Front-wheel drivetransmission shaftThe life span of the dust cover simply broke.If it is found late, it needs to be replaced and the price is expensive. Therefore, if you are riding in an older car, please pay attention to the abnormal sound and check it carefully.

What causesDrive shaft assemblyDamaged dust cover?

The output of the engine is calledDrive shaftThe rod is passed from the transmission to the wheels.In front-wheel drive and four-wheel drive vehicles, the front wheels are driven, but it is necessary to close the steering system, so the drive shaft will bend abruptly.There are rubber boots covering this.

These guards are called drive shaft guards, but because they are made of rubber, they may harden or crack, and then cause breakage.Late discovery can endanger the drive shaft itself, which can be expensive.Before that, we hope to find it early.

What is a drive shaft?

Where is the drive shaft?If you don’t know, look under the bumper to investigate the bottom of the tire.From the center of the car, you can see an iron rod extending towards the center of the wheel.This is the drive shaft.But perhaps, it is an FF (front-wheel drive) sedan or a 4WD (four-wheel drive sedan).Nowadays, front-wheel drive vehicles are very common, but in the past they were rare.The actual application of front-wheel drive vehicles seems to be very difficult, due to the need to drive a shaft with a large steering angle when turning the tires.

FR (rear wheel drive vehicle) also has an axle, which is used to drive the differential between the rear wheels to drive the wheels, but this only needs to follow the vertical movement of the suspension, and the angle is not too large. If the rear suspension is not independent For example, a commercial vehicle is stored in a box and cannot be seen from the outside, but this type does not have the function of bending the shaft itself.

If the rubber of the dust cover is damaged, it can only be replaced with a new one.Because the shaft does not break right away, the urgency of repairing outside is very low, but it is still better to avoid gravel roads and rainy weather.Of course, the sooner the repair, the better.

Repairs can be made atDrive shaft manufacturerAnd repair factory.There are splints with larger diameters at both ends of the boots, and there are thin rod handles between the splints. Because the dust cover is in the center, the rods must be removed before replacement.Therefore, despite the simple parts, it takes a lot of time.If the damage of the dust cover can be found in advance, the abnormal noise of the drive shaft will not be caused, and the maintenance is relatively simple.Then check your car at any time.
