Steering wheel jitter - tire wear

In the face of a bumpy road, the steering wheel flickered. This was due to the fact that the car was wearing and the tie rods were loose or loose at the joints, and the tires became irregular due to wear. At this time, professional-to-professional maintenance points should be sent for inspection, and damaged parts should be promptly replaced.

Steering effort - steering shaft bending

There are many reasons for the steering effort. The rolling bearings and sliding bearings in various parts of the steering system are over-tightened; the bearings are not well lubricated; the ball head of the vertical and horizontal tie rods is over-tightened or lacks oil; the steering shaft and the casing are bent and cause jamming; Inadequate adjustment of the front wheel toe; bending of the front axle or frame; insufficient tire pressure, especially front tires.

Do not move the reverse disk - the harness falls off

If the steering wheel does not move, it is very likely that the brake light control harness is disengaged and the wire is wrapped around the direction of the column tube. After the wires were tightly tightened, they couldn't move and at the same time tightened the brake pedal.

The steering wheel floats - the balance of the front wheel is destroyed

Drifting of the steering wheel is often caused by the swinging of the front wheel during driving. The front wheel assembly dynamic balance is damaged due to shimming tires or tire repair, the drive shaft assembly has loose parts, the dynamic balance of the drive shaft assembly is destroyed, and the shock absorber fails. The rigidity of the leaf springs is inconsistent, the wear of the steering system is loose, and the front wheels are improperly aligned.

Steering wheel deviation - different specifications of the front wheels on both sides

Steering wheel deviation is due to the fact that the specifications of the front wheels on both sides, air pressure, caster, camber are not the same, the clearances between the bearings are not the same, the crank springs on both sides are inconsistent, or the wheel brake gap is too small, or the brake drum is missing. Round, causing the side brake to issue a card, causing the brake to drag.

Hand numb - drive balance is destroyed

When the vehicle is traveling at a speed above mid-speed, the chassis is periodically buzzing. In severe cases, the cab and doors tremble, and the steering wheel vibrates strongly until the hand is numbed. This is due to the balance of the steering gear being destroyed, the drive shaft and its splines. Shaft and spline over wear.
