This is the first time I have heard about this option for my 04 rubicon. Unable to switch into 2 wheel drive was the number one thing I didn't like about the ruby. When I joined this site I was thinking of upgrading to the 05/06 for this option. After reading a pile of posts the only thing I will be upgrading is the front drive shaft. This is where I need your help. What is the better unit, Warn or High Lifter? For all I know they are the same part.
