I recently purchased a 2003 Rubicon. The bad news is the rear axel is from a 05 wrangler, its still a dana 44 but has no locker. It does have the bypass switch installed. I just wanted know if i will still be able to get the front to lock? The guy i purchased it from has indicated that it does work but i have not tested yet and will do not plan on taking it out of the garage untill i finish eastwooding and then fluid filming the frame and underbody. Any suggestions on what to do if it wont lock in?
