Check the elastic characteristics of the springs according to the data below, having previously compressed them three times until the coils touch.
Visually check the condition of the elastic bushings of the rods, whether the rods themselves are deformed and whether there are cracks on the brackets of the rear axle beam and the body. When broken or «buckling» rubber bushings, replace them. Straighten the deformed rods, weld the cracks on the brackets.
