Removal and installation the rear suspension spring (Mercedes-Benz E-Class W123)

1. Remove the rear shock absorber or shock absorber strut (on vehicles with a body position control system).

2. Install the spring compressor onto the suspension spring. To do this, compress the spring completely with a trolley jack placed under the diagonal suspension arm, and then install the compressor onto five turns of the spring.

3. Lower the trailing arm to a height sufficient to remove the rear suspension spring together with the upper support rubber cushion.

4. Remove the rubber support cushion and release the spring compressor if necessary.

5. Clean the upper and lower spring supports.

6. Installation is performed in the reverse order of removal. In this case, make sure that the lower end of the spring enters the special groove of the diagonal suspension arm. Tighten the shock absorber mounting nuts after loading the suspension with the weight of the car.
