The wheel bearings roll inside the wheels of your BMW in order to minimize the friction. If you listen to sounds coming from the wheels, then it might be due to the inappropriate installation of the bearing. Other factors such as driving on rough roads, unbalanced tires, and drive on deep water also lead to unwanted noises. See the mentioned slides to know about the causes of wheel bearing noise in a BMW.

1. Why the Wheel
Bearing Cause Noise
in BMW

2. The main purpose of
wheel bearing in your
BMW is to allow the
wheels to rotate with
the minimum
frictions.

3. When you stop the
BMW, the bearing
first cools off and a
vacuum is generated
from the lubricant,
air, and the
contrasting metal.

4. The seal of the BMW
hold the vacuum,
otherwise, the sealed
hub or bearing will start
pulling the air from
outside with water and
other contaminants.

5. Generally, the wheel
bearings are attached to
the wheel and constantly
moving. When the
wheels touching the road
while driving, it will
make strange noises.

6. The following points
define the basic
reasons behind the
causes of wheel
bearing noise in a
BMW.

7. Inappropriate
installation

8. If you have recently
replaced the wheel
bearing of your BMW,
then it's an obvious thing
that they are working
very smoothly.

9. When the wheel bearing is
installed improperly or
against the manufacturers
recommendation, then it
will cause strange noises
and somehow damaged.

10. Driving on rough
roads

11. The wheel bearing
generally keeps the entire
pressure of the weight of
the BMW. But when you
drive it over a bumpy
road, it will damage quite
easily.

12. When your BMW hit
something, the bearing
ball will get forced into the
race and the grooved ring
where the bearing sits and
cause more heat and
friction.

13. Unbalanced tires

14. The wheel system of
vehicles completely
depends on its wheel
bearing, lower arm, tire,
lower joint, shock, and
knuckle arm.

15. When the tire is
unbalanced, some of its
parts got damaged and
produce noise from the
wheel bearing.

16. Drive on deep
water

17. Wheel bearing seals are
generally designed by the
engineer that can help the
BMW to leave the
pressure in the wheel
bearings.

18. If you drive it on a street
of flooded water, then
your bearings would be
subjected to moisture,
cause bearing to endure
excess friction and
damage it ultimately.

19. Near the wheel
area

20. Wheel bearing of the
BMW is constantly in
motion and connected
to several other parts of
the car.

21. If the wheel area of the
BMW is subjected to face
an accident, then the
wheel bearing can be
damaged and cause severe
noises.

22. Conclusion

23. With a damaged or
broken wheel bearing, if
you drive your BMW over
a rumble strip on the
shoulder of a highway, it
will cause more noticeable
noises.

24. The wheel bearing noise
will be amplified when
you take the turn and
allow more weight of the
BMW to be transferred to
one side of the car.
