Your BMW accelerates when the rear wheels exert a force against the ground in a horizontal direction.
And if your BMW car shakes while accelerating, there could be many reasons for it to occur.
Mostly, a vibrating BMW indicates that a problem has occurred and you need to take it to a professional.
There can be an issue with the CV joint, it can be damaged and causing vibrations while driving the BMW.
When the inner joint gets damaged, you can observe that the car starts vibrating under hard acceleration.
When lug nuts are loosened, the wheels will become shaky and while driving it will seem like the BMW is vibrating.
If the nuts are not checked & tightened, the nuts could ultimately loosen out, and your wheel could fall off while driving.
A secondary purpose of motor mounts is to reduce engine vibrations.
They are made up of a hard rubber which allows them to absorb the shaking.
If your BMW has rear-wheel drive, power from the engine to the rear axle and connected wheels is delivered through the driveshaft.
If the driveshaft is even slightly bent, it will cause the car to vibrate when accelerating at low speed.
When a tire rotates, any weight imbalance will turn into a tiny vibration.
At much higher speeds, the vibrations will be more observable, and your steering wheel will shake.
Even the brake caliper can be responsible for causing stickiness to the wheel.
The shaking will get worse when you accelerate at high speeds continuously.
The treads on your tire are the most vulnerable areas in your car and they can get affected easily.
Your car will experience a lot of vibrations which will get more intense when you accelerate faster.
Wheel bearings work to stop your tires from friction and make them greasy to stop the vehicle from generating heat.
When these bearings become unbalanced, your BMW car experiences vibrations.
