Checking the technical condition of the front suspension

Wash all parts thoroughly before checking.

Protect rubber parts, bushings and protective coatings from solvents when washing.

Springs

Check the elastic characteristic of the spring on the control points (pic. 4-17), having previously compressed it until the turns touch.

Note. Length under load 3425 N (350 kgf) springs are divided into two classes: class A - length more 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 elasticity of the spring does not correspond to the data in fig. 4-17 or deformation may cause the spring to malfunction, replace it.

Check up a condition of rubber basic linings of springs; if necessary, replace them with new ones.

Barbells

Check:

• whether the rods are deformed; if possible, straighten them;
• are there any cracks on the brackets of the rear axle beam and body; if cracks are found, repair the brackets;
• the condition of the elastic bushings of the rod hinges; if necessary, replace them with new ones using tool kit 67.7820.9517.
