In example. If i pulled on road, threw the lever in two high, the four wheel light would alot of times stay on, but if i made a sharp turn, the front would not bind like it would if the transfer case was actually enguaged. Even if i had manual hub locks engauged, as the front differential should compensate for road speed. Unless you have a front locker. Let us know. If nothing else, a full fluid check is very advised. Front diff, tcase, rear diff, trans, heck, do it all buddy. You can't go wrong. <img src="/forums/images/graemlins/smile.gif" alt="" />
