I noticed that my 2003 Lincoln Aviator vibrates alot over 80MPH?!?

Question

NOW GRANTED....I probably should not be going over 80 with it, but is that normal due to its size and weight or is there something wrong?

Answer 1

You're right. Your car is trying to tell you to slow down and live.

Answer 2

Most likely one of the wheels is out of balance either from throwing a small weight or from not being spin balanced precisely enough, probably a rear or you would feel it more through the steering wheel. I recently have been driving a friend's car that would start vibrating at 65 but not at 62. Went away after tires were rotated and balanced. When I walk, I notice lead tire weights beside the road (and pick them up and melt them), so losing them is fairly common.

Answer 3

Wheels need rebalanced, a few times I had to have this done up to 3 times before the vibration stopped, not all tire shop balancing machines are calibrated properly or if they are the kids balancing your tires don't take the time to do it right. There is also a very small chance you have an out of balance drive-shaft.

Answer 4

So why are you driving over 80 mph?? Unless you live somewhere like montana - THEN it's a different story. But in all reality the car body probably wasn't built to seriously go over 80mph. While it is capable of doing so, it obviously doesn't like to. So there.

Answer 5

Too bad they don't make 'em like they used to. My Windstar SE begins to vibrate at about 85 but then it becomes less noticeable at 90+, and is very smooth at 103

Answer 6

Have your governor checked. A lot of SUVs are governed to about high 80's or low 90's because they can lose control at high speeds because they sit so high.

Answer 7

Maybe it just needs an alignment or balancing of the tires???

Answer 8

is it a vibration or a hop. your wheels are probrably out of balance. check that and your alignment.
if it shimmies when you brake it is your rotors.
