[DML] buzzing noise

[delorean502@xxxx]

well, I thought the buzzing at first was in the front. but now i
listened harder and its in the back. when I am driving in 4th at 45MPH
is fine, but if I went into 5th at 45mph it starts to make a high
buzzing sounds. gaining in pitch as my speed increases. i could be
going 70MPH in 4th and no buzzing, but 70MPH in 5th makes that buzzing.
whats wrong with my 5th gear?? thanks for the help
