Due to the design of the suspension, the shock absorbers can only be removed and installed in series.

Removal

Open the trunk, remove the protective cover from the upper shock absorber stop. Unscrew the hex nut. If necessary, hold the shock absorber rod with a wrench. Remove the cup and rubber buffer.

For vehicles with adjustable ride height

Unscrew the union nut and disconnect the pressure line from the shock absorber.

Press the bracket slightly in the shock absorber area with a hydraulic lift to ensure that the spring does not pop out.



Unscrew the hex bolt securing the shock absorber to the rear suspension bracket.

Installation

Before installation, check the shock absorber, see item 12.4.

Check the rubber buffer, replace if necessary. Use new buffers with new shock absorbers.

Note: Starting with chassis #2503715, a modified rear shock absorber mounting cup is used. Older vehicles (sedan only) if noise occurs in the area of the rear shock absorber, new cups should be used. The convex side of the cup should be on the shock absorber side. In addition, it is necessary to monitor the changed adjustable dimension -A-.

Insert the shock absorber into the holder on the rear suspension bracket. If necessary, tap the shock absorber into the holder with a polymer hammer.
