If cracks or deformations of the coils are detected by inspection, the spring is replaced with a new one. The draft of the spring is checked, for which the spring is pressed three times until the coils touch, then a load of 295 kgf is applied to it. The length of the spring under the specified load must be at least 233 mm. If the yellow marked spring (class A) has a length of less than 240 mm, change its marking to green (class B).
The compression of the spring is carried out along the axis of the suspension spring, and the supporting surfaces must correspond to the surfaces of the shock absorber and body support cups. Check the condition of the rubber spring pads. If necessary, replace them with new ones.
