This is only an option if you have the CAD, though.

If you have a late 02 like mine, then no soup for us-- no 2wd lo

 

I believe someone is looking into the transfer case for this control. A lot of off roaders will put an another stick in the transfer case to lock the front or the rear individually the offroad brains may know a source, or check with Advance Adaptor for a start. ED

 

I'd sooner just go to a manual hub conversion like Dynatrac or EMS to get 2wd lo.

 

Dyna Trac has a one piece axle to replace the two piece axle and eliminate the cad all together. Just remove the two piece axle and cad system and replace with one axle shaft. Will work with factory spindles and unit bearings. Cost is about $499.00.
