I've seen varying responses in searching for an answer about this- With the 4x4 in the Pathy with the selector having 2wd, auto, 4hi, 4lo, can I replace the sealed unit(hub, bearing) with a manual locking hub without any problem with regards to the transfer case or any related parts? Some other sites had posts saying the 4wd in some models had a lubrication pump in the transfer case and that going to manual hubs was not possible. But I'm not sure if they were referring to my model. By the way mine is the 3.5L if that makes any difference
