Total vehicle alignment refers not only to the steering axle geometry but also to all other axles on the truck and the trailer, ensuring they are parallel to each other and perpendicular to a reference centerline.
This activity usually requires expensive equipment to check the various angles. Due to the high cost, it is recommended to conduct field checks to determine which vehicles truly require a full alignment. The 3 following checks prevent the main causes of tyre uneven wear due to the alignment: Toe-distance, Axle scrub angle, Axle Thrust.
Toe-Distance
The distance between the front of the tyres as compared to the rear of the tyres. The measurement should be slightly wider in the rear of the steer tyres, generally around 1,5 mm.
Axle Scrub Angle
The distance comparison between the left side of the drive axles and the right side. They should be equal or within 3 mm.
Axle Thrust
This occurs when the drive axle thrust line is not in line with the truck’s centerline.
