The document discusses potential reasons for a BMW car shaking during acceleration, indicating that it often signals an underlying issue requiring professional attention. Problems may stem from damaged CV joints, loose lug nuts, unbalanced driveshaft, tire imbalances, or faulty wheel bearings. Such vibrations can exacerbate with increased speed, highlighting the importance of addressing these mechanical concerns promptly.

2. Your BMW accelerates when the rear
wheels exert a force against the ground
in a horizontal direction.

3. And if your BMW car shakes while
accelerating, there could be many
reasons for it to occur.

4. Mostly, a vibrating BMW indicates that
a problem has occurred and you need
to take it to a professional.

6. There can be an issue with the CV joint,
it can be damaged and causing
vibrations while driving the BMW.

7. When the inner joint gets damaged,
you can observe that the car starts
vibrating under hard acceleration.

8. When lug nuts are loosened, the
wheels will become shaky and while
driving it will seem like the BMW is
vibrating.

9. If the nuts are not checked &
tightened, the nuts could ultimately
loosen out, and your wheel could fall
off while driving.

10. A secondary purpose of motor mounts
is to reduce engine vibrations.

11. They are made up of a hard rubber
which allows them to absorb the
shaking.

12. If your BMW has rear-wheel drive,
power from the engine to the rear axle
and connected wheels is delivered
through the driveshaft.

13. If the driveshaft is even slightly bent, it
will cause the car to vibrate when
accelerating at low speed.

14. When a tire rotates, any weight
imbalance will turn into a tiny
vibration.

15. At much higher speeds, the vibrations
will be more observable, and your
steering wheel will shake.

16. Even the brake caliper can be
responsible for causing stickiness to
the wheel.

17. The shaking will get worse when you
accelerate at high speeds continuously.

18. The treads on your tire are the most
vulnerable areas in your car and they
can get affected easily.

19. Your car will experience a lot of
vibrations which will get more intense
when you accelerate faster.

20. Wheel bearings work to stop your tires
from friction and make them greasy to
stop the vehicle from generating heat.

21. When these bearings become
unbalanced, your BMW car experiences
vibrations.
