rubbing/ grinding in 4x4 when I turn
when I am in 4x4 and I turn there is a grinding/ rubbing noise and sometimes it jerks. Its hard to explain, like something is catching i don't really know. It does not happen in 2wd though. Also I just got new Warn manual lockout hubs a few months ago, maybe that has something to do with it. I have stock tire size also and the hubs are in the lock position. Any help is appreciated, thanks!
