1. The steering wheel shakes when driving at high speed
Many car enthusiasts will think that the vehicle is bumpy just because the vehicle speed is too fast. In fact, it may be caused by the vehicle's transmission system. You should check whether the positioning angles of the front wheels meet the requirements, and adjust them if they are inaccurate.
2. When braking at high speed, the steering wheel suddenly vibrates.
This may be due to excessive braking force and frequency, which may cause the brake disc and brake pads to overheat and deform when cold, causing the steering wheel to vibrate. Solution: Generally, the symptoms can be resolved after replacing the brake disc and brake pads.
3. Aging of the rubber sleeve of the transmission device
The rubber sleeves on steering gears, engine feet, etc. have aged and cannot meet the requirements for shock absorption. The main function of the rubber sleeves is to absorb the vibrations caused by the operation of mechanical parts. If there is a problem, these vibrations will be directly transmitted to the steering wheel and cab. .
Of course, if the fasteners of the transmission device are loose, it may also cause such problems. Or the vehicle has been in a collision accident, causing the steering rod to bend and deform, causing the toe to increase or decrease, etc.
4. The steering wheel is difficult to operate
While driving or braking, the vehicle automatically veers to the side of the road. To ensure straight driving, the steering wheel must be held firmly.
The reasons for vehicle deviation include: the front wheel specifications or air pressure on both sides are inconsistent, the front wheel caster angles or wheel camber angles on both sides are not equal, and the front wheel and bearing clearances on both sides are inconsistent.
