Hi, I have a 2000 LS 69,000 miles. It recently has been making this rattling noise whenever I drive over 50mph. Here is a video of what im talking about: http://www.youtube.com/watch?v=I1GVXbl6MtQ

Anyone know what the problem may be?

any vibration? sounds like it's a tire defect (big bubble) or wheel issue. cold be the trans/engine mounts but that usually isn't speed dependent. possibly the driveshaft center support bearing dying off?

need more info/symptoms.

Does the frequency of the sound increase when above 50 or does it remain constant at any speed?

Really need to givve as much info as possible on what is going on here. As of now it could be almost anything from a tire defect, improper balance, to a worn out driveshaft bushing. Are you getting any type of vibration at all? Please be as detailed as possible with all that you hear or think is going on so we can try to help narrow down your problem.
