86xj Larado, 2.5l, ax-15, np-207, 186,000mi. In 4hi at about 25mph, get a low pitch harmonic hum that goes away when shift out of 4wd. Suspect the TC front output shaft bearing. I suppose it could be a front drive shaft u-joint or maybe the front differential. Request any sugestions, ideas or smart remarks. If it turns out to be a TC bearing, how tough are these things to take apart?
