Over time or if you neglect maintenance, any car will shake and vibrate while driving. However, the car may have some internal problems and you should take them seriously. What parts should you pay attention to if your car shakes when accelerating? Most car enthusiasts will suspect the tires and wheels, but there may be another reason.
The car shakes when accelerating: what are the reasons?
If you are wondering why your car vibrates when accelerating, then you have come to the right place. Problems with the tires can certainly be the cause of shaking. However, the following things are also compelling reasons for car shaking during acceleration:
No. 1. Rear Drive Shaft and U-Joints
One or both may be the source of the problem. If you remove the driveshaft and feel the movement of the joint, any rough areas will be felt and will increase when the engine is running at high power. For driveshafts, a visual inspection will be sufficient. Beware of rust accumulation around the grease seal. Lack of lubrication creates vibration.
№2. Bent Axle
Even a small curvature can cause serious shaking, especially when the car accelerates. Surprisingly, even a small bend in the fenders or a small unevenness in the road can cause the axle to twist. Sometimes the problem can be caused by a worn CV joint, which is located at the end of the axle.
№3. Tires
This is one of the main reasons for car shaking when accelerating. The first thing you should check is if they are securely attached to the wheels. A loose tire not only causes vibration but can also lead to serious accidents.
Unbalanced tires can also be another source of shaking. Unbalanced or misaligned tires, due to tread wear or improper installation, prevent the car from moving straight and level on the road. If one tire is unstable, it can affect the others over time. So, you must fix this problem immediately before it gets worse.
No. 4. Wheels and Steering
If the tires are fine, the next item on the diagnostic list should be the wheels. Loose or damaged wheel bearings can cause your car to shake quite a bit at high speeds. While these parts are unlikely to wear out over time, it is still possible, so keep this in mind. You can find damaged bearings in cars that have been driven for many years without maintenance.
If you feel vibration in the steering wheel, the problem could be caused by a variety of components – struts, bearings, shock absorbers, tie rods, and ball joints.
#5. Seized Brake Caliper
This is not something that happens often, but it can happen. A seized caliper will start shaking at speeds of 60 km/h, and the vibration will intensify with acceleration. When the car vibrates when accelerating, you can smell a burning smell when stopping.
№6. Broken radiator fan
A cracked or damaged fan will not interfere with the engine’s operation in any way, but will cause the car to shake when accelerating. When you start the car, the fan tries to turn, but instead simply swings due to the breakdown. The vibration will shake the car, especially when you increase the speed.
