What are the symptoms of tie rod head damage? What needs attention?

During the driving, we must pay attention to the symptoms of the bad Ball joint and tie rod

1. The steering wheel vibrates violently while the vehicle is driving
When the vehicle is driving at a speed above medium speed, the chassis will make periodic noises. In severe cases, the cab and doors will tremble, and the steering wheel will vibrate strongly, even the hand numbs. This is due to the destruction of the dynamic balance of the direction transmission device, the transmission shaft and its splines Caused by excessive wear of the shaft and spline sleeve.

Symptoms of a broken tie rod or ball joint
1. Symptoms of a bad car front wheel ball joint
1) The bumpy road section, chuckles.
2) The car is unstable and swings from side to side.
3) The brakes are off track.
4) Direction lose.
2. The ball joint is too wide, and it is easy to break when subjected to impact load.
3. The outer ball joint is the manual tie rod ball joint, and the inner ball joint is the steering gear tie rod ball joint. The outer ball joint and the inner ball joint are not connected together, they must work together. The ball joint of the steering gear is connected to the Knuckle, and the ball joint of the manual is connected to the Stabilizer Link.
4. The loosening of the ball joint of the directional tie rod will cause the direction to run off, and the steering wheel will shake. In serious cases, the ball joint may fall off and the wheel may fall off instantly.

The principle of steering tie rod ball joint
The working principle of the steering tie rod ball joint, The tie rod with a ball joint housing, the ball joint of the steering spindle is placed in the ball join housing, and the ball joint is hinged with the edge of the shaft hole of the ball joint housing through the ball joint seat at the front end. The ball joint seat is connected to the steering wheel. The roller needle between the spindles is inlaid in the groove of the inner hole of the ball joint seat. The utility model has the characteristics of reducing the wear of the ball joint and improving the tensile strength of the spindle.

Why the steering tie rod will bend
This device is used to connect the front wheel knuckle and steering gear of the car, so that when the steering wheel rotates, the front wheel can swing from side to side. The steering tie rod is divided into a steering straight tie rod and a steering cross tie rod. The steering tie rod is a part of the steering trapezoid of the car, which plays a role in transmitting the steering force.

Early warning of car steering wheel failure
1, The steering wheel vibrates violently while the vehicle is driving
When the vehicle is running at a medium speed or above, there will be periodic noises on the ground. In severe cases, the cab and doors will tremble, the steering wheel will vibrate strongly, and even the hands will be numb. This is due to the destruction of the dynamic balance of the direction transmission device, the transmission shaft and its spline shaft Caused by excessive wear.
2. Heavy and laborious when turning the direction
The rolling bearings and sliding bearings of each part of the steering system are too tightly matched, the bearings are poorly lubricated, the ball ends of the steering tie rods and tie rods are adjusted too tightly or lack oil, the steering shaft and the sleeve are bent, causing jams; front wheel toe adjustment Improper; the front car or frame is bent or deformed; the tire pressure is insufficient, especially the front tires.
3. The steering wheel is difficult to manipulate
When driving or braking, the direction of the vehicle is automatically deflected to the side of the road. In order to ensure straight driving, the steering wheel must be held firmly. The reasons for the deviation of the vehicle are: the specifications or air pressure of the front wheels on both sides are inconsistent, the caster or camber angles of the front wheels on both sides are not equal, and the front wheels and bearings on both sides The gap is inconsistent, the wheelbase difference between the left and right sides is too large, the wheel brake gap is too small or the brake drum is out of round, causing one side of the brake to be issued, causing the brake to drag, and the vehicle loading is uneven.
4. Inaccurate steering wheel positioning
It is caused by the head of the front wheel during driving. When the vehicle reaches a certain high speed, the steering wheel shakes or shimmies are caused by the following reasons: the dynamic balance of the front wheel assembly is damaged by the padding of the tire or the tire repair, and the drive shaft assembly There are loose parts, the dynamic balance of the drive shaft assembly is destroyed, the shock absorber fails, the stiffness of the leaf spring is inconsistent, the steering system parts are worn and loose, and the front wheel alignment is improper.
