Note that it is not necessary to try to unscrew both axle suspension beams from the axle, since during installation a certain angle of their location relative to the axle is adjusted. If possible, unscrew both beams from the bottom of the vehicle. If this is not possible, optimally mark the mutual position of the suspension beam and the axle. in order to install them in their original position during installation.
Loosen the wheel nuts on both sides.
Put the back of the car on the goats and support it.
Unscrew the handbrake cables from the control lever and unscrew the brake hose there. where it is connected to the brake wire.
From the inside of the trunk, remove the protective caps that protect the upper part of the suspension struts. They are located directly under the seat belt loop.
Unscrew the nuts on the ends of the piston rods of both shock absorbers (suspension struts). In this case, the rear axle must be supported with a jack to keep it in the same position for the time being. However, the unscrewing operation is not easy, as car service shops "Volkswagen" use a special key for this. After removing the top nut, remove the leaf disc and unscrew the second nut in the same way. Remove the bottom cover and top rubber bushing.
On vehicles with brake pressure control, unhook the spring from the rear axle caliper.
If the axle is dismantled together with the suspension beams, mark the contours of the beam on the bottom of the vehicle; if the bridge is dismantled without beams, mark the position of both suspension beams on the bridge body (scratch it with a scriber) and unscrew the self-locking nuts on the outside of the beams. Carefully drive the screws inward.
Disconnect the exhaust system from the body in an appropriate way or completely dismantle the rear section of the system.
Slowly lower the rear axle on the jack and remove it by pulling it back.
Installation of the entire place is carried out in the reverse order to dismantling, however, it is necessary to pay attention to the following points.
Slowly raise the rear axle and at the same time insert the piston rods into the trunk holes. The piston rods should already have lower rubber bushings, as well as leaf discs. Put on the top sleeve and leaf disc and tighten the nuts to a tightening torque of 25 Nm.
Put on the leaf disc and tighten the second nut. It is tightened to a torque of 15 Nm.
When installing the axle on the body, proceed as follows, depending on whether the suspension beams have been dismantled or not.
If the beams have not been unhooked from the bridge, bring the bridge to the underside of the vehicle bottom, center the screw holes and tighten the screws. Tighten the shoulder screws to a torque of 70 Nm
In case the girders have been unhooked from the axle, insert the rear axle with supports into the girders and center the axle body until the applied markings are again on the same axis. The body of the bridge should form an angle of 12°±1°relative to the suspension beams. This guarantees the correct preload of the rubber bearings. Insert the screws and drive them in from the inside out: tighten the new self-locking nut (with welded washer) up to 80 Nm
In case the suspension beams have been unscrewed from the axle and from the bottom of the vehicle, first screw the suspension beams to the axle to restore the original angular position. Screw both screws of the axle body to the axle, tightening to a torque of 80 Nm (new nut with weld washer). Then hand-tighten the fixing screws on both hanger beams and center the right beam so that the screws are in the middle of the slots. In this position, tighten the screws to 70 Nm. Now, on the left side, between the suspension beam and the axle body, insert two levers for removing tires and press the beam against the rubber-metal bushing. In this position, tighten the suspension beam screws to a torque of 70 Nm. This operation must be performed by two people (one manipulates the levers and the other tightens the screws).
Connect the handbrake cables and brake hose and adjust the handbrake. Bleed the air out of the brake system.
