well I twisted the drive shaft off my 2000 firebird this weekend and replaced it with one that came off a 2000 camaro ss. problem is now I feel a vibration in the car especially when I let off the accelerator. Is it possible I did other damage and what could it be? I have never had this happen before and am just worried about my car. I only have 40,000 on it and it us just a weekend cruiser. thanks for any help I receive.
