The BMW X3 high speed steering wheel shakes, and the BMW X3 idles shakes

The steering wheel of the car shakes, this situation is very common, some car owners can feel a strong steering wheel shake when driving the car at high speeds, when the speed reaches 80-100km h or more. In this case, most of the problems occur in the tires of the car, because the uneven distribution of the mass of the whole part of the tire will cause the wheels to rotate at high speed, and there will be a dynamic imbalance state, which will cause the steering wheel of the car to shake seriously while driving. In this case, it is necessary to align and dynamically balance the tires of the car, and in serious cases, the tires must be replaced.

In addition to the tires of the car, there may also be shock absorber failure, frame deformation, excessive meshing clearance of the main and driven gears of the final reducer, etc. If the steering wheel shakes when braking while driving, then it is very likely that the brake force is too strong and too frequent, which may cause the brake disc and brake pads to overheat and deform when cold, causing the steering wheel to shake.

Generally, the symptoms can be solved after replacing the brake discs and brake pads. If the speed of the vehicle is not fast, but the steering wheel shakes, it is possible that the steering belt of the mechanical steering system will slip when the belt is too loose, which will also cause the steering wheel to shake, and there will be shaking and abnormal noise when the steering transmission system is loose and the gap is too large, but this situation is rare.

It's best to do a 4-wheel alignment, and then check if the tire pressure on the two tires on the front axle is normal, telling that the shake is usually caused by the front wheel counterweight or the pressure is not quite enough.

Hello, the idle jitter is caused by poor air intake, and you need to clean the throttle to match it [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The old X3 is an N52 engine, and older cars need to consider the aging of components, especially the ignition coil, carbon deposits, and air leakage of various rubber pads, etc., which need to be determined by the data flow to determine the direction of the fault. The new X3 is an N20 engine, currently only considering basic maintenance, throttle, fuel injector, carbon deposit, spark plug, program, if your car's mileage is less than 20,000, do the programming first and then test the car to confirm. Hope it helps.

When driving on bumpy roads, the steering system of the vehicle will shake left and right with the change of suspension height, that is to say, the amplitude of the shock absorber buffering the road surface is transmitted to the steering wheel, the steering wheel and the steering system are closely connected, and the suspension left and right shaking is directly reflected on the steering wheel, which is a normal phenomenon.

Hello! The tires are dynamically balanced, and the suspension and steering mechanism are checked for loose clearance.

There are 2 possibilities for vehicle shake:

First: At high speeds, if the vehicle feels vibration from the chassis or direction, please balance the steering wheels (mostly front wheels).

Second: If you are driving at high speeds, if you press the brakes lightly and there will be directional shaking, please clean or replace the brake pads and brake discs.

Car steering wheel.

This situation is very common, and some car owners can feel a strong steering wheel shake when driving a car at high speeds, when the speed reaches more than 80-100kmh. In this case, most of the problems occur in automobile tires, because the uneven mass distribution of the overall parts of the tire will cause the wheels to rotate at high speed, and there will be an uneven and balanced state, which will cause the steering wheel of the car to shake seriously while driving. In this case, it is necessary to align the car tires on four wheels.

and dynamic balancing, and in serious cases, the tires should be replaced.

In addition to the reasons for car tires, it is also possible that the shock absorber is the damper.

Faults, frame deformation, excessive engagement clearance of the main and driven gears of the final reducer, etc. If the steering wheel shakes when braking while driving, then it is very likely that the braking force is too strong and too frequent, which may cause the brake to brake the Changchang pang.

The brake pads overheat and deform when cold, causing the steering wheel to shake.

Generally, the symptoms can be solved after replacing the brake discs and brake pads. If the speed of the vehicle is not fast, but the steering wheel shakes, it is possible that the steering belt of the mechanical steering system will slip when the belt is too loose, which will also cause the steering wheel to shake, and there will be shaking and abnormal noise when the steering transmission system is loose and the gap is too large, but this situation is rare.

You'd better do a 4-wheel alignment, and then check whether the tire pressure of the two tires on the front axle is normal, and tell the shake to do a shovel that is generally caused by the front wheel counterweight or the unequal pressure of the macro balance.

Hello, is it idle jitter or running jitter? If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Summary. Stagnation generally appears in electronic assistance, now the vehicle in order to reduce costs, are the use of electronic power steering wheel, electronic power generally after a period of time due to the power motor related parts gear, bearings and other situations resulting in jamming, such as the lack of grease caused by jamming, worm and other parts of the bearing failure jam, this kind of problem must be claimed during the warranty period, after the warranty needs to be disassembled and checked, the bearing can be replaced, the lack of grease is applied with grease.

Hello. The following answers have been made based on your questions.

According to your description, it should be caused by the looseness of the steering system, you need to check whether the steering tie rod ball joint, steering machine, direction column, and shock absorber bearing are too large, and it is recommended to go back to the store for repair if there is a problem.

Look at what kind of steering machine you have, at first it was mechanical-hydraulic assistance, and later it was changed to electronic directional assistance! Mechanical hydraulic power assist is generally abnormal noise** is the ball head or power pump throttle valve in the direction machine, most of the electronic power assist is caused by the lack of oil inside the direction machine, it is recommended to check in detail!

Checked, none of these problems you said.

The 2020 X3 is an electronic boost.

Do you feel like the steering wheel is getting heavier?

No. When the car was cold today, there was no direction on the spot, and it reappeared after driving a few kilometers.

If there is a direction jam in the individual car of the electronic booster, focus on checking the electronic power assist part, the general power assist gear lubrication is less dry caused by the jamming, part of the part is caused by component problems such as bearings, and it may also be a motor problem.

There is no sound, it is the feeling of being on the steering wheel.

Stagnation generally appears in electronic assistance, now the vehicle in order to reduce costs, are the use of electronic power steering wheel, electronic power generally after a period of time due to the power motor related parts gear, bearings and other situations resulting in jamming, such as the lack of grease caused by jamming, worm and other parts of the bearing failure jam, this kind of problem must be claimed during the warranty period, after the warranty needs to be disassembled and checked, the bearing can be replaced, the lack of grease is applied with grease.

It is really difficult to judge the cause of the failure just by listening to the description, and if there is a problem during the warranty period, you can go to the 4S shop to apply for free treatment or replacement, and find a reliable repair shop to investigate and solve the problem after the warranty period, so as not to affect your normal car!
