What are the reasons for a car's steering wheel not being straight when driving in a straight line?

[LaCaroline]

Car straight driving steering wheel is not straight reasons are: 1, the steering wheel is crooked, when driving and letting go of the steering wheel, there will be no deviation phenomenon, this is simply a crooked steering wheel, it may be that the steering wheel and steering column have undergone relative rotational displacement; 2, letting go of the steering wheel the vehicle will deviate, this belongs to the car deviation, not the steering wheel's problem, four-wheel alignment and car dynamic balance need to be done; 3, steering gear failure; 4, the vehicle's lower stabilizer bar deformation. Steering wheel not being straight means that the car wants to maintain straight driving, the steering wheel must be turned a certain angle, if placed in a horizontal position it cannot drive straight. The car steering wheel is tilted and does not automatically return to position after turning.
