I have a 99 Frontier that came stock with the auto lock in lock out hubs. While I was putting it back together from a driver side rotor change the little white "clutch pack" that engages the 4wd exploded on me. Question is where can I find a replacement pack or would it be better to switch to manual hubs? Called the dealership with the number on diagram but they said they did not have it. Thanks and I really love the info on these forums. 265,000 miles and still going!
