Driveline Vibration at Specific Speed Range (high mileage)
I have a 2005 GT auto w/ 110,000 miles on it. A few days ago I noticed some drive-line vibration between 30 and 55 mph. I can not notice any vibration above or below this range. Also I have manually forced different gears (3rd, 4th, etc) and noticed the same thing in each. I am by no means an expert but I was thinking it is something in the diff/axels/wheel bearings due to what I described. I would appreciate any insight anyone may have.
Thanks in advance,
Scott

There are all sorts of things it could be. I would start by putting in neutral at that speed and see if makes a difference. Checking tires for missing wheel weights.
Is it only onder acceleration or is it under decel also? Nothing leaking from the driveline?

I did notice that my wheel weights were gone from all four of my wheels. I had the the stick on type on the inside of the rim, so I did not notice them missing like perhaps I would have the clip on type. I am not sure when they were removed, but the Ford dealership rotated my tires when I got an oil change a little over a week ago.
Guess I need to go to a shop and see if my wheels are all our of balance now.

So I had all four wheels rebalanced today and still have the vibration. I noticed today that when I turn (esp left) the vibration/hum go away. Thinking wheel bearing. Appreciate any other insight.
**edit ** I jacked the car up and did not feel any play in either front wheel. When I checked the rear wheels I found that on both I can push the wheel directly away and toward myself. Is this type of play normal?
