Vibrations at high speeds

I get a vibration at speeds over 70mph, then the vibrations stops over 80mph. I have had this problem since I got the vehicle at 19,000 miles. It has been in to Ford numerous times. They have replaced the motor mounts, aligned/realigned, balanced/rotated tires. I got new tires/wheels and still have the problem. The tires have been road forced balanced. I had to get new wheels/tires because the tires were walking on the wheels. The vehicle seems good for a day or so, then back to the same symptoms. Ford says everything is within spec and nothing else can be done except to rebalance the tires.

The tires and wheels are not the only thing that needs to be balanced. But I could be getting ahead of myself. First, I need to know the exact type of vehicle you have, and the drive type (such as front wheel drive, rear wheel drive, four wheel drive, or all wheel drive. Then I may be able to pinpoint your problem.

Does it change at all if the tires were rotated?

Car shakes on front driver side after 70mph


Hey,, The problem may not be relate to the wheels at all. Fro what your telling me it sounds like a broken engine mount. This will cause the problem. Basically the engine mount hols the engine to the vehicle and the rubber in it dampens the vibrations. With the rubber broken you will feel the vibrations on the pedal..

However to mention the can be another reason, This one is very unlikely here seeing as the pedal vibrates but just in case check your Alignment and Cambering.

basically take the vehicle to a mechanic to locate and replace the engine mount , ore than likely is the rear mount or the one closest to the driver. You can do this yourself if you like,

1.) Locate the broken Mount (you will see the rubber in the mount broken)
2.) Use a Car jack (the ones you use the change tires) , and use it to lift the engine up to reduce the pressure on the mount.

3.) remove the broken mount and replace it.

Its just 4 bolts, 2 on the engine 2 on the mount to the car body. You will need to get a torque wrench and a lever (cast iron metal pipe will work fine) to add extra leverage to turn the bolts off.

When vehicle is travelling around 70mph and above a vibration or humming noise starts it would appear from left hand side of dashboard. I have checked the engine bay to see if anything has become detached...


The first thing to check is that the front wheels and tyres are in good condition, and that they have been checked for balance. Any tyre fitting shop can inspect the wheels and tyres for free, and will check and re-balance them for a small fee.

Out of balance wheels will cause resonant vibrations at related speed ranges.

I have a 2.4 vtec with 5spd, when I accelerate I get a serious vibration. I've checked the mounts and replaced the right side axle to no avail.


IF your front end is jacked and your front tires are spinning you should be able to see the vibrations. Use a stethoscope on your motor and tranny to isolate vibrations while running.

In your case id start with wheel balancing first. Have them balanced on the car too (ofcourse). Having it only at a specific speed indicates its a harmonic vibration (vibrations that only occur when something rotating,reaches given speeds)
So yeah, start with cheapest repairs and go from there.

I highly doubt its your mounts unless they arn't sitting or torqued properly. If your confident they were installed perfectly i'd ignore that possibility.

Also, with front end jacked and car not running wiggle your wheels left/right, and up/down to see if any play. Spin them and look at them from the front to see if they wobble.

other causes are, tire with a bad tread, one thats about to separate, this is what caused my car to vibrate
deeper causes can include a bad flywheel,, broken or bad motor mount, and a simple alignment

The speedometer reads 70-80mph while in park but the rpms are around 2000. when put into gear it drops back to 0 mph. is that a cluster problem or a speed sensor?


it is problem with speedo sensor coz if it is problem with cluster then when you putting gear it should not get drop, while shifting gear that sensor getting some vibrations so it shows some deflections . replace sensor and solve your problem, thanks.

I HAVE A 1991 LEXUS 400LS THE REAR DRIVER SIDE WHEELS SHACKS WHEN I DRIVE UNDER THE SPEED OF 25 MPH. WHY?


You have a seperated tire or a loose wheel. A seperated tire happens when the tire's plys seperate from each other, this makes the car bounce or shake at low speeds. High speed vibrations are caused by unbalanced wheels. Vibrations under braking are the rotors.
