Why does my car begin to shake when I go 70 mph or higher?

Question

1995 Honda Passport

Answer 1

sounds like worn CV or Universal joints on the drive train ... see a mechanic and have them replaced

Answer 2

Ugh. Come on now people!

Vibrations at highway speeds are ALWAYS tire related and can usually be cured by having the tires re-balanced. Tires are balanced when first installed but the balance should be re-done every 12-15k miles as the balance will change as the tires wear. The better the tire/wheel balance, the less vibration at highway speeds.

Simple.

Now a bad alignment can also cause a vibration but its not the alignment itself that does this but the uneven wear patterns it inflicts on the tires. Once that uneven wear occurs there isn't much you can do about it though even after having the alignment corrected. Usually, an unevely worn tire will also be rather noisy as well.

Answer 3

Could be:
- Tire balance weight missing
- Worn CV joint
- Improper Wheel alignment
- Worn tie rod end(s)
- worn ball joint(s)
- Worn out strut or shock
Any one of these could cause the vibration. A routine inspection and test drive with a good mechanic should find it.
It will most likely be one thing, not all of the above.

Answer 4

It sounds like you need to get the wheels balanced. One of your wheels probably had one of the little lead weights fall off and, now, when the wheel starts spinning fast enough, it causes the steering wheel to shake and vibrate. This usually becomes noticeable at or above ~50mph, and is particularly noticeable if its one of the front wheels that's out of balance.

Take it to your local mechanic or tire shop and they'll be able to fix it for you. Shouldn't cost that much either.

Answer 5

SLOW DOWN !

There are several reasons, why a car will judder at higher speeds

Tracking may need re-aligning

tires not properly balanced

engine mounts may need replacing

etc.

Take your car to a good garage, for a full security check .

Please, slow down , for your own and others safety

Take care
