I have a vibration that starts right at 60 MPH and then smooths out. If I hold her at 60 it gets the rearview mirror shaking pretty bad. Any thoughts, opinions or ideas to what's causing this are greatly appreciated. :headscratch:

Oh definitely balance issue. Definitely. Especially since it smooths out. What happens is:
The unbalanced tire begins vibrating at uneven frequencies. You don't really feel it because road vibration and inconsistencies make the ride bumpy anyways. Well, when you get to 60 mph, those vibrations from the tire resonate.
Resonance is when ANY fluctuating matter begins amplifying due to constructive interference. Example: Swinging
So, your tire's vibrations resonate, which gives you that awful bumpy feeling in the steering column. At higher speeds, the vibration is still there, but no longer reinforces itself and is therefore less noticable- "smooths out".
I hope this helped. 40$ balance them. You'll feel like king of the highway!!

I also read on one of these forums that this problem could be caused by an unbalanced driveshaft...
Several people who have replaced their driveshafts do not have this vibration problem...
I will have my aftermarket wheels and tires re-balanced but have my reservations as to the real cause of this problem...
More???

Hey marks86gt,
It does start to smooth out when I ease the gas past 60. I did it 20x on the highway today going to hockey. She shakes right on the 60 mph mark. I have 6500 miles on the OD and the tires have been rotated 1x … not balanced though. I appreciate all the replies and will go for the tire balance 1st. If it's not the tires … one of those fancy drive shafts may be calling

Drive Shaft
In my case, I have an 07 that had the vibration at 70 mph when I first got it. I took it to the dealer, and got the shop Forman to drive the car while I rode along. He noticed it, and we went back to the shop. A quick check on the computer showed this has been a problem before.
Im sorry I cant write a short story, but he ordered a new rebalanced drive shaft from Ford, and it arrived two days later. Vibes are gone now.
Hope this helps, it may not be your problem. Best of luck. :hihi:

Around Cincinnati potholes sprout like the grass in spring. It may even be a damaged tire. Another item that will make a tire shake is if you have one tire that is better or worse than the others. In other words, if you replaced one tire with a used one that is smaller diameter than the others, the weight will tilt and cause vibration. Had a front wheel drive Taurus that did it. Once I replaced 2 tires, problem went away. Not just because I replaced the ******* size one. Make sense?Hey marks86gt,

At first, I suspected ice or snow in your rims...but then I decided to look at your local weather. You don't have snow there right now so that's definately out...lol.
I did however find a neat site that has a bunch of live web cams of where you live:

Enjoy.
P.S., I had the same problem, but it turned out that I'd thrown a weight. Best have the tires spun again.

LOL, Mine has only seen 40º wet snow at the most. Potholes like marks86gt mentioned are everywhere here. Dawrr, def. going for the tire balance. I have to find a shop where they treat the wheels w/ respect though. I hate those wild dudes w/ an impact gun looking over their shoulder instead of the lugnut!
Man...I used to have a decent set of rims, but the 'pro' tire shop mauled the aluminum pretty badly. I learned the hard way that there are some shops that hire people who have no idea how to R&R a performance tire from a mag. Now, I always ask to see the tire changer to be sure it has the proper nylon guard to protect the rim. I also never leave the car unattended and I make damn sure the guy doing the job knows that I'm watching. If he does a good job, I tip him. If he starts trying to cut corners, I'm in his face.
Yes, I too have had Chevy and BMW wheels f-up by the dealer. I met a salesman at the Ford dealer and he told me about some new fangled wheel balancer they have. He showed me his '05 GT and just had the wheels balanced and front end alignment. I let them do it and not a mark on any wheel :bounce2: The 60 MPH bad vibe is gone too! thx above for the tip, but surer that $hit I whacked another rotten stinking pothole yesterday:cursing:

I had the same exact problem as Warlock. the 70 mph buzz. They ordered a drive shaft yesterday and it should be in today.

gosh, i had that but all i did was remove the stupid rotor retaining clips off the studs, one on each rotor, and POOF, no more wobble.
Sonny,
A likely cause of wheel to go out-of-balance is misalignment, which is usually caused by nailing a pothole hear and there (I live in SE NewEngland too, remember!?!). You should see my wife drive--I swear she aims for the potholes! $%(%&$*(#$!!!
Anyway, if you have your tires balanced and it fixed it, but they're starting to vibrate again, get the alignment checked. It may or may not be noticeable to you, e.g., the car drifts to right or left while driving straight on I-195 (in the middle lane).

Aint that the truth.
Hey Mo,
What's up? I noticed yesterday the car pulled left when putting on the brakes. I think you're right on the alignmnet theory. There's few Mf-ing potholes that are impossible to avoid. I hate the damn Highway/town department. How quick they spread their crap and plow 1/8" of snow, but can't get off their fat a$$es to fix the damn holes w/ at least some cold patch.
I guess if I need my interior greased up, I can go to the only shop I've ever been to for alignments.
PS- Still haven't got my lazy broke A$$ to wash and wax the boat. Splashes the 17th wether it's done or not.:cursing:
With my old 2000 pony, I've put on a lot of miles and I've learned 'thru experience 'that if you can't feel the vibration in the steering wheel, it's gonna be the rear wheels or (far less likely) the drive shaft that's out of balance. The drive shaft typically comes with a counter weight welded on it from the factory, but it's pretty rare to see it come off unless your off-roading :winks.
If you can't feel in the steering wheel, I'd put money on it that it's either a rear tire balance issue, or one or more out-of-round rear tires.
If you 'can' feel it in the steering wheel, then it's either a front wheel balancing issue or loose bearings. I've experienced both and they feel exactly the same. I'd pop a jack under the lower control arms and check the bearing play in each front tire before going the balancing route :bigthumbsup. I've never experienced out-of-balance issues that were related to wheel alignment -- but hey, you never know. Personally, I do my own wheel alignments and have been since I bought the car new. It's so easy and the setup cost in like under $20
cheers
