My wife has a 2004 Jeep Wrangler Unlimited which she wrecked this year. She rear ended a full size pick up on ice covered roadways at about 30mph while 4X4 was engaged. The full size trucks rear bumped road up over her bumper impacting the front grill. My neighbor and I completed most all repairs to enclude installing a new Rubicon 3 1/2 lift kit, new Mickey Thompson tires etc. The selector lever in the cab will not move into the 4X4 position. It's like it's hitting something? Could something have been bent upon impact? Visual inspection from underneath does not disclose any issues. Looking for some trouble shooting ideas. Thanks
