2008 jeep liberty was making banging noise while driving took apart the passenger side to get the CV axle out and replace it and the parts that say they are for our jeep are not the same. I can NOT find anywhere with the right part. Can anyone help me and tell me what we are doing wrong? Pics show old part and under the car where it goes and new parts that were shipped to us. Why does ours have such a long rod? Why can't I find the right one... Please help
