had a buddy come over last night and drive it around while i stood outside and listened and its not coming from the front end it just sounds like it when you sit in the drivers seat - sounds like its coming from the drive shaft or u joints somewhere in the middle of the car - when i put it into 4wd low today it drove fine and didnt make the noise any worse like it did two says ago but still makes the same noise - like a popping sound - my buddy said it sounded like the cv's starting to go out but when i drove it and he stood outside and listened we both agreed its not coming from the front end but turning does seem to affect the intensity of the noise - any ideas?
