Driving your Subaru Forester that shakes at high speeds on the highway with a cabinet vibration or a moving steering wheel is not only annoying, but it can also be dangerous. Such vibrations are signs of a basic problem with your Forster, which should be solved immediately in order to secure the road and the comfort of driving.

Reasons Why Subaru Forester Shakes At High Speeds & Fixes
The most common causes of Subaru Forester tremor are high tire imbalances, flat tires, tire damage, curved rim, rough tire, and loose nuts. The less common causes are bad axles, worn-out pliers or steering wheels, or improper tire pressure.
1. Wheels Are Unbalanced
The main cause of vibration in the Subaru Forester when driving at high speeds is the uneven wheels, especially if the steering wheel is spinning or vibrating. When only the front wheels do not work, vibration is usually more powerful on the steering wheel. If the rear wheels are unbalanced, vibrations can be felt throughout the car body.
How Are The Forster Wheels Balanced?
The wheels of the Subaru Forester can fit in a special piece called the wheel balancer, which is available at most car workshops. The wheels are tied to a machine and then turned. During rotation, various sensors determine whether the wheels are moving or not. When the imbalance is detected, it is corrected by attaching small weights to the line. These compensate for the evenly distributed weight of the wheel and ensure that the tire runs smoothly.
2. Incorrect Wheel Alignment
Poorly aligned wheels can also cause vibration problems in your Subaru Forester. Wheel alignment is an important and often overlooked aspect of care. Potholes and curbs can easily align your wheels, leading to poor control and overheating of your wheels.
How Is Tire Alignment Done In The Subaru Forester?
Wheel alignment is mainly done using electronic diagnostic tools. Using sensors attached to the Forester wheels, the computer system detects the extent to which actual values deviate from the target values. Target values are fixed values stated by the manufacturer. Estimated values can be compared to a computer and deviations are interpreted and adjusted directly.
3. Damaged Tyres
Wheel damage is one of the most common causes of moving steering or vibration of a car body. Look by looking at all the tires in your Subaru Forester for any cuts, cracks, bumps, and uneven aging. But sometimes tire damage is not easily seen, for example when the belt breaks inside the tire, which may even be on new tires.
4. Damage To The Rims
A curved rim can also cause vibration in your Subaru Forester. Such damage usually occurs when obstacles such as curbs, speed bumps, or deep holes are driven very quickly. This leads to vibration, especially when driving at high speeds. Measuring the wheels will probably not fix the problem, the curved rim should be replaced.
Even if there is no visible damage, the entire rim may have a defect that results in an uneven width. An experienced mechanic can detect when a rim is bent by inserting it into a tire gauge.
5. Wheel Bearing Failure
Paralyzed wheel bearing can be the cause of the Subaru Forester quake. The most common signs of bad tires are the noise of the cabinet when driving straight, the sound of knocking when turning a corner, and the car shaking. The faster you drive, the more the grinding noise increases and the vibration is stronger.
What Causes Bearings To Fail In The Subaru Forester?
Even if you drive your Forester in a straight line, the bearings should absorb high radial power. The whole weight of the car depends on the bearings. When driving, speed creates extra energy. When the curve passes again, axial force occurs. The biggest impact on bearings also occurs on uneven roads or when driving in potholes. Impacts of all kinds are more harmful to bearings than high loads. Therefore, all-wheel bearings end up failing. However, how quickly they fail depends on their driving habits
6. Wheel Nuts Are Loose
Another cause of vibration in your Subaru Forester is obvious and easy to diagnose, the tire nuts may be loose or not properly tightened when changing tires. This reason can be checked and removed with the help of a lug wrench.
Important for all tire changes: The wheel hub and the back of the rim around the center hole should be cleaned, preferably with a wire brush, to remove all impurities safely.
7. Bad Axle
The worn or wrong side of the axis may also cause unwanted vibrations in your Subaru Forester. The axle is a shaft or shaft around the wheels and supports the weight of the vehicle. They are responsible for transferring engine power to the wheels.
8. Suspension Or Steering Components That Have Worn Out
Loosening of fixed parts or control system can cause vibration in your Forester. Very worn ball joints or straps make it difficult to steer your car properly. Other common symptoms include a vibration from the front or steering wheel, a squeaking sound, or a thumping sound from your front suspension especially when you are speeding or turning the car. In the worst cases, your forearm can not only vibrate but also vibrate at high speeds, this phenomenon has been dubbed the “earthquake earthquake”.
9. Inadequate Tire Pressure
Low tire pressure can also cause your Subaru forester shakes at high speeds. Make sure the air pressure on all four tires corresponds to the pressure recommended by the manufacturer. The recommended air pressure is recorded in the driver’s door jam or in the owner’s manual.
10. Tires That Are Over-Inflated
If the tire pressure is too high, the tire only touches the road in the middle of the tread area. As a result, it worries a lot and grows old with inequality. Additionally, excessive tire pressure has negative effects: Long braking distance due to the small contact area with the sidewall and tread strength may cause vibration.
Conclusion
There are many reasons why your Subaru forester shakes at high speeds. If you are looking for a reason, you should always start with the most obvious reason, the wheels do not fit or fit properly.
In any case, it is recommended that ordinary people visit the workshop. A professional mechanic can quickly diagnose vibration problems.
