3. Check the elastic characteristics of the springs at the control points, having previously compressed them three times until the coils touch.
Attention! The rear suspension springs of the VAZ-2104 car under a load of 3285 N (335 kgf) are divided into two groups: A - longer than 273 mm and B - longer than or equal to 273 mm. Group A springs are marked with light brown paint, and group B - with blue paint on the outer side of the coils. The rear suspension springs of the VAZ-2105 car are classified and marked in the same way as the front suspension springs.
4. Check for spring deformation. If the elasticity does not correspond to the given data or deformations can cause malfunction of the spring, replace it.
