Protect rubber parts, bushings and protective coatings from solvents when washing.
Springs. Check the elastic characteristic of the spring on the control points (pic. 4-14), having previously compressed it until the turns touch.
Install springs of the same class on the rear suspension as installed on the front suspension. In exceptional cases, when springs of class «A», and there is no such class of springs for the rear suspension, it is allowed to install springs of the class «IN». But it is not allowed to install class springs on the rear suspension «A», if the front suspension is equipped with class springs «IN».
Check for spring deformation. If the elasticity of the spring does not correspond to the data in fig. 4-14 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.
Pic. 4-14. Basic data for checking the rear suspension spring.
Rods. 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 the tool kit.
