Template for adjusting the longitudinal angle of inclination of the axis of rotation.
The angle is adjustable by changing the number of shims on the bolts of the lower arm axle.
So, rearrangement of one washer 0.5 mm thick from the front package to the rear one gives an increase in the longitudinal angle by 36–40', while the camber decreases by 7–9', and vice versa.
Adjusting U-shaped washers with a thickness of 0.5 and 0.8 mm are on sale. These washers must be installed with the slot down.
You can measure the longitudinal angle of inclination of the axis of rotation using a homemade template with a plumb line. A sector is marked on the template, in which, if properly adjusted, the plumb line should be located.
We tighten the nuts on the fingers of the ball joints so that their faces become perpendicular to the longitudinal plane of the car, and apply a template to them.
Attention! The difference in the values of the longitudinal angles of inclination of the axis of rotation between the right and left wheels should not exceed 30'.
