(Summary description)Dust covers on driveshafts in front-wheel drive vehicles are prone to breakage. If you catch it late, it can be expensive to replace, so if you're in a slightly older car, look out for unusual noises and inspect it carefully. What causes damage to the driveshaft assembly boots? The output of the engine is transmitted from the transmission to the wheels via a rod called the driveshaft. In front-wheel drive and four-wheel drive vehicles, the front wheels are driven, but it is necessary to close the steering system so that the driveshaft cranks sharply. There are rubber boots covering this. These are called driveshaft guards, but as they are made of rubber, they can harden or break, which can then lead to breakage. Late detection can jeopardise the driveshaft itself, which can be expensive. Until then, we want to catch it early. Driveshafts What is a driveshaft? Where is the driveshaft? If you don't know, look under the bumper and investigate the bottom of the tyre. From the centre of the car, you will be able to see an iron bar running towards the centre of the wheel. This is the driveshaft. But perhaps, it is a FF (Front Wheel Drive) sedan or 4WD (Four Wheel Drive) sedan. Front-wheel drive vehicles are common nowadays, but they were rare in the past. The practical application of FWD vehicles seems to be difficult due to the need to drive an axle with a large steering angle when steering the tyres. FR (rear wheel drive vehicles) also have a shaft to drive the differential between the rear wheels to drive the wheels, but this only needs to follow the vertical movement of the suspension, which is not much of an angle Not much If the rear suspension is not of the independent type, such as in a commercial vehicle, it is stored in a box and is not visible from the outside, but this type does not have the function of making the shaft flex on its own. If the rubber of the dust cover is broken, it can only be replaced with a new one. The urgency of repairing it outside is low because the shaft will not break immediately, but it is still better to avoid gravel roads and rainy weather. Of course, the sooner the repair is done, the better. Drive shafts Repairs can be made at drive shaft manufacturers and repair shops. The boot has large diameter cleats at each end, with thin rod shanks between the cleats, which are replaced by removing the rod shanks as the dust boots are in the centre. Thus, despite the simplicity of the part it takes a lot of time. If you can find out in advance that the dust cover is broken, it will not cause the drive shaft to rattle, and the repair will be relatively simple. So check your car when you have time.
