When driving at a speed above mid-speed, a vehicle with a strong steering wheel may experience periodic abnormal sounds in the chassis. This may be due to the fact that the balance of the directional gear is destroyed and the drive shaft and its spline shaft and splined sleeve may be excessively worn.
The feeling of heavy and laborious turning may be that the rolling bearings in various parts of the steering system are over-tightened, the bearings are not well lubricated, and the heads of the steering rods are too tight or lack of oil. In addition, insufficient front tire pressure can also cause this to happen.
The steering wheel is difficult to handle. During driving or braking, the direction of the vehicle is automatically biased toward the side of the road. This may be caused by the inconsistent specifications of the front wheels or the air pressure on both sides; the front wheel inclination angles on both sides are not equal, and the front wheel bearing clearance Inconsistent or too different wheelbase may also cause this situation.
There is a sense of drift in the vehicle, which is often caused by the swinging front wheels during driving. When the vehicle reaches a certain high speed, the steering wheel may tremble or swing. Even if the sense of direction of the vehicle is not consistent with the expected control, the speed of the car should be reduced accordingly. However, it may also be caused by shimming tires or tire repairs that cause damage to the front wheel assembly dynamic balance, shock absorber failure, loosening of steering system components, and improper front wheel alignment.
