Buzzing"

Q: My car is always buzzing when it runs recently. What's the matter?

A: It may be caused by serious wear of bearings. So, do automobile hub bearings need to be lubricated? The bearings of family cars are divided into one-piece bearings and light bearings, which should be treated differently.

Bearing Classification of Household Cars

1-in-one bearing

The assembly contains ABS wheel speed sensor and tyre fixed bolts. If there is a fault, the bearing assembly needs to be replaced, and the bearing can not be replaced separately.

2 light bearing

If the bearing wears and breaks down, it can be replaced separately.

Bearing wear failure

Vehicle bearings have worn out, and there will be a "buzzing" sound when driving. It feels like flying, especially when the vehicle is between 60 yards and 80 yards, the noise is the loudest.

Do you need butter regularly?

Household cars have relatively low load and do not need regular butter beating. Butter fluidity is poor, not suitable for car chassis parts, car chassis does not install butter nozzle, but regular maintenance and inspection of the chassis is necessary.

Bearing Maintenance

Lubricating oil should be added after the loss of bearing oil. The amount of lubricating oil needed for axle bearing is very small, as long as the bearing rolling space can be smeared. Too much lubricant will only pollute the hub, or even the brake disc, leading to brake failure.
