to look at it when they could. They called the next day saying it was transfer case they replaced it under warranty and I've been driving it for a week no problems at all and now today the service 4wd message came up when I started the engine to leave work. I'm gonna by the service manual to figure out what all sensors their is and everything that I can check out but any help would be greatly appreciated!
