1. Your hands are numb when driving. When the vehicle is traveling at a speed higher than mid-speed, the chassis has periodic sounds. In severe cases, the cab and doors tremble, and the steering wheel vibrates strongly until the hand is numbed. This is due to the fact that the dynamic balance of the steering gear is damaged, the transmission shaft and its splines. Shaft and spline over wear.

Heavy and laborious steering. The reasons are due to the fact that the rolling bearings and sliding bearings in various parts of the steering system are over-tightened, the bearings are not well lubricated, and the ball ends of the steering trailing rods and tie rods are tightened too tightly or lack of oil, and the steering shaft and casing are bent, resulting in jamming; Inadequate adjustment of toe; pre-sprung or frame bending deformation; insufficient tire pressure, especially front tires. 3. The steering wheel is difficult to manipulate. When driving or braking, the direction of the vehicle is automatically biased toward the side of the road. In order to ensure straight-line driving, the steering wheel must be firmly held. The causes of vehicle deviation are: the specifications of the front wheels on both sides or the air pressure are inconsistent, and the front wheels or the camber angles on both sides are not equal, and the front wheels and bearings on both sides are The gap is inconsistent. The steel plate springs on both sides do not have the same degree of camber or elasticity. The wheelbase between the left and right sides has a large difference, the wheel brake gap is too small or the brake drum is out of round, causing the side brake to issue a card, causing the brake to stick and the vehicle to load unevenly. Wait. 4. The direction of hair floating. Often caused by driving the front wheel swing, when the vehicle reaches a certain high speed, there are reasons for the steering wheel to shiver or swing: shimming the tire or tire repair caused the balance of the front wheel assembly is destroyed, the total drive shaft Parts become loose, the dynamic balance of the drive shaft assembly is destroyed, the shock absorber fails, the rigidity of the leaf spring is inconsistent, the wear of the steering system parts is loose, and the front wheels are improperly aligned.
