The beam is replaced if it is deformed or has other mechanical damage, as well as in the event of a malfunction of its silent blocks.
To perform the work you will need an inspection pit or overpass, a jack, and a support for the car.
Sequence of execution
1. Prepare the car for work (see "Preparing the car for maintenance and repair").
2. Place stops under the front wheels and lift the rear of the car.
3. Remove the rear wheels (see "Wheel replacement").
4. Disconnect the rear brake hoses from the bracket on the beam (see "Brake hoses - replacement").
5. Disconnect the shock absorbers from the longitudinal arms and remove the springs (see "Rear suspension springs - replacement").
6. Disconnect the brake pipe from the working brake cylinder (see "Wheel brake cylinder - replacement").
7. Remove the parking brake cable from the bracket on the trailing arm.
8. Using the TORX E14 key, unscrew the four mounting bolts...
...we remove the hub assembly with the brake drum, move it over the longitudinal lever and place it on the floor or a stand.
If necessary, remove the parking brake cables from the holders.
9. Using an 18 mm wrench to hold the bolt from turning, use a second wrench of the same size to loosen the nut. Similarly, we loosen the nut on the other side of the car.
10. Install stops under the rear suspension beam.
Note: The fuel tank prevents the removal of the right rear suspension beam mounting bolt. To remove this bolt, you need to unscrew the three bolts securing the beam bracket and move the right edge of the beam below the tank.
11. Using a 16 mm socket wrench, unscrew the three bolts securing the bracket to the body.
12. Lower the beam a little, finally unscrew the nut of the bolt securing the beam to the bracket and remove the bolt.
13. Remove the brackets from the beam.
14. Remove the mounting bolt from the bracket on the other side of the car and remove the rear suspension beam.
15. Install the parts in reverse order. The nuts of the bolts securing the beam arms to the body brackets are finally tightened with the vehicle standing on the ground. Tighten the bolts and nuts to the prescribed torques (see table 11.3.1).
