I seem to have a vibration around 75-85 mph, seems to be in the back of car , any ideas of what it might be. i had the wheels rebalanced didnt help. thx Ron

 

loose driveshaft or need to balance it

 

could be wheels are out of ballance, bubbles in tires

 

scary avatar pic swiftone, I have a vibration and a deep rumbling under 2,500 rpm in 5th gear, but not sure about 75-85 mph, the roads around here are too bumpy to tell what's from the road and what's from the car anyhow.

 

get an alignment, when my car did a similar thing that was what i needed...dont know what else to tell ya :-/ sorry
