What Causes Body Shaking During Acceleration?

The reasons for body shaking during acceleration are: 1. Ignition system issues: Check the working condition of spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or improper spark plug firing can also cause such symptoms; 2. Unstable oil pressure: If you have already cleaned engine carbon deposits, cleaned the throttle body, replaced gaskets and spark plugs, but still experience body shaking, it is recommended to visit a 4S shop to check whether the fuel supply pressure and intake pressure sensors are normal. Solutions for body shaking include: 1. Promptly inspect or replace tires; 2. Check the vehicle's transmission system for any faults; 3. Examine whether the half-shaft tie rod ball joints are worn or loose, or whether the rubber bushings at the joints have fallen off.

Experiencing body shake during acceleration is something I've encountered several times, most commonly due to unbalanced tires. Uneven tire wear or deformed wheel hubs can cause the car to wobble during acceleration, especially at medium to high speeds. Another issue could be with the half-shafts; if the drivetrain is damaged, it leads to unstable power transmission, resulting in body vibration. I recommend first checking tire pressure and wear condition, then performing a wheel balancing adjustment, which typically costs around a hundred bucks to fix. Don't overlook the suspension system either—worn shock absorbers make the car body more sensitive to vibrations, amplifying the shaking. Long-term neglect might lead to more expensive repairs, so it's safer to get it checked by professionals early on.

Severe body shaking during acceleration may indicate an ignition system malfunction. From my experience, carbon buildup on spark plugs or faulty ignition coils can cause irregular engine operation, leading to persistent body vibrations. Tire issues are also common culprits – imbalance or inconsistent air pressure can amplify the shaking. Regular maintenance of ignition components and tire condition checks can prevent this problem. Simply replacing spark plugs often yields immediate improvement. If the drive shaft is bent, replacing the component becomes necessary to avoid driving risks. I typically prioritize checking these smaller parts first as it's cost-effective and hassle-free.

Speed-up shaking is not a minor issue; I believe it poses significant hidden dangers. When the suspension shock absorbers age, the vehicle's stability decreases, making it prone to losing control during acceleration. Damaged engine mounts can also transmit vibrations, so it's important to regularly check the condition of rubber components. Immediate inspection can prevent major accidents—don't wait until trouble arises to make repairs. Safety outweighs everything.
