What causes the Volkswagen Lavida to shake when accelerating to 60 mph?
3 Answers
The reasons why the Volkswagen Lavida shakes when accelerating to 60 mph are as follows: Dirty throttle body or excessive carbon buildup in fuel injectors: After driving for a certain mileage, a dirty throttle body can cause it not to close properly or the idle stepper motor to get stuck, both of which can lead to high engine idle speed. Carbon buildup generated during engine operation can also cause vehicle shaking. Solution: When the vehicle experiences shaking, the first step is to inspect the throttle body and fuel injectors. If excessive dirt or carbon buildup is found, they should be cleaned promptly. Worn engine mounts: Vehicle shaking can sometimes be related to aging engine mounts. Engine mounts are essentially the shock absorption system of the engine, responsible for absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can transfer to the steering wheel and the cabin, causing shaking at idle. Solution: If the shaking at idle does not decrease when the vehicle's air conditioning compressor is running, this type of shaking is likely caused by worn engine mounts, and they should be replaced promptly.
My Volkswagen Lavida also had this issue before. When the throttle reaches 60 km/h, there's a slight vibration, most likely caused by wheel imbalance. At this specific speed, if the tires have uneven wear or the rims are irregular, it can create resonance and shaking, making the steering wheel feel wobbly. Check if the tire pressure is consistent—each tire should be maintained near the manufacturer's recommended value. If the tires are deformed or the wheel bearings are loose, the problem could worsen. I recommend getting a four-wheel alignment and dynamic balancing done as soon as possible. This is a common cause, and the repair isn’t too expensive. Don’t delay, as prolonged neglect could damage the suspension system and compromise driving safety.
I used to experience shaking when accelerating to 60 km/h in my old car, probably due to a faulty driveshaft. The driveshaft connects the engine to the wheels, and if the universal joint is worn or deformed, it can easily transmit vibrations at certain speeds. The inspection method is simple: park on level ground and gently push the wheel to check for any looseness; if accompanied by a humming noise, the driveshaft likely needs repair. Don't ignore it, as it could lead to more expensive issues like transmission damage. Pay attention to unusual noises after daily driving and remind the mechanic to check chassis components during maintenance to effectively prevent such shaking—ensuring peace of mind and safety.
