Is the Corolla steering wheel heavy solution solved?

Hello! It depends on when the Corolla is, if it is the early Corolla, it is the hydraulic steering system with steering machine booster pump. Then you have to check whether the direction of the engine oil is missing, the lack of oil will be heavy, if there is a lack of it, then it depends on whether the power pump works well!

It is possible that the booster pump is seriously worn and there is no pressure, so it sinks! If it's the latest Corolla, that's the direction of the electronic assistant, to put it bluntly, it's through the motor to help the direction, and it's easy to play the direction, this system is also quite complicated, and it needs to be connected through a computer decoder according to the data stream! to judge the damage of the direction machine!

Hope mine is helpful to you, hopefully!

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.

Hello! The steering wheel of the car becomes heavy, and it is possible that the car's four-wheel alignment is inaccurate. It is possible that there is a problem with the caster of the kingpin and the camber of the kingpin. It is recommended to go to a professional repair shop to do a four-wheel alignment. You can also check whether the steering machine is malfunctioning. Hope!

The Corolla steering wheel is heavy, this may be the power steering machine is broken, or the hydraulic pressure inside is blocked or the electric power is broken. It needs to be replaced or repaired.

Hello. The reasons and solutions are as follows: 1. The rolling bearings and sliding bearings of each part of the steering system are too tight before shouting; Workaround:

Repair of rolling bearings in each crack of the steering system. 2. Poor bearing lubrication; Solution: Lubricate the bearing.

3. Turning to the longitudinal tie rod, the ball head of the transverse tie rod is adjusted too tightly or lacks oil. Solution: Readjust the ball joint of the steering tie rod and tie rod.

Check out your friends, I hope it can help you.

The heavy steering wheel of the Corolla can be caused by a lack of power steering oil, a damaged power steering pump, or an oil leak from the vehicle's steering gear. Here's what you need to know about the causes of heavy steering wheels in your Corolla: Damage to the steering power:

The reason why the steering wheel of the Corolla is heavy is that the steering power of the motor vehicle is missing, or the power steering pump of the vehicle is damaged. Oil leakage from the vehicle steering machine: This problem will cause the vehicle to be unable to continue driving, and it needs to be inspected and repaired in time.

What causes the Corolla steering wheel to be heavy? What causes the Corolla steering wheel to be heavy? The heavy steering wheel of the Corolla could be caused by a lack of power steering oil, a damaged power steering pump, or a leak from the vehicle's steering gear.

The following is the relevant knowledge about the causes of the heavy steering wheel of the Corolla: The heavy steering wheel of the Corolla is caused by the lack of steering oil of the motor vehicle or the damage of the front pump of the vehicle swivel.

Oil leakage of vehicle steering machine: After this problem, the vehicle can not continue to drive, and it needs to be checked and repaired in time, otherwise it will affect the safety of the vehicle, and in serious cases, it will cause steering failure. @2019

The Corolla's right front wheel was hit by a low tire pressure, and the steering wheel was heavy

The Corolla steering wheel assist is a power steering ECU that determines the direction and magnitude of auxiliary power based on the vehicle speed signal and the torque sensor signal built into the steering assembly.

The steering torque becomes smaller at low speed and increases moderately at high speed, and the torque sensor stool measures the steering torque generated when the steering wheel rotates, and converts it into an electrical signal and transmits it to the ECU for analysis.

First of all, it is necessary to check whether the tire pressure is too low, and then it is necessary to conduct an on-site inspection and test of the working performance of the power steering system, and the problem of abnormal steering noise may be caused by abnormal wear of the pressure bearing on the top of the shock absorber.

The Corolla is the 10th generation straight-line upgrade of the Toyota Corolla. Since its release in November last year, the Corolla has attracted the attention of consumers around the world; Now, the world's best-selling car has settled in FAW Toyota, once again allowing Chinese consumers to experience Toyota's latest technology and driving experience.

The predecessor of Corolla was AE86!The Corolla's body size has increased significantly compared to the previous generation Corolla, and the whole car has performed unprecedentedly"Wide and low"and create a spacious interior space; The newly developed Twin VVT-I technology for a more powerful power experience in the future. The Corolla is the latest model in its range.

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.

How many kilometers, there are four possibilities, the first tire pressure is insufficient, and the second turf data is incorrect, and you need to do four-wheel alignment. There is a problem with the third-party machine, and fourth, the booster oil has no lubrication or the booster oil is missing

There are 3 possible reasons why the Corolla steering wheel becomes heavier 1. The tire pressure is low, and it is recommended to supplement the air pressure analysis: the air pressure is low, and the friction resistance between the tire and the ground increases 2. The camber angle of the front wheel in the front wheel alignment is close to 0 degrees, and the caster angle of the kingpin is too large

1) The camber angle of the front wheel is close to 0 degrees, the contact area between the tire and the ground increases, and the friction resistance increases; 2) The caster angle of the kingpin increases, the steering resistance increases, but the automatic return ability is also improved; Suggestion: Check the four-wheel alignment 3, the failure analysis of the steering assistance system of the steering machine: 1. The steering wheel power assist is, the power steering ECU, according to the vehicle speed signal and the torque sensor signal built into the steering assembly, to determine the direction and size of the auxiliary power, the steering torque becomes smaller at low speed, and the steering torque is moderately increased at high speed; 2. The torque sensor detects the steering torque generated when the steering wheel rotates, and converts it into an electrical signal and transmits it to ECU for analysis; 3. The power steering motor generates torque after the current of the power steering ECU is activated to assist the steering torque; Recommendations:

Check the electric power steering system.
