Pickup trucks are sometimes light and sometimes heavy. When it s heavy, there is a squeak in the dir

Check to see if there is a lack of booster oil.

1) Cause of failure:

1) The inside of the oil cup is too dirty, the filter screen is blocked, or the oil level of the oil cup is low.

2) There is a lot of air in the power steering system.

3) There is a foreign object in the steering system, which causes the flow control valve of the steering pump to get stuck.

4) The tire pressure is insufficient, the steering column of the pump interferes, the connection is loose, the belt of the pump is loose, slipping or the pump installation position is loose.

5) The bolts of each connection part of the tubing are loose, resulting in the leakage of steering fluid.

6) The piston cylinder of the steering gear is worn too much, the oil seal is poorly sealed, and the control valve is bonded or damaged.

2) Fault diagnosis and troubleshooting

1) Check the steering gear, steering pump control valve, oil cup filter, steering oil, and clean the entire power steering system.

2) If the pump is dirty, be sure to clean the inside and outside of the booster pump and the oil pipe (cotton gauze or other multi-fiber cloth should not be used, clean with a clean brush), and exhaust air to the steering system according to the regulations.

3) Inflate the tires according to the regulations and adjust the performance of the engine.

5) Adjust the tension of the belt and tighten the connecting screws of each part according to the regulations.

6) Check the connection parts of the tubing and tighten the connecting bolts.

7) Replace the oil line, power steering pump, or power steering gear.

The buzzing of the truck direction is mostly caused by the lack of steering oil, and it is also possible to cause abnormal noise caused by the aging of the ball joint of the steering tie rod.

The lack of steering power oil in the steering system leads to insufficient oil in the process of power booster pump, which will lead to the lack of lubrication of internal parts and abnormal noise in the process of steering.

There is also a situation caused by damage to the steering power pump, the inside of the power steering pump is damaged, and there will be abnormal noises when hitting the direction in situ, if you continue to steer, the abnormal sound will become louder and louder, and the steering will become heavier and heavier.

The phenomenon of aging will occur in the process of using the steering tie rod ball joint, if the steering tie rod ball joint is aged, the situation that the steering wheel shakes and sounds will be caused in the process of steering, and the steering tie rod ball joint needs to be replaced in this situation, and the four-wheel alignment is carried out after replacement.

When the abnormal noise is very loud when steering, it may be caused by damage to the steering machine, or it may be caused by the excessive gear clearance of the steering machine, in which case the steering machine needs to be replaced.

Summary. The reasons why the steering wheel is heavy and light on the other side: 1. Check whether the tire pressure is normal.

2. The inclination angle of the chassis suspension is not right, resulting in the steering wheel being heavy and light, you can check the chassis data first to check the correct way to play the steering wheel. 3. Remove the wheel and the ball joint of the steering tie rod, if the situation is not solved, there may be a problem with the steering machine. 4. Do four-wheel alignment detection problems.

Mine is a new car Isuzu Ruimai.

Hydraulically assisted. The reasons for hitting the steering wheel while being heavy and light and concealing are good: 1. Check whether the tire pressure is normal.

2. The inclination angle of the chassis suspension is not right, and the lead of the guide stove causes the steering wheel to be heavy and light, and it is feasible to check the chassis data first to check the correct way to play the steering wheel. 3. Remove the wheel and the ball joint of the steering tie rod, if the situation is not solved, there may be a problem with the steering machine. 4. Do four-wheel alignment detection problems.

The steering wheel is generally connected to the steering shaft through a spline, and its function is to convert the force acting on the edge of the steering wheel into torque and then transmit it to the steering shaft. The steering transmission shaft is used as a connector between the steering gear and the steering shaft, which is conducive to the general spike of the steering gear to compensate for the error generated during the manufacture and installation, so that the steering gear and the steering wheel are more reasonable for the installation of the whole trouser stove car.

Four-wheel alignment was done.

If the tire pressure is also normal, it is a problem with the steering machine.

There is also a car repairer, saying that there are bearings in the pickup truck, saying that it is good to run in for a while.

It's not true.

If it's a completely new car, it's going to be run-in.

That's right. New cars.

That's fine, it's good to run in for a while.

1 All most cars squeak when the steering wheel is completely killed left and right and when moving forward or backward, this situation is normal and there is no need to worry. It is better to turn a little direction when the steering wheel is completely killed, so that the sound is eliminated.

I have driven Zhengzhou Nissan for nearly 4 years, and I have encountered the problem you said, in fact, if you look closely, you will find that there is a welded "screw cap" at both ends of the direction lever, which is to prevent you from playing too far left and right.

For a sedan, it is easy to judge that the gap between the direction cages is too large. Pickups don't have cages, usually the hanging thing (I can't remember the name) has a gap.

Try to change the rubber sleeve in front,The sound for no reason is definitely not right,I drove the ZTE flagship A8 also thought about it in those days,I drove to the service station to check and changed a few rubber sleeves.

First, whether the power assist oil for steering is missing (the power pump itself fails) and second, whether there is a problem with the rod ball joint. (Locate whether the dust-proof rubber sleeve has oil seepage) Third, the steering machine itself is faulty.

Fourth, whether the bolts of the lock shelf are loose.

Don't beat the steering to death, it will be extremely damaging to the steering machine. It is advisable to turn the wheel a little after the direction is killed.

As long as the car is ringing, the new car may be better, and it will ring after a few years.

Summary. The reason for this failure is that there is a problem with the steering machine or the power steering oil is not replaced in time.

The reason for this failure is that there is a problem with the steering machine or the power steering oil is not replaced in time.

The neutral coasting steering will not sound, and the steering will make an abnormal sound when the steering is engaged.

Squeak. Then your reason may not be the reason for the steering wheel, it may be the fault of the transmission shaft, you can check it.

However, the sound was a squeak coming from the steering wheel.

Then go check the booster pump and the drive shaft.

First, the cause of the failure.

The knuckle arm is deformed. Steering knuckle thrust bearings are missing or damaged. The gap between the kingpin and the bushing of the steering knuckle is too small or there is a lack of oil.

Deformation of the front axle or frame causes misalignment of the front wheels. Insufficient tire pressure. The steering gear bearing assembly is too tight.

The meshing clearance of the transmission pair is too small. The ball joint pin of the transverse and straight tie rod is assembled too tightly or the joint is short of oil. The steering shaft or main pipe is bent, rubbing against each other or jamming.

Improper lubrication of the steering gear, improper adjustment of the toe.

2. Fault diagnosis and elimination.

If you feel that the steering wheel is flexible when you prop up the front axle, the front axle and wheels will fail. This is because when the front axle is propped up, the contact resistance between the wheels and the road surface when the steering wheel is turned is no longer there. At this time, you should carefully check whether the front wheel air pressure is too low, whether the front leaf spring is good, whether the frame is deformed, etc.

Prop up the front axle and turn the steering wheel, if you feel heavy steering, it means that the fault is in the steering gear or steering transmission mechanism. At this time, the steering arm can be removed, and then turn the steering wheel, if it feels heavy, it means that the steering gear is faulty inside, and the damaged parts should be repaired or replaced as needed.

After removing the steering arm, turn the steering wheel, if it feels light and flexible, the steering gear is not faulty. After the above method inspection, if the tire, front leaf spring, frame, and steering gear are all faulty, it can be basically determined.
