What is the normal range for wheel alignment parameters?
1 Answers
The normal range for wheel alignment parameters is: single-wheel camber should not exceed 110 on either side, total camber should be around 0.50; single-wheel toe should be approximately 0.15 on either side, total toe should be around 0.30. The instrument will display green to indicate the normal range. The purposes of adjusting wheel alignment data are: 1. Caster angle: ensures straight-line stability and steering return; 2. Kingpin inclination: ensures steering return stability; 3. Wheel camber: increases tire contact area and offsets adverse effects; 4. Toe: counteracts the negative effects caused by wheel camber. Steps for wheel alignment: 1. Drive the vehicle onto the four-post alignment lift and check tire pressure and vehicle height; 2. After lifting all four wheels, inspect the tires for irregular wear or deformation. If wear meets standards, check for looseness in the steering ball joints and ensure the lengths of the left and right tie rods are consistent; 3. Inspect the upper and lower suspension, stabilizer bar, subframe, and chassis for deformation or looseness; 4. Check the rear axle, transverse assist rod, and rear tie rod for deformation and whether the rubber bushings are loose; 5. If no abnormalities are found, lower the vehicle and shake it several times to confirm the suspension system is in normal condition, then remove the wheel alignment locking pins.
