So i got a 2004 grand Cherokee limited 4.7HO and heard a funny noise from what sounded like the rear so I changed the wheel bearings(Dana 44) and now even after both sides done I can still hear the noise and just now realized I'm unable to move the jeep if I'm not in active 4wd or 4lo. If i put it in neutral I just sit there. No forward or backward movement. I'm lost in what to do as im new to this keep thing. Thank you to anyone that replies.
