Notes on repairing air-spring struts
Information
As of a mileage of 200,000 Km it is recommended that the air springs be replaced per axle if there is damage to one air spring.
If the shock absorbers leak, the complete air spring strut is to be replaced. The oil of the shock absorber can damage the roller.
When depressurized, the air spring must not be twisted. There is the danger that the roller in the inside of the air spring will be damaged by bending or
folding and thus significantly reduce the running time.

1. Before loosening the air lines in the installed state, check if the rolling boot is still filled with the residual pressure of approx. 3 bar. To do this,
press on the rolling boot of the air spring with your thumb. The rolling boot must give perceptible resistance. If no significant resistance can be
felt, the air spring is depressurized and must be replaced along with the residual pressure retaining valve.
