Before checking, rinse all parts thoroughly.
Protect rubber parts, bushings and protective coatings from solvents when washing.
Springs
Check the elastic characteristics of the spring at the control points (Fig. 4-17), having first compressed it until the coils touch.
Fig. 4-17. Basic data for checking the rear suspension spring
Note: According to the length under a load of 3425 N (350 kgf), springs are divided into two classes: class A - length greater than 278 mm and class B - length equal to or less than 278 mm.
Class A springs are not marked, while class B springs are marked with black paint on the outside of the coils.
Check for spring deformation. If the spring elasticity does not correspond to the data in Fig. 4-17 or deformations may cause the spring to malfunction, replace it.
Check the condition of the rubber spring support pads; if necessary, replace them with new ones.

Barbells
Check:
- are the rods deformed?; if possible, please correct them;
- are there any cracks on the rear axle beam and body brackets; if cracks are found, repair the brackets;
- condition of elastic bushings of rod hinges; if necessary, replace them with new ones using the tool kit 67.7820.9517.
