Re: clunk noise??????
It happened to me also. I corrected the problem by not leaving the truck on 4x4 when parked. Correct me if I'm wrong guys but I think this is because the 4x4 switch activates a vaccum which is not operating when the truck is off, so when you start it again, it engages suddenly. Don't worry about it too mutch though, if this is the case, it's no problem. Personnaly I prefer leaving it on 2 wheel for parking and changing for 4By after starting the truck. That way you don't get a strange sound "while" starting the truck. My bit.
