What is the reason for the sudden weight of the Mondeo s winning steering wheel?

Steering wheel. The reasons for the sinking are: 1. Insufficient booster oil, 2. Tire pressure.

Too low, 3, the bearing fit is too tight, 4, the booster problem, 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.

A rolling bearing is 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 booster system, or rule out whether there is oil leakage inlet seal damage.

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. Hope!

If the steering wheel becomes heavier, it may be that there may be a problem with your power steering system, including the steering axle and steering lever, which also need to be checked.

Hello, in this case, it is recommended to first check whether the tire pressure is normal. The second possibility is a malfunction of the power steering system.

This is the need to check the tire pressure. Check if the booster oil is missing? Your car has now traveled tens of thousands of kilometers?

The steering wheel is too heavy, which may be caused by a lack of air in the front wheel, or it may be caused by a problem with the steering wheel power assist system and needs to be checked.

Mondeo ( Check price |The steering wheel may need to be replaced when the steering wheel becomes heavier. Power steering oil is a medium oil filled into the power steering system, which plays the role of transmitting steering force and buffering. The time frequency of power steering oil replacement is best to be completely replaced once every 1 year or 20,000 kilometers, and Liang Xingdu's daily inspection should be carried out every six months, that is, every small maintenance day should be checked for the power oil.

If the tire pressure is too low, the friction surface between the tire and the ground will increase, and the Mondeo steering wheel will gradually become heavier. Nowadays, many tires are not filled with air. For these cars with finch tires, the tire rubber pressure requirements are more stringent.

Air-filled tires are related to the changing seasons. And tire pressure is closely related to the performance of the car, such as comfort and carrying capacity, and can also affect the life of the tire. So we have to get into the habit of checking the tire pressure.

In addition, if the matching between each bearing between the direction steering is too tight or too loose, it will lead to the smooth and poor smoothness of the bearing, and the phenomenon of sluggishness and heavier steering wheel, then you need to go to the auto repair shop to check the corresponding machine parts.

The cause of "carbon deposition" should not be underestimated, which will cause insufficient combustion of gasoline and cause the engine to shake. The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless. The second is to increase fuel consumption and increase your financial burden.

The third is the difficulty of cold start, that is, the difficulty of ignition, it is not easy to get on the car, and finally the carbon deposition in the combustion chamber will also cause cylinder detonation, and the acceleration at low speed will cause damage to the piston and crankshaft, causing high temperature of the engine and seriously affecting the safety of the car. Then the discharge exceeds the standard, which not only fails to pass the annual review and cheating liquid testing, but also directly aggravates the harm of environmental pollution.

There is another reason: the throttle valve is faulty. Both of these problems can cause engine shake and unstable speed.

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, it means that the steering gear is not faulty. After the above methods of inspection, if the tire, front leaf spring, cluster stove frame, steering gear are not faulty, it can be basically determined.

The reason for the heavy direction is that there are many wanton congratulations:

1: The booster pump is damaged, or there is a lack of oil to assist in fracturing, 2: The gap of the front suspension system is too large, and the lower arm can be replaced after inspection.

3: Turn to the ball head loose mine, and change it after the inspection.

4: Measure the forward speed (i.e. the direction of the steering angle).

5: Check whether the direction booster is leaking, or whether the booster oil is missing 6: Check whether the tire pressure is too low, or whether the pattern is worn off, if the wear deviation is the front lower arm damage, it can be replaced.

7: The steering machine is worn, and it is also possible to get stuck, [If there is a problem with the car, ask the car master.] Laugh early 4S shop professional technician, 10 minutes to solve. 】

In this case, it is advisable to go to a repair shop to inspect the suspension system, which will occur if the ball joints of the suspension leakage system are corroded early. In addition, in this case, it is also recommended to check the positioning of the body, which will also be caused if the toe value is too small, otherwise it can be adjusted.

Please check the steering machine, or check the tire pressure.

It is recommended to check the steering machine hope to help you.

Hello, it is recommended to go for an overhaul.
