My Sylphy steering wheel has become heavier, is there a way to fix it

Check whether the cross-knuckle on the downward direction machine is stuck.

The reasons for the steering wheel sinking are: 1. Insufficient booster oil, 2. Tire pressure is too low, 3. Bearing fit is too tight, 4. Booster problem, which can be dealt with according to the actual situation.

1. Insufficient booster oil.

Generally, the feeling of the weight of the direction is relatively constant, if it suddenly becomes very heavy one day, or slowly becomes heavier, it may be that the steering power oil is dirty, it is similar to the engine oil, and it needs to be replaced. Or if there is less oil leakage, then there is less power, so the steering wheel becomes very heavy. In this case, it is necessary to maintain it in time, or to add and change the steering oil.

2. The tire pressure is too low.

If the tire pressure is too low, the area of contact between the tire and the road surface will increase, the friction will increase, and the steering difficulty will increase, resulting in a heavy steering wheel, which is not conducive to driving safety.

3. The bearing fit is too tight.

For a rolling bearing connected to each steering system, it is also closely matched with the sliding bearing, so it will lead to the lubrication of the bearing can not be well run, which will affect the phenomenon of stagnation, causing the steering wheel to become sinking, this situation should check the mechanical part and the power assist system, or rule out whether there is a leakage of the inlet seal damage phenomenon.

4. Booster problem.

The relationship between the steering wheel and the booster is inseparable, so when the steering wheel becomes very heavy, it is likely that there are some poor circuit contacts or other problems inside the booster system, which should be repaired by the 4th shop.

Is it an oil assistant or an electric assistant.

Nissan Sylphy steering wheel has no pullback: this may be a problem of inclination, need to do a four-wheel alignment, it may be that the steering rod on both sides of the tooth distance difference is too much, one side stretches very long, the other side shrinks very short, the tire is the front speed and camber is not adjusted well, the automatic return is to rely on the kingpin leaning and camber to cooperate, in this case if the steering wheel is on the right, that is to close the right, put the left. If there is no positive force because of the weight of the steering wheel, you need to solve the problem from the direction of the steering wheel, including checking whether there is dirt wrapped under the steering machine; Check whether the oil level of the steering machine is normal, and whether it has not been replaced for too long and deteriorated.

Kiss! I changed the steering oil! Check the front shock absorber flat bearings again.

The first is to see if the belt of the direction booster pump is broken, the second is to see whether there is a lack of oil, and the third is that the direction booster pump is broken.

1. The booster oil is insufficient, and the booster oil is the main driving force to promote the car, so when the booster oil is insufficient, the car is naturally difficult to drive, not to mention the change of direction in the first round. 2. The uncleanliness of the booster oil, if it is difficult to move the steering wheel when the car is steering, it may be that the booster oil is mixed with unclean mixed gas or impurities, which causes the booster oil to be unable to be used normally and pushes the car to drive.

1. Analysis of the reasons why the steering wheel of the car is very heavy:

1. Insufficient booster oil is the main driving force to drive the car**, so when the booster oil is insufficient, it is naturally difficult for the car to drive, let alone turn and change direction.

2. The uncleanliness of the booster oil, if it is difficult to move the steering wheel when the car is steering, it may be that the booster oil is mixed with unclean mixed gas or impurities, which causes the booster oil to be unable to be used normally and pushes the car to drive.

3. If there is a problem with the booster, the relationship between the steering wheel and the booster is naturally inseparable, when the steering wheel becomes heavy, it is very likely that there is a poor circuit contact inside the booster system or other problems.

Second, the car steering wheel is very heavy solution:

1. Replace the booster oil so that the long-term use of the booster oil may lead to the unclean situation of the booster oil, and in the event of this hail situation, the booster oil should be replaced as soon as possible to ensure the normal driving of the car.

2. Check that most of the accessories in the power booster system car rely on electricity to drive the work, so when the steering wheel is not easy to use, you should check whether there is a problem with the booster in time, and drive the car to the repair shop for professional maintenance.

3. Ensure that the front tire pressure is sufficientIf the steering wheel becomes heavy when steering, you can check whether the air pressure of the front wheel is sufficient, if the air pressure is not enough, it should be added in time to ensure the normal driving of the car.

The weight of the Nissan sylphy steering wheel may be the steering system The rolling bearings and sliding bearings of each part are too tightly matched, the bearing is poorly lubricated, the steering tie rod and tie rod ball joint adjustment is too tight or lacks oil, adding some lubricating oil is enough. The all-new Sylphy is basically a continuation of the design of overseas models. The front grille adopts the Nissan family's V-shaped sports front face design, the headlights are connected to the grille, and the LED daytime running lights look sharper.

In addition, the new front bumper also makes the new car look more sporty. Inside, the interior of the new car is more stylish than the old model. The center console is designed with a recessed LCD screen, which simplifies the design of the center console buttons.

In terms of equipment, the new car will be equipped with Apple CarPlay system, lane departure warning system, lane change blind spot warning system, reverse side warning system, multi-function steering wheel, one-button start, dual-zone automatic air adjustment, front seat heating and other configurations. In terms of power, the all-new Sylphy will continue the powertrain of the current model, offering a naturally aspirated engine with a maximum power of 126 hp and an engine maximum power of 139 hp. In terms of transmission, the engine will be mated to either a manual or CVT gearbox.

The steering wheel may be overweight due to the rolling bearings and sliding bearings of various parts of the steering system are too tightly matched, the bearing lubrication is poor, and the ball head of the steering longitudinal tie rod and transverse tie rod is adjusted too tightly or lacks oil, and it is enough to add some lubricating oil.

**The exterior of the Sylphy basically continues the design of the overseas version of the model, the front grille adopts the Nissan family-style V-Motion front face design, the headlight group is connected to the grille, and the LED daytime running stove imitation curve lights look sharper. In addition, the all-new front bumper also gives the new car a sportier look.

In terms of interior, the interior of the new car is more fashionable than the old model, which is designed with an embedded LCD screen in the center console, and simplifies the design of the center console buttons, configuration, the new car will be equipped with Apple carplay system, lane departure warning system, lane change blind spot warning system, reversing side warning system, multi-function steering wheel, one-button start, dual-zone automatic air conditioning, front seat heating and other configurations.

In terms of power, **Sylphy will continue the powertrain of the current model, offering a choice of naturally aspirated engines, of which the engine has a maximum power of 126 hp and the engine has a maximum power of 139 hp. In terms of transmission, the engine will be mated to either a manual or CVT gearbox. (Photo by photo:.)
