Was driving my car the other today prity hard, was in second when i heard a bang from the front end, now when driving i'm getting a vibration from front passanger side. shaft feals ok but car has been lowered and heard of shafts popping out. Any ideas? Shaft joins, front diff?? Heard of using longer xr4x4 shafts on lowered cars. Just thought i would ask before getting under it.
