Automotive steering system fault FAQs

Automobile steering system common fault is mainly: the steering wheel rotation is too large and manipulation of the instability, the front wheel, steering the heavy head, wandering. Steering wheel transport is too large, unstable manipulation check steering pump ball head, the place such as the king pin and bushing, wheel bearing wear, such as severely worn or clearance overrun. Repair should be adjusted. If no excessive wear or clearance, you should check: first, the abrasion of steering worm gear and worm, or clearance is in accordance with the provisions, such as the large clearance should be adjusted; Second, wear parts of the steering device together, or whether to adjust too loose; Third, the redirect or installation parts loose; Fourth, the steering arm loose.

When the car running deviation, can check the following: whether the tire pressure is equal to or tire diameter are equal; Whether the wheel bearing side too tight; On both sides of the spring steel plate is uneven stretch or deformation; Before the beam is correct, camber Angle are equal; Steering knuckle arm, steering knuckle for bending or deformation; Rear axle shaft for bending tube; Wheel base on both sides are equal.

Check the wheel dynamic balancing. Tire assembly is correct, check whether the tire wear uniform, check the balance block assembly is correct. Check the wheel rim for deformation; The deflection of wheels for lateral or radial swing; Shock absorber for loose or wear; Steering linkage section, horizontal, straight or redirect or assembly for loose; Spring steel, U bolt clamping bolt for loose or damage; The Angle is correct; Tire pressure is correct. Except by high-speed put head to check the contents of the project, especially emphasize the check to the top of the following: tire pressure is correct; Steering knuckle bearing ever loose; To horizontal, straight linkage section ever loose; If there's any loose for steering gear assembly; Spring steel, U bolt clamping bolt for loose or damage; Spring plate whether residual deformation.

About maintenance the car is the best way is often checked the car; you will find problems early and avoid unnecessary losses. Here we recommend some car diagnostic tools can help you test your car by yourself, such as: Launch X431 IV, Launch X-431 PAD, Launch X431 Pro3, Autel MaxiSys MS908 and so on.
