I have a crazy vibration in my car for anything over like 80 mph. I thought it was alignment got that checked, and that is all good (or so I was told, I didn't get a print out), got wheels balanced and the front were chopped on the insides so I put those on the rear and put the ones from the rear up front, the vibration stopped for about 2 weeks now it's back. I was going to write the tires off since these tires suck, but thinking about it more its not the tires because if it were they would do it on the rear too, but those tires were fine until they were put up front.
My brother who used o work as a tech for ford said that could also be cause by lack of suspension travel, but my suspension is still the OEM suspension.
Anyone else have this issue?
Any ideas on a fix?
The car has warranty but I'd rather do things myself, and I something needs to be replaced it would be the perfect time to upgrade it!!!

 

Does it go away above and below 80 or does it get worse above 80?

 

I get a small vibration when I get up near 70. Everything was fine for me until I did my first tire rotation about 5K miles ago. After that it started pulling to the right a bit, but not always. It tracked straight most of the time so I never bothered with an alignment. Most of that has gone away but now up near 70 I'm starting to get a vibration the past few weeks. I'm figuring it's just a wheel balance but haven't done that yet. Hopefully that will fix it and will update when I get it done. 14K miles on the car now.

 

I have been noticing a vibration at that speed too. It's more pronounced the faster you go too. I notice it more when I have the steering in Sport. In Comfort not so much.

 

Is the vibration felt in the steering wheel, or in the chassis?

If it's in the steering wheel, it's a front end issue. Check these things (not necessarily in this order):

0) Front LCA
1) steering rack
2) Tie rods
3) Struts
4) Wheel balance

If it's in the chassis, it's most likely behind the transmission. Check these things (not necessarily in this order):

0) Driveshaft
1) Wheel balance
3) Rear lower control arms
4) Upper control arm

If you recently changed to aftermarket wheels, and THEN you noticed the vibration, try removing the wheels (yes, all four), and look at the brake rotors, you'll find a spring-steel "nut" on one of the studs. These are installed at the factory to keep the rotors on the spindle during assembly. Remove this nut, and put your wheels back on. Some aftermarket wheels do not allow for these keeper nuts and will not allow the wheel to completely seat onto the rotor hat, causing a vibration. Even if you DIDN"T recently nuy aftermarket wheels, you should probably pull these keepers off anyway.

If your car is still under warranty, take it to the dealer and have them fix it.

 

Could also check the lug torque.

 

Hi guys,

I recommend you bring your vehicles in to your dealer to have them checked out. Then PM me with your dealer, mileage, VIN, full name, and best daytime number so I can escalate this to the customer service manager for your area.

Hit any potholes lately? I put a flat spot in a wheel on my last car going over railroad tracks and it was a nasty vibration at highway speeds

 

I'm getting this too on my DD Mazda 6. It happened after I recently got two new front tires. Brought the car back to Mavis and they said it was a balancing issue which they took care of. However, I still have the same problem and have to bring it back again. It's been a good reason to drive the Mustang more though!

 

Could be too that the shop didn't do a road force balance to balance it beyond the normal balance speeds.

 

Wowzer. A lot of suggestions and none of them are the obvious answer. Steering wheel vibration that gets worse as speed increases it's only one thing. A bent rim. Period. Since it gets bad at 80 and not at 65 or so I'd say its minor and repairable.

 

Road balance is designed to determine which wheel should go on which corner. It is typically used when there is still pull after the alignment is in spec. Not for vibrations.

 

Tha faster you go the worse it gets
My steering is in normal mode, I haven't tried the other modes
That's the thing it seems like it vibrates the whole car, but it is definitely in the steering system.
Lug torque is set to 100 ft/lbs.
I don't usually take my cars to the dealer, from my previous experience once it hits the shop once, it seems to want to go back again, and again, and again...
No, no pothole, or anything else like that, I slow WAY down over anything bumpy!!
That wouldn't explain why it got better after the rotation for a while, and is now back.
The wheels look straight when put on a balance machine!!
And again, bent wheel would do it at all times, and wouldn't have stopped after the rotation, then come back.

 

Yes it would. A balance will temporarily make it feel better. But it will eventually start to vibrate again. You could have a very minor bend that you wouldn't see on a balance machine unless looking for it.

 

This right here tells me you don't know much about tires/wheels....

 

Says the guy who constantly gets owned with ridiculously inaccurate statements and opinions.

Ill bet money that its a bent rim.

 

Is that so? So as you state. The ONLY thing that will shake a steering wheel is a bent rim???

 

He said vibrate. And it would by far be the most plausible.

 

A bent rim pretty much makes the tire out of round no?

 

There is one thing all this doesn't address, the front wheels got chopped on the inside, within 2 weeks, bent wheel wouldn't do that (I had one on my daily driver)!
