What will hapeen if I don't change the wheel bearings hah ? Will it cause the wheels to kapok ? I wonder if it can be due to my tire width (245/R17/45) .....
Every component has a lifespan but is variable if it is a wear & tear item. As this wheel bearing is a rotatable item which is dependable on the frequency of usage and loading.
If you do not change it, noise from that bearing will get louder and unbearable at critical stage. In terms of mechanical parts, noise equates to vibration and vibration equates to higher dimensional tolerance run out. Wear and Tear will accelerate at exponential rate here on until mechanical fatigue.
When this happens, bearing will seized (u might get a locked wheel if your wheel shaft/axle is strong) but usually the shaft will undergo a torsional shear and breaks if one end is fixed mounted.
And other components along the line will fail as the harmonic vibration is very harmful.
So better change it for a better and smoother ride.
