Fifth step: Maintenance adjustment
On the basis of comprehensive analysis and diagnosis, the vehicle positioning angle
can be adjusted. The technician should have a clear expectation of the effect of the
positioning angle adjustment. The order of adjustment is as follows:
1. First the rear axle two wheels: rear wheel camber angle→rear wheel toe
2. Then the front axle two wheels: If toe-out on turn is not right, replace the steering
arm →caster angle (for vehicles with engine brackets, always adjust the engine
bracket first)→camber angle→toe (the steering wheel horizontally positive lock at
present).
