Jetta deviation Jetta deviation, Jetta steering wheel deviation what s going on

Hello: For the question you asked, the reasons for deviation can be summarized as follows: 1

The caster angle of the front wheel kingpin is asymmetrical left and right, and the deviation is exceeded. The vehicle deviates from the side of the caster angle towards the kingpin; 2.The camber of the front wheels is asymmetrical from side to side, and the deviation is exceeded.

The vehicle deviates towards the side with the highest camber angle of the front wheels; 3.The camber angle of the rear wheel is asymmetrical left and right, and the deviation is exceeded. The vehicle deviates towards the side with the smallest camber angle of the rear wheels; 4.

Changes in the wheelbase of the vehicle can be observed according to the retraction angles of the front and rear axles. If the sum of the front and rear setback angles is exceeded, there will be a perceptible mistracking towards the side with a smaller wheelbase. In addition, the four-wheel alignment instrument cannot detect the deviation factors

5.side slippage, mostly caused by tires; 6.uneven tire pressure or inconsistent patterns; 7.

brake asymmetry and slippage; 8.unbalanced steering assistance; 9.Suspension parts are worn and out of alignment.

Since the four-wheel alignment instrument cannot detect all the deviation factors, it is sometimes possible to see that everything is normal from the positioning instrument, but the vehicle is still running off, then it is necessary to check item by item, I hope mine will be helpful to you.

For more information, please visit the online car market.

Step on the brakes to see if the sub-pump is not working, refueling is broken, go and check it again, all repaired, the positioning is good, first press my inspection is not all over the warranty is just right.

Here's why:

1. Four-wheel alignment does not necessarily ensure that there is no deviation, because positioning mainly solves the stability of four-wheel driving. Generally, the steering wheel of a sedan is designed with 5% free travel, and the deviation in this direction is within the normal range. If you don't turn back to the right direction, you will naturally turn to the right and then deviate to the right, and turn to the left and then to the left.

2. If you do deviate or return to the wrong place, you can check that the tire pressure on both sides is not the same, or the tire wear degree is not the same, and it is time to change the tire; Secondly, check the direction stabilizer bar and steering machine, the steering machine is mechanical, it may be worn too much, or the steering wheel tie rod is loose and the gap is large, and it should be checked before positioning. If there is no damage to the parts, it means that the clearance of the steering machine is too large, and the steering wheel can be corrected by adjusting the toe-in, and it can also be replaced if the steering machine is problematic.

3. The direction automatically returns to the right speed slowly, first check that the car is powered by hydraulic machinery and then see if there is a lack of hydraulic oil for qualitative treatment.

Jetta according to what you said, if you do the positioning or not, I suggest that you can check it yourself, drive a distance of about 50 meters, hands off the steering wheel, if the car deviates very seriously within this distance or even to the road, it is a phenomenon of deviation. In one case, if there is a deviation phenomenon when braking, check the braking force, which should be caused by uneven distribution of braking force. In order to check whether the wear degree of the tire and the air pressure of the tire are consistent, the wear degree is large or inconsistent, which will produce the phenomenon of deviation and noise.

Finally, it is not clear whether your vehicle has been involved in an accident, if there has been an accident, you should check whether it is due to the abnormal position of the tie rod of the front suspension of the vehicle, as well as the inspection of the chassis.

Real Jetta. According to the condition of your slim right, because you have not seen the current car, I can only help you analyze the main reason for your car's deviation is teasing: frame deformation, suspension system damage and deformation, front axle deformation, loose steering knuckle and improper toe-in adjustment, as well as inconsistent left and right tire pressure, etc., resulting in the car in a straight line and braking are misaligned.

Remind you to also check whether the position of the front wheel of the Hengshan vertical stove lever is offset to one side, you can adjust the horizontal rod to eliminate the phenomenon of vehicle deviation, pay attention to the premise that the four-wheel alignment is normal.

It is recommended that you go to the 4S store to have a careful examination, because for specific reasons, you still need to see the current car to be diagnosed.

The car deviation should first look at the front suspension, whether the ball joint arm is loose, whether the tire tread is seriously worn, wear deviation, do a four-wheel alignment adjustment, another situation if the vehicle has an accident, it is necessary to measure the difference between the left and right front and rear wheel base, if too much will also run off, the vehicle deviation at high speed must have hidden dangers. If the direction of the car deviates, if it is a normal vehicle that has not had a major accident, it will generally be caused by the following reasons:

1. The left and right tire pressure is inconsistent This is the most common reason for the steering wheel to deviate, under normal circumstances, the front and rear tire pressure is generally on the left and right, and the front tire may be slightly lower. In the process of time driving on the car, the ground contact area and force of the left and right tires must be uneven, and the tire pressure will be inconsistent after a long time, and the direction of the car will also be biased to the side of the low tire pressure. Workaround:

Just make up the tire pressure.

2. Inconsistent wear of left and right treads There are similar reasons as Article 1, and the inconsistency of car steering and rolling on the road surface will also be different in the wear of tires. However, when the tread on one side is worn too much, its diameter will be smaller, and the direction of travel will also be biased to this side. Workaround:

In addition to changing the tire, if it is a front tire, it can be swapped with the rear tire on the same side.

3. The shock absorber springs have different degrees of metal fatigue, that is to say, the strokes of the springs on both sides are inconsistent, one high and one low make the body unlevel, resulting in the vehicle deviation. If you still deviate after the first two loose plum adjustments, this may be the reason.

4. Brake system failure, potato brigade is often referred to as partial braking. If the brake cylinder on one side is not working properly, the brake pad return is not complete enough, and the wheels on this side are kept braking during driving, which will also cause the vehicle to deviate.

Is it that your four-wheel alignment is not done well? It's not very expensive, you're looking for a bigger repair shop to do it.
