How to Determine if a Vehicle is Pulling to One Side?
1 Answers
Start the car on a straight road, maintain a straight line during initial movement, and after reaching a certain speed, release the steering wheel. If the car drifts to one side, it indicates a problem with the vehicle. The following are the causes of vehicle pulling: 1. Uneven tire pressure: Mainly caused by inconsistent tire pressure in the drive wheels. Uneven tire pressure on the left and right sides will change the friction between the tires and the ground, so only consistent tire pressure can ensure the most basic requirement of not pulling to one side. 2. Different tread patterns or uneven tread depth on the two sides: It is best to use the same type of tires for the entire vehicle. At the very least, the two tires on the front and rear axles must be the same, and the tread depth must be identical. 3. Condition of the steering system: The condition of the steering system will also affect the straight-line driving of the car. Excessive wear in connecting parts or looseness caused by wear in bearings, kingpins, or bushings will cause the car to sway during driving and fail to maintain a normal trajectory. 4. Uneven cushioning due to deformation of front shock absorber springs on both sides: The condition of the shock absorber springs can be judged by pressing or comparing after removal. 5. Failure of front shock absorbers: After the front shock absorbers fail, the two suspensions will be at different heights during driving, resulting in uneven force distribution and causing the car to pull to one side. 6. Body deformation: Overall deformation of the vehicle, with a significant difference in wheelbase on both sides beyond the maximum allowable range, can be measured with a tape measure. If the range is exceeded, it must be corrected using a correction platform or replaced.
