Had no issue til the other day. The 4x4 actuator cable was broke for awhile so wasn't using 4wd for awhile. I fixed it the other day and it went into 4wd and drove good. Then after driving about 10 miles it started making a humming type noise in the back end sounds like passenger side rear.. Originally started at 30 miles and stopped at 40 . No it's starting at 20 and going up to 50 when I go under 15 it makes a grinding noise in the front end. If it cools down and sits over night it doesn't make the noise til it warms up.
