1. Tire balance: Unbalanced tires can cause a vehicle to shake at certain speeds. Have your tires inspected and balanced if necessary.
2. Wheel alignment: Misaligned wheels can also cause a shaking sensation. Have your wheels aligned if necessary.
3. Driveline issues: A worn-out or damaged driveshaft or other driveline components can cause vibrations. Inspect the driveshaft and other driveline components for signs of wear or damage.
4. Suspension issues: Worn out or damaged suspension components, such as shocks, struts, or control arms, can also cause a shaking sensation. Inspect the suspension components for signs of wear or damage.
5. Engine issues: A misfiring engine can also cause a shaking sensation. Have your engine inspected for misfires if you are experiencing shaking at 70mph.
If you are unable to identify the source of the shaking yourself, it is recommended to have your vehicle inspected by a qualified mechanic.
