Help!! I have a 2000 Mountaineer 5 0 AWD that needs some assistance. Motor has 60k on it and tranny has around 20k on the rebuild. Last year it developed a constant knocking when rolling. I changed both front CV's and the knocking didn't go away. I then changed the bearing on the front driveshaft and it went away. Now it's making a loud clicking noise from the front end but only after it gets warmed up. It's okay in town for short distances but not for a long haul of any sorts. Any ideas?
