Why is the car shaking?
2 Answers
The reasons for car shaking are: 1. Poor quality of car fuel; 2. Carbon deposits in the engine valves and intake pipes; 3. Poor lubrication or damage to the spark plugs; 4. Insufficient engine power; 5. Aging of rubber parts inside the engine mounts and transmission mounts; 6. Aging or leakage of high-voltage wires. Solutions for car shaking: 1. Choose gasoline with guaranteed quality; 2. Clean engine carbon deposits; 3. Apply lubricant to the spark plugs; 4. Check the aging condition of parts or mount rubbers; 5. Inspect the working condition of high-voltage wires and ignition coils; 6. Check if there are any faults in the circuit.
I've been driving for nearly thirty years and seen plenty of car shaking issues. The most common cause is tire problems: either incorrect dynamic balance – when the lead weights on the wheels fall off or the balancing is uneven, causing wobbling at high speeds; or low tire pressure or deformed rims – like when they bend after hitting potholes. Engine issues shouldn't be overlooked either: aging spark plugs or faulty ignition coils leading to incomplete combustion in one cylinder, causing noticeable vibrations at idle; carbon buildup clogging the throttle body is even more troublesome. Brake system problems also cause shaking, like uneven brake disc surfaces that make the car jolt when braking. Worn suspension systems are worse – leaking shock absorbers or loose springs make the car sway constantly over speed bumps. Worn universal joints in the driveshaft show up during acceleration. I think regular maintenance is crucial: check tire pressure monthly to ensure consistency; clean carbon deposits during oil changes; don't delay when hearing strange noises – head straight to the repair shop, because safety comes first, and shaking amplifies danger, especially during high-speed driving.
