Taking it one modd at a time....
I need some help folks. I have a 05 F150 4x4 STX with the 4.6L and 3.55LS. When driving home last night I turned left and felt this awful jerk and heard a bang like I ran over something. I passed it off for the moment like I did run over something since it was dark. However now whenever I have a turn either direction, but more to the left, that is say turning the actual tire half as far as it will go while driving I get the same felling, sometimes loud, sometimes softer, but I still fill the truck move and jerk. When driving straight the truck is fine. It also did it once from a stop when I went to go forward. Does anyone have any idea what this could be? I was thinking maybe the rear end or LS because of the turning? Or could it be suspension, which I doubt because I've never had anything like that before? Maybe a U joint? I just don't know. I can't really tell where it's coming from because it is so rash. I thought maybe the front 4x4 try to engage, but it does the same thing when I have the 4x4 engaged. Any body have any suggestions?
