We replace the rear suspension springs in case of breakage or "drawdown" of one or both springs

Springs must be replaced in pairs, even if only one is faulty

Rear coil spring: 1 - bolt (lower part of stabilizer link); 2 - bolt (rear lower arm, outer side); 3 - rear coil spring; 4 - the upper gasket of the spring cup; 5 - lower spring cup; 6 - compression stroke buffer (from the side of the spring); 7 - compression stroke buffer (body side)

Springs differ in stiffness and are marked with marks on the coils depending on the stiffness class

Springs of the same stiffness should be on both sides of the car

We prepare the car for the task and hang the back of the car on stands

Remove the wheel from the side of the spring to be replaced

We clean the threaded connections of the lower transverse arm and treat them with penetrating lubricant

Using two 17 wrenches, loosen the bolt nut

We install a jack or an adjustable stop under the lower arm and raise it a little, thereby relieving the load from the bolt

Slowly lower the jack until the suspension spring is completely loosened

Remove the spring

Remove the upper rubber support from the spring

If the support is strongly compressed or deformed, we replace it

Before installing a new spring, we put the upper support on the coil so that the ends of the spring fit snugly into the groove of the support

Install the spring in reverse order

When installing the spring, we rest its lower coil against a special protrusion of the support cup of the lower transverse arm
