Why the Wheel Bearing Cause Noise in BMW

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.
